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.

Name Brand Cell Choice

Luna Cycle only uses namebrand made in Korea or made in Japan 18650s. This pack is crammed full of the highest quality cells in the industry. 52 cells in a 13s4p configuration. That means 4 rows of 14 to give you the voltage and amp hours you need. 

Panasonic  GA - 3500mah is the highest energy density available in an 18650 cell and this is one of the most expensive and most respected 18650s on the market.

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 13s (48 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). 

Backwards compatibility:
This pack will fit earlier 4 pin shark cradles as new version is essentially a reinforced 4pin case, but this will not fit 5 pin shark cradles such as current gen 52v shark or some production runs of previous 48v sharks. 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 its very versatile where it can be mounted. Because it is so lightweight (7.5  pounds) it can also be used in a backpack.

It even fits easily in one of our triangle bags

Because of its hard plastic enclosure you dont need to worry about padding this battery like you would on one of our shrink wrapped batteries. 

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 zipties etc.  Once the bracket is installed its 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.
