My dad and I made an EV (electric vehicle), the problem is that the batteries are not holding a charge as long as they used to. When you have your foot on the accelerator the car's the voltage drops, and when you let off of the accelerator the voltage pops right back up. the problem is that even after the voltage starts to come back up we start loosing amps. we drop from 500A to 150-100A. we had this problem once before, but after charging it all the way and letting it sit overnight, we observed that the voltage had dropped some. so we charged it completely again. we did this about 4-5 times each time the change in voltage was less and less. Then it ran great. but that does not seem to be working this time, and none of the batteries are that old.
Anyone have any Ideas, if you need any more info don't hesitate to ask.
Thanks
