What are the issues with mixing LiFeP04 batteries of different

The issue with connecting different packs of different capacity is eddy currents on the buss bars connecting the packs. If there are current measurement devices, their placement may influence the accuracy of their readings. In other words the flow of current between the batteries should not be counted in the Amphours going into or out of the consolidated pack.

6 FAQs about [Connecting lead-acid batteries with different voltages in parallel]

Can lead acid batteries be connected in parallel?

Lead-Acid Batteries can safely be connected in parallel, provided they all have the same state of charge. So you should make sure that each of your parallel banks is fully charged before connecting them together. It doesn't matter if the parallel banks don't all have the same capacity, as they will share the load accordingly.

How to connect batteries in parallel?

Connecting batteries in Parallel is normally performed to increases capacity. This can be done by connecting the positive terminal of the first battery to the positive terminal of the second battery. Likewise, the negative terminal of the first battery is connected to the negative terminal of the second battery.

How to connect two batteries in parallel using diodes?

The diagram below shows how to connect two batteries in parallel using diodes. The anode of Diode 1 is connected to the positive terminal of Battery 1, and the cathode of Diode 2 is connected to the negative terminal of Battery 2.

What happens if two batteries are connected in parallel?

When two batteries of different amp-hour (Ah) ratings are connected in parallel using diodes, the battery with the higher Ah rating will charge the other battery. The amount of charge that flows from the high Ah battery to the low Ah battery is determined by the difference in their Ah ratings and the efficiency of the diode.

Can you mix batteries with different AH in parallel?

You can absolutely mix batteries with different Ah in parallel. In fact, it’s often recommended to do so because it can help balance out the voltage and current between the two batteries. The only thing you need to be careful of is making sure that the total Ah of the two batteries doesn’t exceed the capacity of your charger.
