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 (10-30 miles)  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).

Samsung 30Q

This pack is made up of some of the most exciting (and expensive) battery cells on the market the Samsung 30q which offers both high energy capacity and high amperage performance.

The reason why quality cells are especially important in a small pack like this is that each cell needs to put out high power to sustain big power in such a small pack.  That is why we use only the latest and greatest 18650 cells in this small pack.

Our cells are guaranteed to be authentic.

52 Volts

This is a 52vbattery 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 52vbattery 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.

This pack uses Samsung 30q cells which are very energy dense at 3000mah. When you put 28 of them together you get 6ah and 300 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). 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. 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 is ideal for 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.


This is a rectangular soft shell pack and we recommend that you pad it well in your installation to ensure the cells are not damaged.  You do not want your pack bouncing around or banging against anything because it can ruin your pack and also be safety risk.

Make sure if it is mounted to your frame it is firmly mounted so it does not shake or jiggle, and proper padding is used when needed.

You can easily fit 3 of these in  one of our triangle bags but it must be padded to make sure it does not get banged against your frame. 

This also makes a very good back pack battery. It is the ultimate in energy dense small battery pack.

(read our article on mounting an ebike battery for more information).

Important note regarding charger:

Does not include a charger but you can add a charger from our charger section. We recommend you only use a charger purchased from us to ensure compatibility (as long as you select one of our 52v chargers).  We really recommend the Luna Charger to take care of a quality pack like this which offer slow or fast charge modes, and charge to 80, 90 or 100 percent.
