bought this car for the batteries but theyre at 0.5v
it was built by an Electrical Engineering student from UBC
now i need to figure everything out
had to move it off the driveway but all the batteries are dead and the 12v battery was at 1.5v
poppped the caps and put rainwater in the cells and connected it to 5s7p of 25R
while thats working made a 4s5p of 30Q with copper foil and magnets
disconnected each end of the deep cycles and hooked up the ebike batteries
that got the car moved
checked on the 12v battery, disconnected from the 25r pack, the voltage is coming back but???
motor 9kw continuous

the lithiums are 17s 61v, controller 72v and i was triggering the lvc of the controller with only 2 battery packs to get up a hill, needed 3rd pack to lose the volt sag.
going to try and save the lead acids , 12 lead acids, recycling shop pays $10/battery. im willing to spend $120 trying if not i scrap them and get my money back
back to work
measured the voltage of the 12s and its 12.1v need to get it up around 80v
hooking up 18v to the dead 12v that was 1.5v is working
i wonder if i hook up a 17s 61v bike pack if that will work???
