This 72 V 40 Ah battery replaces the original battery of your Nami Burn-E and Burn-E 2: same voltage, same connectors, same dimensions, allowing you to recover the range and behavior of a brand new scooter. It is assembled in our workshop using branded 21700 cells (Samsung, LG, or Molicel depending on stock) and a BMS sized for the machine.
When should you replace your Nami Burn-E battery?
Three unmistakable signs: a shrinking range (half of the original range or even less), voltage cuts or drops during acceleration or on hills while the gauge still shows a charge, and a pack that heats up or becomes unbalanced (a cell fails, the BMS trips). A quality pack gives the scooter back its original torque and top speed; on a machine that is a few years old, this is often the best money spent.

Range or Performance?
This Range version focuses on capacity and lifespan, with a discharge current adapted to the original controller. If you have changed your controller or are looking for sharper acceleration without power cuts, check out our Performance batteries (high-discharge cells, Bluetooth BMS) for the same model.
French manufacturing, 2-year warranty

Delivery in metropolitan France, Corsica, and the European Union only (regulated lithium transport). 2-year warranty.
Frequently Asked Questions
Is the original charger suitable?
Yes, if its voltage matches (72 V). On packs compatible with fast charging, a more powerful charger significantly reduces charging time; feel free to ask us for advice.
Is a break-in period required?
No. We simply recommend a few complete cycles initially so the BMS can calibrate the balancing, and avoiding storing the pack at 100% or 0% for weeks.
Can I install it myself?
If you know how to open the deck and handle power connectors, yes: the battery arrives with its connectors ready. Otherwise, our workshop offers installation (installation package).
