People, if you do this, put a big diode across each battery. Anode to negative. Otherwise, if one BMS goes open circuit (e.g. overcurrent, overheat), the other BMS will see twice the voltage it was designed for. The diode will prevent this.

6 Frequently Asked Questions about “Cautions for connecting lead-acid batteries in series”

Can a 12V battery be connected in series?

When creating a lead-acid battery bank with a higher voltage, like 24 or 48V you will need to connect multiple 12V batteries in series. But there is one problem with connecting batteries in series, and this is that batteries are not electrically identical. They have slight differences in internal resistance.

Can a battery be connected in a series?

In short, connecting batteries of different voltages in series will work, but damage will be done to both batteries during the discharge and recharge cycles. The more one is damaged, the more the other one will be damaged and both will need replacing long before needed.

Should I use the same battery rating & model?

When connecting batteries in series, the general advice is to use batteries of the same ratings and the same make and model in order to minimize differences in exact voltage and amperage. Note, we say 'minimize', because even batteries coming off the same production line can vary slightly in these measurements.

Why are batteries interconnected?

Batteries are interconnected to increase the battery voltage or to increase the battery capacity or both. Multiple interconnected batteries are called a battery bank. When batteries are connected in series, the voltage increases. When batteries are connected in parallel, the capacity increases.

Can a 12V battery be overcharged?

If the four 12 V batteries are identical, you can treat them as a single 48 V battery, once they are connected in series. Lead acid can be safely overcharged under defined circumstances (current below a threshold, topping up wet cells as required), which balances the batteries.

How to maintain a balanced battery bank?
