This Charger is a very small electric bike charger for 52-volt battery (14s 18650 lithium ion) which charges to a maximum of 58.8 volts.  

We are selling a quality charger which is small and robust, made from quality aluminum and nice blue color made to quality specs with a reasonable price.   

This charger has a quality xt60 connector. We provide a male connector so that you can easily convert your existing ebike battery to the quality that is the xt60 without soldering. (read our story on ebike connectors)

It is a 2.5amp charger which will charge a 10ah battery in about 4 hours. When the battery reaches close to full the charger automatically slows down and shuts itself off when it reaches a maximum of 58.8v.

This charger was designed to be used with our 14s packs which is 52v lion. If you are using this charger for your own battery pack make sure the voltage matches what your battery pack requires for maximum voltage. This charger will not work on most ebike packs sold as 48v packs, it is a 52v charger.

Incorrectly charging a battery pack can damage your pack and be a fire hazard!

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. Great very smart charger

    Posted by John Howell on Aug 16th 2017

    I have a amp watt meter connected when I charge, and you can see it starts out at 2.5 amps for awhile and then throttles down as it goes. Toward the end it may only be putting out a fraction of a amp. sometimes you can see fraction of a amps go up and down with it trying balance the cells out. You can only see it if you connect a watt/amp meter in between the charger and battery.

  2. 100/90/80

    High quality with options other don't offer.

  3. Elegantly Simple. A perfectly polished product.

    LunaCycle must be proud to stand behind this product. This charger brings my whole build together. It's incredibly easy to use and abstracts out all of the complicated details about battery charging (voltage, amps, all that EE nonsense...)

    Just plug the charger into an outlet,
    Set the charge level (80%, 90%, 100%),
    Plug in the battery,
    Wait for green lights.

    Easy Peasy.


    Worth it's weight in precious metals. <3

  4. charges well, but noisy fan

    Posted by Unknown on May 17th 2017

    The charger is compact and comes with good length cables. xt60 connector included. Charges the mighty mini battery very well. The only complaint is the tiny and noisy fan.

  5. Great customer service

    Posted by Unknown on Apr 11th 2017

    Action was steadfast. Recommend them!

  6. Great charger! Makes your battery live longer!

    Posted by Dayn Anderson on Mar 13th 2017

    These chargers are cave-man simple, and do something that no other I have seen does, gives an average person the ability to charge their battery at just 80%! No more having to have a high dollar Hyperion (mine was $130 that I got for LiPo), calculate what voltage would be approximately correct for 80% to add life span to the battery. As with all my Luna chargers, (I have 2 now, but have built several kits with them) the quality is self evident, came with a informative users manual too. Keep up the good work Eric & Ashley! The more I see, the more I am just sold on Luna, been over a year our first customer's charger with no problems, I am sure this one will be no different.

  7. Great control for a great price

    Posted by Matthew Shirley on Feb 28th 2017

    3 amps is plenty for home charging my 7ah battery. I enjoy being able to select 80/90/100% charge endpoints. The only issue I have with the charger is the fan noise, although Luna representatives assured me the fan in newer revisions will be quieter.

  8. beautiful blue color and works.easy to use with simple controls

    Posted by jill vaccaro on Feb 17th 2017

    it works .

  9. 52v 3amp mini charger

    Posted by Dave Robertson on Feb 3rd 2017

    Quiet operation..nice bright leds designed for accurate charging voltages (80,90&100%) charge.
    It gives me control in order to extend the lifespan of my Luna battery!!......highly recommended.. would buy again. The 100% charge allows the bms to balance the battery cells since 89-90% charge will not trigger the bms to cell is the best of both worlds!!

  10. Does the job...

    Posted by john mellor on Nov 21st 2016

    Three charge percentage settings - 80%, 90%, and 100%. I've read that it's good for battery to slightly 'underchage' if full charge not needed. Pull plug and reinsert if changing settings in middle of a charge. Good fan prevents overheating.

    Had slight problem with one end of the plug that inserts in battery. Was able to fix but Luna quickly sent me a free replacement... top notch service as usual.

    Would buy this product again from Luna.

  11. 52 volt charger.

    Posted by John Osborn on Jul 18th 2016

    This unit is exactly what it is advertised to be. It works as expected and comes with a male-to-male adapter and spare fuses, both helpful if needed.
    Overall, I'm pleased with this purchase

  12. Decent charger

    Posted by raymond newport on Jun 24th 2016

    Works as advertised. Nothing special, auto off when. Fully charged.
