Before you buy any bike and want to put a rear hub on it make sure the nut of the rear hub can fit with some bikes they put derailleur so close to the axle that you can't get a nut on it.

Re: How to check the condition of a battery?

You can find automotive-grade lithium batteries from scrap or used electric cars yes you know it's based on Sweet Summer very easy to put together some are more difficult. But lead is an old technology that works but wears out quickly. Basically lead is dead.
