My son's gasgas e12 only lasts about 20mins now, it's a year old and I'm guessing the batteries need renewing.
It's the 36v 16in the model, I can get the same 3 batteries but would rather upgrade if possible, I've read some of
these suggestions for the oset bikes does anyone know if the same can be done to the gasgas e12, obv I don't want to fry the motor.
Also if I was to upgrade to lithium batteries, what's the best size, AH charger etc?
