This battery is pure gold. Wish I had it before to show how it’s done to all my friends riding gas bikes. With the 80V my bike’s power is just massive. Be gentle, If you don’t use the throttle carefully, you’ll end up riding the moon

Rider's questions

Does this fit into the same place as the old battery or do you need an adapter on top? And how much is the fast charger ? 1 Answer

Hi Dean. It fits without rising anything. We provide adapters to shave off a few mm here and there but you keep the same top cover and locking mechanism. The fast charger comes with a 30% discount when bought with a battery ;)

Do you need to buy the charger seperate ? 1 Answer

John

We provide a small charger free of charge. But if you need a faster option, you can get the UltraCharger 76V version.

Does the stock charger need to be replaced to charge this battery? 1 Answer

John
