Hi guys,
Motor i'm going to use will be 24 volts, i was going to buy 2x 12v 40Ah batterys & run them in series. But i got thinking, the size of these batterys are pretty big (not really an issue with the build i'm doing at mo) but if & when i decide to do another build which is smaller, these batterys may not fit in the hull or be too heavy which would mean i would then have to buy more batterys of a smaller size, so i've been thinking of getting 4x 12v 20ah batterys which are about half the size of a 40Ah & wire them up so I have 24 volts & 40Ah.
Is there any drawback in linking up 4 batteries this way instead of just using 2 batterys or is it fine?
Also when it comes to charging, do i have to charge 1 battery at a time? or is there a charger that can do mutiple batterys (12v 20Ah) at a time?
Cheers!
