How to Get 24 Volts from 12V of a 25 Battery Group
If you need 24 Volts, you can connect two group 25 batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries. If one 12V lead-acid battery is connected to another 12V lead-acid battery, you have 24V total power output. Each battery must be fully charged and completely isolated from the other before connecting them in series, or there will be damage to at least one of them.
Increasing a Capacity of 25 Batteries with a Parallel Connection
If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group 25 batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities. If you have two 12V lead-acid batteries with 60 Ah capacity and you connect them in parallel, you'll get 12 Volts with 120 Ah.
