How to use this charger


If you have any issue after using it following the instructions in the video, and are using an XT60-barrel adapter, please check the adapter.

Do this by first unplugging it from the charger. Then plug the barrel into the battery and test for voltage with a multimeter on the other end (the part with the xt60). 




How do I use this with a hardcase battery pack?
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

  1. defective

    Posted by Unknown on Oct 18th 2017

    Mine was also apparently part of a defective batch, as it was dead on arrival. Luna would benefit from some form of OQA on the items that are shipped.

    Would be nice to get info book with this charger because my charger leds were flashing on and of and fan was cutting out ever 3 seconds for the first 30 minutes of use because my battery was dead ,but my volt meter showed it was working , did not know if it was a problem or not. appears to be normal operation

  3. First time using lithium and went with a name I trust

    Posted by Adrian on Sep 17th 2017

    After using SLA's for 3 years quite happily I know I had to upgrade so I got a new second hand 48v 20Ah Luna cube, I decided on that investment to make sure I got a charger to match it. After looking around I decided to go with the 48v mini charger for a variety of reasons, it's ability to charge 80-90% is a good one, the size is perfect, the cost was actually less than local no name lithium chargers that were brobably bulk bought and resold at a handsome profit. Leaving me with a simple decision. The charger had the right connector for the battery which made things easy to put together, I charged the pack for 8 hours and the pack did get rather warm. But on use the pack works well. The charger is simple to use, I cranked up to 100%,waiter till the fan cut out and went about my business. It's quite noise, I wasn't prepared for that, it's also a lot smaller than I imagined. I will end up putting a watt meter in between the battery and charger as I like some visual indication of what's going on but all in all I'm happy with my investment.

  4. not compatible or defective

    Posted by posted bye on Aug 28th 2017

    This charger did not work with my 48V, 12AH Panasonic battery pack. It cycles on and off, and will not charge. It produces voltage, but the controller freaks out for some reason.

  5. Didn't work

    Posted by Unknown on Aug 1st 2017

    Mine was defective. Took 3 weeks to get resolved. Painful drawn out process.

  6. Mine was defective

    Posted by Unknown on Jul 31st 2017

    Can't recommend, mine was defective. Took 3 weeks for Luna to make good on it, customer service was slow and painful to work with. I like that they are here in the U.S. but I'll look elsewhere first. If you do buy from Luna get the 5 Amp charger s the 3 amp units take much longer than you would expect to fully charge.

  7. Quality charger

    Posted by Unknown on Jul 18th 2017

    Works well for me although not sure about the accuracy of the 3 position switch, check your volt meter for best results. Well worth the extra coin for a little faster charging and safety.

  8. Charger not working.

    Posted by Unknown on Jun 30th 2017

    Charger not working. Brand new charger and it worked one time. Apparently there seams to be a problem with the Barrel connector? I am not sure this is the issue as i have checked the voltage from the battery through the XT60 connector and it is good. Also checked from the charger to the XT60 connector and is also good? Luna is sending me a different barrel connector to see if it works.

  9. Super SImple. Super Awesome....

    Posted by John on May 13th 2017

    I love it. But, what can you say. It charges as fast as you should charge any of these batteries really. Had to make a little xt-60 to PowerPole adapter, but that was a small hurdle to clear. I could not be happier.

    I would highly recommend grabbing one.

    Along with everything I have purchased from Luna, this charge is top notch. I bought it to charge my Lifepo4 battery that I bought before I heard of Luna Cycle. The main feature on this charger allows you to charge your battery to 80% or 90% which in turn will give your battery a much longer life, as well as a more reliable power output. Thanks Eric...good stuff.

  11. Great charger

    Posted by Robert A. LaBonte on Mar 6th 2017

    I am quite pleased with this lovely charger. It looks and works great. The three position switch is an excellent addition to this charger. I like that I may custom charge my battery at a longevity enhancing level of 80% and still have the 90% and 100% options for those days that I might need more storage for longer rides. It's definitely worth the little extra cost to have this quality charger.

  12. Solid Value

    Posted by Hurly on Oct 24th 2015

    Great little charger for the money. Quiet fan and long charging leads. Small enough to fit in my luna cycle battery bag so I can charge my battery at work. Good build quality . You won't be disappointed at this price. I fully recommend it.

  13. How to rate a charger?

    Posted by Neil on Sep 22nd 2015

    The unit is very small and compact which surprised me. Nice long cables ending in an xt60 connector for connecting to the battery terminals. No spark when connecting to battery. The unit fully charged the 48V 21AH battery in about 4 hours - I pulgged the battery in to charge the moment it arrived so I could test it that evening. That evening I only rode 20 kms but gave the battery a good hard ride. The unit charged the battery in about 3 hours post ride. The charger has an indicator light which is red when charging and turns green when charged. Pretty simple. I could not tell you if it charges 80% 90% or 100%.I am not measuring AMPS in yet. The unit surprised me by having a fan which is noticeable in an office. The charger and battery fitted inside the lunacycle triangle pack no problem
