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 GA 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 gauge like the Cycle Analyst or Batt-man. Many modern displays also have accurate voltage meters so you can go off of the handy chart provided in our battery FAQ to see how the voltage equates to state of charge. 

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. 

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...



Regarding Amps:
These packs will easily put out 30amps (1500 watts) and even more for short bursts (about 50A peak)

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).

Mount compatibility:
See the pictures of the mount on the bottom. This is not the same as previous 4pin or 5pin mounts as the internal structure was recently changed to add additional safety and durability features. Cross-compatibility with older battery mounts is not guaranteed.

Charge port compatibility:
Current model uses a mini XLR. If a charger is bought with this battery as a package deal (i.e. charger is an option on the battery listing, or it is bought as an option in a kit listing along with the charger option) then adapter will be included. For the adapter typically used with latest Luna chargers see this link


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.
