This may sound a bit of a silly question, but currently I use one of the small 12V 7Ah sealed lead acid batteries to charge my lipos with (via a lipo charger) - but I only get about 3 charges before the 12V has dropped too far.
...so the obvious solution is to buy a 12v car battery (about 70Ah).
The question is; will I be able to charge the 12V car battery with the same charger that I use to charge the 12V sealed lead acid?
As I understand it a car battery is just a lead acid battery? So same technology and same voltage just higher Ah. Will I blow myself up if I use the small 12v lead acid charger on the big 12v car batt?
Thanks
