Range for 25Ah is max 50 km with medium assistance, a bit short...

Havent actually used it yet, but i 100 percent trust its going to be flawless. I previously purchased a battery from this seller before. Love the aluminum body of the charger with built in fan and the 3 prong pc wall cable. Great looking battery love that it seems to be a little slimmer in person.
