 See our video user manual on this charger here: see video

USER NOTE: Rotary switch: 1 to 5 from the far left will change from 1,2,3,4,5 amp charge current  2 position switch: This changes between 80% 90% or 100% charge capacity


The Luna Charger is Luna Cycle designed charger made for affordability,  easy to use, and smart.  

We made this charger with a surprisingly small form factor, considering it is a serious 300 watt charger. We had our case anodized sea-blue and had an LED display built onto the face of it. When you plug in the charger, the LED displays the maximum voltage it charges to (58.8 for a nominal 52V pack). After you plug in your battery it tells you what voltage your battery is at, and you can monitor your voltage while charging. 

We wanted our charger to be quiet, so we made ours with high quality and reliable fans. From selling other chargers we have realized that cheap fans are the #1 reason for charger failure. Charger failure was our #1 reason for customer support issues last year. Now we will have our own charger that we know is reliable and we can sell with our packs. The Luna Charger is specially designed to maximize 18650 battery pack life by having two very important features:

  1. It  can charge at  1-5 amps (read the benefit of charging slow)
  2. It can charge your battery to 80% 90% or 100% (Read about battery longevity)

Most importantly the Luna Charger accomplishes both these functions while being very easy to use. Both of these two functions are changeable with a flick of a switch so you don't need to fidget with any digital interfaces to change your charge. No instruction manual needed here. This is a very simple charger to use.

 

 

 

 


Charge Slow or Fast

 


We know that charging slow will extend your battery's life but we also know everyone likes (or needs) a fast charge now and then. (read our article on charging fast or slow)

Do Partial Charging
Charge to 80 or 100% percent to really maximize life expectancy

Car manufacturers such as Tesla  have proven that if you do not charge your pack to 100 percent every time you ride, you will greatly extend the life of your pack.

The Luna Charger adds life to your pack without taking a wad of money from your pocket.

 

Additional Information and Specifications

Features: 

     - Charger is configured with reverse polarity, over current, over voltage, and short circuit protections.

     - Fuse protected

     - Precise limit of voltage and current, intelligent control, and avoids over charge.

     - Simple Dual LED indicators : LED 1 shows power is on, LED 2: red shows the battery being charged. Or green shows the battery fully charged (or no load at DC side).

     - Voltage display shows the output voltage inside the charger, and the relative voltage of the battery.

     - Slider switch allows you to do partial charge, 80 or 100 percent.

How to Operate

     1. Check the parameters of the charger and the parameters of the battery to ensure the compatibility of the charger with your battery.

     2. If you need to connect your own connector make sure the red cable goes to positive of your connector and the black wire goes to negative.

     3. Make especially sure that the chargers maximum voltage is the same as your Batteries maximum voltage.  The 48V (13S) chargers max voltage is 54.6V, the 52V (14S) model of chargers max voltage is 58.8V. the 72V (20S) chargers max voltage is 84.0V. Your batteries maximum voltage must match these.

     4. Make sure you plug in your charger. When LED 1 is red, it means the power is on. 

     5. Users can choose how many amps they want their charge current to be with the red toggle on the back of the battery. 5 stands for 5 amps and 3 stands for 3 amps.  A small screw driver or Allen key must be used to change this switch.

     6. The red switch can partially charge your battery to 80% to prolong its life. We recommend you go to full charge only when you are planning a long ride, and you do not store your battery fully charged. The red switch can be moved with a small screwdriver. 

     7. When LED 2 Turns red and the fan stops, the battery is fully charged, and the charger will stop charging. 

Notices

     - This charger is configured for use with Luna 18650-cell battery packs. We make no guarantees about compatibility using other batteries. Please be sure the voltage matches your battery. For example only use the 48V charger on a 48V pack.

     - Using the wrong voltage charger is dangerous and can be a fire risk!

     - It is up to the user to determine if the charger is appropriate for his battery.

 Troubleshooting

     - If the charger does not work properly, please make sure the charger and battery are connected properly.

     - The voltage display will light up even if you are not plugged into the household current. Look at  the red LED on the back of the charger to make sure you are getting power.

     - The charger should be used in a well ventilated area.

     - The aluminum case is an important part of heat dissipation, make sure it isn't covered up or smothered.

     - Check the fuse on the back to see if it is burned.

     - Unplug the battery and then plug it back in to reset. (Sometimes this is needed after changing the position of the percentage charge switch)

 

 *****

 

Q's

1. Why is the LED blinking and the fan is cycling on and off?
2. My charger looks different, what is the difference?
3. How do I use this with a hardcase battery pack?

A's 

1. When balancing a pack the charger will cycle on and off , this is normal behavior. Note that balancing does not occur every time the pack is charged so this may seem like intermittent behavior.

2. This charger is constantly being improved and updated , the switches and functions have changed slightly over time. To determine the version charger you have click here for the KB article.

3. If you buy this charger as part of a combo with the battery we will know to include an adapter that will make it work, if you buy it by itself then please purchase the adapter so we know to include it

  1. Simply a nice charger

    Posted by Marc on Nov 15th 2017

    Noisy... but does the job very well. I like this % selection. Also I like the volt number while charging. This is very easy to operate.

  2. Best and most advanced charger I own.

    Posted by DeMalta on Nov 2nd 2017

    I also purchased a 52V shark park and wanted the best charger to go with that. I did countless hours of research before buying a combo of components for my first ebike conversion. Every bit of research regarding the battery packs, properly care and usage, including charging, concluded that the most important element is proper charging. I just finished my sixth charge at 100% and will now be moving to 80%-90% charge. I use the 4amp setting, 3 is ok but takes longer and 5 is too stressful. This charger allows for a variety of amp and max charge level to allow custom charging/battery conditioning over time. At a cost of $500 just for the battery pack, I want it to last as long as possible, while also providing near peak power when desired. And while this charger does cut output to about 1/4 amp when the pack is full, always best (and stated in the documentation) to pull power when the battery is charged. Don't let run overnight, and always disconnect from battery first, and then AC power outlet. (Same in reverse, outlet first, and then battery.)

  3. Charger works great for my setup

    Posted by Patrick Quinn on Oct 26th 2017

    This charger is easy to operate and charges my Shark perfectly. Mine came with an attachment to fit my Shark. It fits the hole in my charger box. The charging feels safe and is easy to do.

  4. Simply the best!!!

    Posted by Gilberto Restrepo on Sep 22nd 2017

    This is the second 52 volt advanced charger I've purchased from Luna Cycle. The first one I bought a year ago and it's been great. This year I bought another Mighty Mini battery and 52volt advanced charger for my next build and this is the best combination for my Magic Pie builds:-)

  5. High output charger!

    Posted by Rich on Aug 10th 2017

    Initially, my charger did a good job. It brought my new pack up to 57.4 V. After several cycles, the charger would only output about 8 volts. I contacted Luna Cycle about the problem and they offered a replacement. The new unit provided the voltage needed and has both voltage and amperage displays.

  6. Luna Charger

    Posted by Mike Moran on Aug 6th 2017

    Works quickly so far, only 170 miles on the bike.

  7. charger failed after less than nine months, out of warranty

    Posted by Boris on Jul 21st 2017

    I got this 300W charger along with all my other e-bike needs in September 2016. I sat on the stuff for a while, had to get some unexpected small parts - LunaCycle very helpful with this - and finally got the bike built up in December. So the charger has been in use since December last year, and now in July, just seven months later it has failed. The warranty is six months, so now I am out of that investment - a total loss. Now I know to buy a cheaper charger!

    I also think the charger has already been malfunctioning the past several weeks. I'll explain... I had typically charged the battery to 80% with only an occasional full 100% charge to balance the pack. About a month ago it was time again to do a full charge. I was unhappy to notice that the charger was only getting the battery up to 55V even though it was set to give a 100% charge (58.8V was full charge for the new battery). I thought to myself this battery is losing capacity really quickly - disappointing but I knew they do that over time. Now I wonder if this was a sign of imminent charger failure, and the battery has not declined in capacity (so much)?

    The replacement charger I will now have to get will answer that question.

  8. much better

    Posted by David Wesley on Jun 24th 2017

    This charge is much better than the older models. more charging options

  9. Nice Charger

    Posted by Erroneass on Jun 21st 2017

    nice charger, quality case, easy to use selector knobs, I am pleased with this charger

  10. Only option that makes sense

    Posted by RNL on Jun 1st 2017

    Your battery is the most expensive part of your ebike. Not taking good care of it will cost you and could be dangerous. Cheap chargers can blow up (mine did!!) and can damage your battery.

    You can adjust the amps and charge %. Those 2 features can double the life of your battery. What's that worth to you?

  11. Nice Charger

    Posted by Michael T. on May 19th 2017

    PROS:
    For the 'Premium, Top Of The Line' charger that LUNA sells, it does the job very well, aspects of of charging are well covered, other than the option of a balance port.
    Balance charging can be done on the bare pack with a hobby charger when the leads are installed....
    CONS:
    Unfortunately, the sticker on the top of the charger was applied crooked, this makes it look like a cheap eBay discount charger.

  12. The best

    Posted by Larry Hammer on Apr 30th 2017

    Works great and good quality part inside and out

  13. Great Charger

    Posted by Bike Crazy on Apr 16th 2017

    Works well. I used it at three amps and it took about four hours to charge and the battery nor the charger ever got hot. and I like the read out so you can see how many volts the battery has charge too. Great product thank Lunar.

  14. Great charger!

    Posted by James Hansen on Mar 13th 2017

    I am very pleased with this charger. The features are great being able to choose the charging voltage (80/90/100%) and the charging current (1-5 amps) is great. This gives me a lot of control over how I charge the battery. Also having the digital readout is a nice feature to see what my batteries voltage is while charging.

    A product that I would be happy to recommend!

  15. over built anodized electric blue beauty WOW!

    Posted by thomas anthony cirillo on Feb 23rd 2017

    super service & got back to me in short order best charger ive ever used & ive owned 8 or 9 in the 7 years ive been rideing e bikes heavy duty charger monster thank you for being thom cirillo long island new york

  16. You want one

    Posted by Nick on Feb 20th 2017

    Great charger with all the options including digital volt readout,1-5 amps charge rate,% charge selection and awesome customer service.

  17. This is how a charger should be made

    Posted by Bryan Pettett on Feb 10th 2017

    I am so tired of those cheap Chinese chargers that die the firs time they get warm. You can see the quality as soon as this arrives and it seems to be worth every penny. The different charge abilities are priceless. It is nice to be able to charge the percentage. If you need a e bike charger or anything else that a charger of this size is necessary then look no further now sure this is all you need.

  18. so simple

    Posted by Mad Max bike builder on Jan 29th 2017

    Makes slow charging and/or partial charging almost completely idiot-proof for us non-engineers.

  19. Great charger

    Posted by dave mac on Dec 27th 2016

    One of the things I really like about Luna is there you tube videos showing how to do the most basic stuff like use this charger. Love it guys keep it up.

    Me being new to this stuff even the most basic things like charging can bring up questions, and seeing a you tube video on how to use the thing was just so nice.

    And the setting this charger comes with really help customize the charger to the users needs.

  20. Nice charger!

    Posted by Nick on Dec 24th 2016

    I love all the features and especially that you can charge at 5 amps when you need a quick charge. After almost a year my early model charger developed a glitch and was promptly replaced by Luna Cycle-way to stand behind your products guys!
