6 FAQs about [Is it okay to charge two battery packs in series ]
What happens if you charge a battery in series?
When charging batteries in series, battery imbalance is common. This causes some batteries to discharge more quickly than others which ultimately leads to shorter battery lifespans. In contrast to batteries in series, batteries in parallel only increase the amp capacity rather than voltage. This means you can power your devices for much longer.
How many batteries can I use?
You can use up to two of our Lithium 12v / 24v batteries in series and up to four in parallel packs. You should arrange your charge setup so that each battery in the pack is individually connected to a charger. Batteries should be of the same model, and purchased together at the same time, to ensure they have similar performance characteristics.
How do I charge the batteries in series?
To charge the batteries in series, find a charger with the total combined voltage of all the batteries. However, we recommend you charge each battery individually to prevent battery imbalance. Battery imbalance is when different cells within the pack exhibit different charge levels, capacities, and performances.
Can a battery be recharged by a single Charger?
Batteries connected in series strings can also be recharged by a single charger having the same nominal charging voltage output as the nominal battery pack voltage. In Figure 8, a single 24-volt charger is connected to a 24-volt battery pack. In Figure 9 we see a pair of 12-volt batteries connected in parallel.
What happens if you put two batteries in parallel to charge?
With two batteries in parallel to charge, It will be cut in half not doubled. If you are talking about the Charge current applied from solar with two batteries in parallel, It will be cut in half not doubled. If your MPPT produces 20A into the 2 batteries, it will be felt as 10A into each battery (Assuming same SOC).
Can a group of batteries be connected at the same time?
There are many ways to connect a group of batteries in both series and parallel at the same time. This is common practice in many battery power appliances, particularly in electric vehicles and large UPS systems where the battery packs require large voltages and amp-hour capacities.
