Hi, I have an 18s 4p lipo battery pack. It is split into 3 6s 4p packs, which are connected in series.
The chargers I am using are 3 UNRC-UNA9-PLUS. They charge solely through the balance wires.
When I plug one 6s4p pack into one charger, it charges fine. However, when I plug all 3 in and charge simulatenously, I get an error and the chargers stop. If you disconnect 6s4p packs so that they are not in series with each other, they charge fine.
Can anybody help identify why the chargers interfere with each other like this? Is there a simple fix - other than just disconnecting the packs from each other each time you want to charge them?
