It is normal to charge lead-acid batteries in series. As they are used, the cell voltages will change, which is why they are not charged in parallel. If they were charged in parallel, the one with the high voltage wouldn't get much current, and the one with the low voltage would get too much current.
It would also be a good idea to use a charger that adjusts voltage to maintain a constant current. Typical lead acid batteries can be charged at 0.1C (a 1Ah cell can be charged at 0.1A). A 'smart' charger will also make balancing the cells much easier.
In general, it is best to connect batteries in series because this increases the voltage while keeping the current the same. However, there are some advantages to connecting batteries in parallel. For example, if you want to increase the current without changing the voltage, then connecting batteries in parallel is the way to go.
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.
Wiring batteries in series allows for higher voltage outputs without needing additional batteries. This setup is simpler and often more cost-effective due to fewer connections required. It’s ideal for applications that demand higher voltage levels from lower voltage batteries. Wiring batteries in series offers several benefits:
When it comes to comparing the safety of batteries connected in parallel versus series, there are important factors to consider. In a parallel connection, each battery maintains its voltage while increasing the overall capacity. This setup can be safer because if one battery fails, the others will continue working.
