36V 15Ah E-Twow Battery

This 36 V 15 Ah battery replaces the original battery of your E-Twow Booster V, Monster, Booster S+ and E2-Evo: same voltage, same connectors, same dimensions, to restore the range and performance 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 appropriately for the machine.

When should you replace your E-Twow battery?

Three unmistakable signs: a shrinking range (half of the original range or even less), voltage drops or cuts during acceleration or when going uphill even when the gauge still shows a charge, and a pack that heats up or becomes unbalanced (a cell fails, the BMS trips). A quality pack restores the scooter's original torque and top speed; on a scooter that is a few years old, this is often the best money you can invest.

Range or Performance?

This Range version prioritizes capacity and lifespan, with a discharge current matched 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

All our batteries are assembled in our workshop in France, exclusively using branded cells (Samsung, LG, Molicel). Each pack is equipped with a BMS that manages charging, discharging, cell balancing, and thermal protection. The price includes the pack, power connectors, and charging connectors; the charger is sold separately. Delivery to mainland France, Corsica, and the European Union only (regulated lithium transport). 2-year warranty.

Frequently Asked Questions

Is the original charger compatible?

Yes, if its voltage matches (36 V). On fast-charge compatible packs, 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 at the beginning 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).
