In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.
Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage.
Likewise, the negative terminal of the first battery is connected to the negative terminal of the second battery. When charging multiple batteries connected in parallel, batteries in the string will receive the same charge voltage but the charge current each battery receives will vary until equalization is reaches.
When batteries are connected in series, the voltage increases. When batteries are connected in parallel, the capacity increases. When batteries are connected in series/parallel, both the voltage and the capacity increase. Single battery. Two batteries in series. Two batteries in parallel. Four batteries in series/parallel. Four batteries in series.
Ok, so wiring batteries in parallel of different voltage is bad because the batteries try to equalize voltage with high currents essentially by discharging. The thing is, even among batteries of the same type, the voltage is slightly different. How far apart do the voltages have to be that I should consider not paralleling them?
Flow batteries and other chemistries. These are commonly available in 48V. Multiple batteries can connect in parallel without any issues. Each battery has its own battery management system. Together they will generate a total state of charge value for the whole battery bank. A GX monitoring device is needed in the system.
