If you have more than one battery, they need to be wired together in series or parallel. We increase the voltage in series. We increase the amp hours in parallel.
for example: – if we wire 4 x 100 amp hour 12v batteries in series, we will have a 100ah, 48v battery bank. –

if we wire 2 x 100 amp hour 12v batteries in parallel, we will have a 200ah, 12v battery bank.
