Panasonic 3500 GA cells

This pack is made up of the most exciting (and expensive) battery cells on the market the Panasonic GA (also known as the Sanyo GA) which offers the highest available capacity in an 18650 cell (3400-3500mah) which until now was offered only by the Panasonic NCRB. But where as the NCRB was rated less than 5 amps discharge per cell, these cells are rated at 10amps which is powerful enough for almost all ebike applications. 

This cell may very well be the ultimate ebike battery pack building block because it is both power dense (for long range) and very powerful. 

Our cells are guaranteed to be authentic.

48 Volts

This is a 13S / 48V battery and should work with all 48V systems. Running 13s insures that your battery gauge is accurate on most kits which use cheaper battery gauges. 


This pack uses Panasonic GA 3500 cells which are very energy dense at 3400-3500mah each. When you put 42 of them together you get 10ah and 520 watt hours in a very small size. (read our story on ebike math)

This pack weighs an amazing 5 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. 

50 Amps

This is a high performance pack with our 50-amp continuous BMS with temperature protection built in. (read our article on BMS). It is designed to put out 3000 watts of power, with temporary bursts of up to 5000 watts. Even if your current set up does need this type of amperage, it will not hurt your current set up to have this capability for future builds. Plus, this high-performance cell is designed to last longer than lower quality cells, even under lesser amperage demands. Do not worry about having too many amps available, as your controller will only use them if it needs them, so it's always better to have too many than not enough.

Quality Components

Every ingredient in this pack is top-shelf, from the cells to the BMS, to the cell holders and nickel plates holding it together. We use the XT-60 and XT-90 spark resistor connectors, and our own volt-meter built into the pack. All this comes together to create an 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 it. 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 pack, they also keep your battery from getting too low, charging too high, or getting too hot, and it 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 physical similar size. These packs have more amp hours than any commercial ebike, who skimp and use generic generic cells which are known for being low power density and short battery life.


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

Regarding Amps: These packs will easily put out 50amps (2600 watts) and even more for short bursts. If your kit can handle 52 volts, and needs 50amps or less these are ideal packs for you. In fact these packs will put out 70amp for short amounts of time (about 3500 watts). 

More than likely your controller is less than 50 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. 


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. We use plastic cell dividers to make sure the pack is as protected as possible but it still needs care in mounting. You do not want your pack bouncing around or banging against anything because it can ruin your pack and also be safety risk.

It can easily fit 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 rear rack battery or a back pack battery. It is the ultimate in energy density because it is not in a hard case.

We love to securely duct tape or zip tie this battery to our downtubes on our full suspension bikes and this is a very effective (although not pretty solution).  We can do this because of the incredible small size and light weight of this particular battery. 

(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 for the wholesale price. When you order both a battery and charger from us, the charger will automatically come with the appropriate plug to charge the battery. This battery must be used with a smart lithium charger that charges to a maximum of 54.6V (4.2V per cell)

We really recommend using the  advanced Luna Charger to take care of a quality pack like this, which offers slow-charging or fast-charge modes, and you have the option to charge to 80, 90 or 100 percent. Charging to 80% voltage actually only loses 5% of the potential range, but it will double the life of the battery over charging to a full 100%. The Luna Charger was not an existing charger that we slapped our name onto we special-ordered specific features that are good for our customer, and left out expensive features that were unnecessary, to keep the price affordable.

Some vendors don't care if your expensive battery wears out faster. We understand that sometimes our customers want to charge the battery fast, and want to charge it to 100%, but the battery pack is usually the most expensive part of an ebike, and we want you to know that an option to slow charge to 80% will help your pack stay cool and will help it to last for many years. We also like having a voltage readout on a charger (who wouldn't?), so the Luna charger has a digital voltage readout. We don't just sell ebike parts, we also love actually riding ebikes, and that means we want to make sure the good stuff is available, but we also cut out the fluff to keep our prices the best in the industry.  


Installation and basic info 

The Luna Softpack FAQ





1. My battery pack stopped charging, what should I do?

2. My battery is reading (any #) volts, how much life is left before I need to recharge?



1. Often if this happens it is due to the anti-spark feature built into the BMS. Say you did not properly make a connection somewhere and the wires sparked, the BMS would shut itself down to prevent damage to the system. If this happens the first thing you always want to do is to try resetting the BMS by using your charger to try charging through the discharge connector for a few seconds, maybe a minute. You just run a jumper (basically regular wires) from the charger's connector to the battery's discharge contact, making sure you go positive>positive and negative>negative. At Luna we call this jump starting it, instructions can be found here:  https://lunacycle.com/jumping-your-lu...-battery-pack


This is a 48v nominal pack. As seen in the chart below this pack is full at ~53V and empty at ~42V. For long battery life try to keep voltage between 52-43V most of the time (A charge percentage of between 90%-10%)
