This 52V 17.5Ah battery replaces the original battery of your Dualtron Mini: same voltage, same connectors, same dimensions, to restore the range and performance of a brand-new scooter. It is assembled in our workshop using brand-name 18650 cells (Samsung, LG, or Molicel depending on availability) and a BMS sized for the machine.
When should you replace your Dualtron Mini battery?
Three signs don't lie: a rapidly dropping range (half of the original range, or even less), power cuts or voltage drops during acceleration or uphill climbs even though the gauge still shows charge, and a pack that heats up or becomes unbalanced (a cell fails, the BMS cuts off). A high-quality pack restores the scooter's original torque and top-end performance; on a machine that is a few years old, it is often the best euro spent.

Range or Performance?
This Range version prioritizes capacity and lifespan, with a discharge current adapted to the original controller. If you have upgraded 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.
Made in France, 2-year warranty
All our batteries are assembled in our workshop in France, exclusively using brand-name 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 and charging connectors; the charger is sold separately. Shipping to metropolitan France, Corsica, and the European Union only (regulated lithium transport). 2-year warranty.
Frequently Asked Questions
Does the original charger work?
Yes, if its voltage matches (52V). On fast-charge compatible packs, a more powerful charger significantly reduces charging time; ask us for advice.
Do I need to break it in?
No. We simply recommend a few full cycles at the beginning so the BMS can calibrate the balancing, and to avoid 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).
