We are proud to announce the Mini Cube battery pack which ultra small and designed to fit on any bicycle frame. 

At only 3.3 pounds this pack can also be carried easily in any small backpack or purse as a convenient emergency pack.

Big is not always better but is almost always more expensive. Because this pack is so small it is reasonably priced.

Also this pack is enough range and more power for most riders as it will put out 30amps which is enough for our strongest kits (the BBSHD mid drive) and its 300 watt hours is enough for most riders (15-25 KMS)  See our story on calculating range for more info

If you find that one pack is not enough you can always buy a 2nd Cube battery. You can even get a parallel adapter which makes it easy to connect two batteries together (they should be charged separately).

We have used a strong rubber shrink wrap on this pack so if you need to you can even use black gorilla tape our extra ultra sticky solution to mount this to your downtube without damaging the shrink wrap.

52 Volts

This is a 52v battery designed to squeeze more power out of your stock 48 volt system without having to change your controller or motor. To get more information read our article on 52 volt batteries.

Not only does the 52v battery give you more power it also gives you more watt hours which means more range than a comparable amp hour 48 volt battery.  (read our story on calculating range)

52 volts is completely safe to run on any of our 48v kits including all our Bafang kits. In fact not only will you get more power but your system will run cooler at lower wattages making it more reliable.

Read another reviewers take on 48v vs 52v batteries here. 


This pack uses Samsung 30Q cells which are very energy dense at 3000mah. When you put 28 of them together you get 6ah and 312 watt hours in a very small size. (read our story on ebike math)

This pack weighs an amazing 3.3 pounds.

Because of its ultra small size it can be mounted in almost any triangle (even full suspension mountain bike) using zip ties or duct tape. It is so small you can probably cram it into a small saddle bag or even your pocket.


Quality Components

Every ingredient in this pack is top shelf from the cells, to the BMS, to the cell holders holding it together, to the nickel plates, to the xt-60 and xt-90 spark resistor connectors and our own volt meter built into the pack. All this comes together to be amazing pack for the price. We are very proud of our packs and the amazing price we are offering them for.

Smart Battery

Luna Cycles builds its packs with the finest BMS (battery management system) available so that you can plug in your battery and not worry about over charging, over heating or running its voltage down too low. Your cells are automatically balanced by the internal BMS in the battery. Our BMS includes such features as temperature over heat  protection and advanced cell balancing. These features not only get the maximum performance out of your bms they also keep your battery from getting to low, charging too high, or getting too hot and will automatically shut off your pack if it senses something is wrong. (read our article on  BMS)

Ultimate Long Range in a very small size

We filled these packs with  the latest battery chemistry to get the highest possible power density. This means despite these packs small size and light weight, they will give you the maximum amount  of range compared to other battery packs of similar size. many commercial ebike, who skimp and use Chinese cells which are known for being low power density and short battery life. More watt hours means more range. (read our story on ebike math)


All 48v Luna Kits and Controllers are compatible with all our 52 volt batteries.

Regarding Amps: These packs will easily put out 30amps (1500 watts) and even more for short bursts.  This battery can be used with 30 amp kits such as the Bafang BBSHD. 

More than likely your controller is less than 30 amps and then you don't have to worry since your controller will only take from the battery what it needs. You cannot fry a controller by selecting a battery with too many amps. Voltage however, you need to be careful with. 

Regarding voltage: This is a 14s (52 volt) battery. This means that with the same controller you will get more power from the same amps. It's fun but you need to make sure your controller can handle up to 58 volts which is what a 52-volt battery puts out when fully charged, otherwise you can fry your controller. 

Most DIY controllers have a range of volts they will accept and most descent 48-volt controllers can handle 52 volts. This is something you must verify about your controller before ordering this battery.  And more than likely the only way to really know is to test with a 52 volt battery.

    Posted by Brady Haskell on 16th Mar 2019

    After building my own battery and cooking it, I’ve got two mighty mini 52v on my demo 8 bbshd down hill bike , the performance is insane . 74k top speed and 60 k total distance up and down hills in Queenstown nz , Luna mate in Perth Australia service and support is outstanding, battery’s arrived in 3 days , other bikers stare at me wizzing past like I’m a hot blond chick , so many questions, I just tell them “pedalling is for poor people, my mate dropped 10k on a mereda? Ebike and I towed him up coronet peak holding my backpack at 20 kph after his battery ran out , can’t rant highly enough, just fuckin buy it !

    Mighty Mini Review

    Posted by Neil Bridgens on 1st Dec 2018

    I’ve got four Luna batteries and have bought over 20. All of them have performed very well. I bought the mini specifically for trail riding to minimise weight. I weigh 106KG and did 18 kms at Woodhill using battery between 0 and level 9. It showed 47 volts at the end and performed perfectly. Recommend if you want to do shutterbug rides where weight is at a premium.

    Bbs02 and Q2 52volt battery

    Posted by Dudley Moore on 5th Jan 2018

    I have added BBS02 kits to my Marin Pine Mountain and Specalized Roll step through for my wife. The small Q2 battery makes this an almost stealth kit, very few people recognise these as e bikes. However when trying them out come back with a big smile, from all the easy power available. We tend to cycle and just use the power for hills so the batteries last well. I have done days up to 55k including numerous small hills and 2 at 260m all on the 1 battery. We have 1 spare battery between the 2 bikes which we just seat bag mount, but have only used it once, that was a solo ride on day 2 of the NZ Timber Trail, and I was using high power when possible. The Trail was deserted due to an early start, loads of fun blasting along at speeds a 66yr shouldn’t attain or can’t without assistance. Lunamate have given good advice and service.

    Mini cube battery

    Posted by Ken on 31st Dec 2017

    Fantastic--Just set the minicube up as the second battery on my Reid fat Bike with BBSHD.I bought it to give me increased range on long road rides, and tried it for the first time today. Did 27klm, mainly on the flat, assist levels 1,2 or 3,and just cruising at about 17klm per hour, and at the end the display was still showing 93%.

    Why not have three

    Posted by John on 30th Oct 2017

    When I set out to build my BBSHD powered Giant Glory Downhill bike I intended to start with the 30Q 52V MIGHTY MINI and build my own pack to be custom shaped to the unique frame that is on all downhill bikes. I wanted a downhill bike because with a BBSHD all terrain is downhill - good suspension, BIG brakes, and sharp handling at speed made sense. I intended the Mighty Mini to be my spare battery when taking off on an outback ride. What I have found is the battery is so capable for power and distance that for most rides I only need one. If I go for a 60km ride, I'll throw a couple in a back pack and swap them out throughout the ride. They are so light and small that having a big heavy battery on the bike just seems stupid. The Mighty Mini being 30Q high capacity and high output cells is a technology step one can't ignore. The space and weight saving makes them stunning for all uses. I'll happily get 20km on most rides given I enjoy peddling with peddle assist and that's probably the thing that changed my thinking. I didn't appreciate just how enjoyable peddling with PAS would be and hence I thought I'd need a heavy big battery and I don't.
