  • Pick a custom vinyl skin to add color to your Shark
  • Key lock releases pack from bike
  • Led light battery meter
  • 11.5 or 13.5ah depending on cells you pick
  • Up to 702-watt hours means incredible range in small package  (read article on watt hours)
  • 14s4p = 56 Genuine  name brand grade a Panasonic 18650 cells (see breakdown on 18650 cells)
  • 30amp continuous  BMS
  • Life Span: 400-1000 charges
  • 14.5 x 3.5 x 3.5 " (See pictures for detailed dimensions)

This is a 52v battery designed to squeeze more power out of your stock 48 volt system without damaging your  48v 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 range than a comparable amp hour 48 volt battery.  (read our story on calculating range) With the Panasonic NCR B cells you would have an amazing 700 watt hours, enough to get you up to 50 miles on a low power kit like the BBS02. 

One draw back to the  52v pack is it will not give you an accurate battery reading on kit dash displays made for  48v.  So consider an amp hour guage like the Cycle Analyst or Battman. 

We took the best name brand cells on the market for energy density and stuffed them into this little case to pack incredible range and still keep your ebike lightweight and stealth looking. 

This new slim case is one of the newest ebike cases to hit the market. It  is designed to be as small as possible to fit inside the triangle of most bikes where the water bottle goes  and give a more stealthy look.   You can also mount it in any other place of your choice and it would even make a great backpack battery. This is the same pack loaded with panasonic cells (same cell that Tesla uses)

Ultimate Long Range in a very small size

We designed these packs using a common ebike case, but filled them with quality name brand 18650 cells utilizing the latest battery chemistry to get the highest possible power density. This means despite these packs small size and light weight, they will get you tons and tons of range. These packs have more amp hours than any commercial ebike, who skimp and use generic cells which are known for being low power density and short battery life.  In fact we so disbelieve in generic cells, we are not even offering them as an option. We only offer quality cells in our packs not cheap no name cells like almost everyone else does.

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. 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.

Cell Choice

This pack is crammed full of the highest quality cells in the industry. 52 cells in a 14s4p configuration. That means 4 rows of  14 to give you the voltage and amp hour you need. Depending on the cell you choose you will have 11.6 or 13.5ah which means the amount of range you will get.

Here are your cell choices:

Panasonic GA - 3500mah This cell is the latest innovation, and probably the highest quality 18650 cell on the market. It offers both energy density and high amperage performance...

Panasonic  NCR B 3400 - 3400mah is one of  the highest energy density available in an 18650 cell a However this is not a cell known for high power. So if you are planning to climb mountains or do a lot of off roading at full power we recommend the Panasonic PF Cell instead.  The NCR B will get hot if pushed too hard...and even though the battery has a built in high temperature cut off, getting your pack hot too often will reduce the lifespan of your battery.

Panasonic PF - This cell is an excellent choice if you are running a 30amp or higher controller. IT offers both high performance and descent energy density. It is a 3000mah cell.


Regarding Amps: These packs will easily put out 30amps (1500 watts) and even more for short bursts.

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

Regarding voltage: This is a 14s (52 volt) battery, which means it should be easily compatible with any 48v kit or ebike on the market no matter what the manufacturer might say (they would prefer that you pay more and buy only their batteries).



Most people mount this battery to the downtube of their frame (where the water bottle usually goes) but it’s very versatile where it can be mounted. Because it is so lightweight (7.5  pounds) it can also be used in a backpack.


This is a very easy to mount battery. It has a mounting bracket that will mount to most water bottle screw holes in the frame. If not you can drill threaded holes into your frame to accommodate it. Or you can use zip-ties etc.  Once the bracket is installed it's a breeze to take the battery on and off. So you can have extra batteries that you carry on your ride that would easily fit in a backpack or on the racks on your bike.

Nice battery, terrible mount

Great battery, happy with it. Going on two years strong. The problem is the plastic tabs that hold the battery to the mount all broke off one after the other. The mount is worthless to me now. I ended up strapping this on my rear rack with some heavy-duty bungy cords, but it's a shame the plastic tabs weren't stronger.

luna makes the best aftermarket/custom e-bike batteries on the market.

I have read some of the reviews of the battery packs that are made by Luna and all I can say is this, the complaint's are all bull except for the weak tabs on the mount plate. Other then that this battery does way better then you think. I have my battery mounted to the underside of my full suspension mountain bike with mud, rocks and everything else hitting it and never had one problem. I jump my bike with abandon off of everything I can see and the pack has never come loose. Just don't dick around with your pack taking it on and off needlessly and the tabs won't break.
