is regenerative braking safe to use with sla batteries? are there any potential problems that i need to be aware of?

Not exactly, but sort of; in that if the batteries are already charged to full voltage, more current thru them simply increases that voltage (and they are less and less able to pull down the regen voltage to their max voltage), and if that's more than the controller can handle....poof!friedwires said:so i guess,with fully charged batteries the regen current has nowhere to go but to the controller,which then overheats,melts solder,fries components,etc.
I stopped making the list; it was discouragingly longer than the first three Dune books. :lol:i'll chalk this one up on the list of lessons learned the hard way. oh shit! the list is full,i'll have to start on another page
Well, hold onto the carcass for parts/etc., later on you may start learning to fix them and want some spares. Or someone else will want such a carcass for something.i gave the board a good visual with a loop,and could'nt find any stray solder or bad joints,i also gave it a thorough blow with 120psi.then gave it another try on the scooter and the same thing happens.im gonna use the controller from my kids e-bike to make sure everything else checks out before ordering a new one.
