Warning using this pack will void your factory warranty!

Luna Cycle and FLX are not responsible if you damage your motor or controller riding with this hotrod upgrade. 

HOT ROD AT YOUR OWN RISK!

 

This battery will upgrade your FLX into a 48v ebike which will give you significantly more power and speed by at-least 20 percent.

In our opinion the FLX ebike upgraded to 48v brings the bike to life and makes it a very trailable bike.

Over volting is a common hotrodder's tactic, which gives you more power and higher top speed but will make your bike less dependable.

This is a battery designed to replace your stock FLX battery using the without changing any of your hardware.

Care must be taken not to push your bike too hard (like very long hill climb) to not fry your motor. 

That being said the FLX bike does have high temp cut offs and should shut itself off before getting hot enough to fry your motor.

Although we have done hours of testing on a 48v of a flx bike, and have climbed some big hills, there is no guarantee that you will not fry your motor using this pack.

Our advice is to monitor the temperature of the motor with either your finger or even better a temp sensor to make sure your motor is not getting hot to the touch.

We recommend this for advanced users  and enthusiasts only.  If you buy this battery we recommend you post in this forum your results

Understand when you hot rod your bike you do so at your own risk. Luna Cycle and FLX are not respoonsible if you damage your ebike or its components.

 Amp hours and watt hours vs OEM FLX Pack Range Comparison

The Luna Ebike pack is  a 13s4p pack (52 cells) which translates to  48v  13.5ah = 643watt hours. 

The original FLX pack is 10s4p (40 cells) which translates to 36v  13ah which translates to 36v  13.5ah = 468 watt hours

 

What this means is you will get 40 percent more range with the LUNA 48v upgrade pack. 

 

For more information how much  range to expect please read this informative article. 

 

 You can use this in addition to your stock FLX pack, just carry one pack in a back pack when you do extra long rides.

 

EASIEST FLX UPGRADE Ever

We used the same Reention case to make this pack.

Just change the old battery out and click this one in. It's that easy.   

The pack fits perfectly where the OEM pack fit.

AND you can switch back to your stock pack whenever you want.

 

We change the charge port so that you do not inadvertently plug the wrong charger into the wrong battery pack. You do need separate chargers and should only use the charger that comes with this pack. 

 

Top Quality Cells

This pack is made up of the highest quality power density cell in the market which the  Panasonic 3500 GA which has both power and density.

Each cell is made from well known factory Panasonic, and each has more capacity than any 18650 on the market.

 

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.

 

Installation and basic info 

This pack is an easy plug and play replacement to your OEM pack.  You can switch back and forth between the stock and the upgrade pack.  

Less than 1 minute upgrade time. The easiest upgrade ever.
