iSDT Safe Parallel Charging Board for 4 Batteries 2-8S (XT-60)

Parallel charging allows for multiple same cell count batteries to be connected in parallel to create a single larger logical battery that can then be charged.

With this board you can charge four (2-8S) LiPo packs with same capacity and cell count simultaneously.

About Parallel Charging

1. Only use LIPO/LIFE/LI-ION batteries with the same cell count, NO EXCEPTIONS. e.g: 2S with 2S, 3S with 3S, etc.
2. Preferably, use batteries of similar capacities. e.g.: 500-1500 mAh batteries together, or 1300-2200 mAh batteries together, but not a 500 mAh battery with a 5'000 mAh battery.
3. Use batteries with similar states of charge. Do NOT put a 1/2 full or 3/4 full battery in parallel with an empty battery.
4. Always plug in the main plug first on ALL batteries, then plug in all the balance plugs.
5. Wait several minutes after plugging in the main battery leads into the parallel charge board before plugging in the balance plugs. This prevents high currents from flowing through the balance plugs as the batteries equalize based on their varying voltages upon plugging them in. This is also the reason you want to use batteries of similar states of charge/discharge.
6. Be VERY CAREFUL to plug in the main leads and balance leads correctly. Attempting to plug them in backwards will cause a short circuit and a spark, and potentially damage your batteries and/or your parallel charge board or battery leads.
7. Once all batteries are plugged in together in parallel, wait several minutes (3~10 minutes) for them to equalize their voltages. The farther apart the batteries charge states, the longer you should wait.
8. To determine the charge rate when charging in parallel (assuming the standard 1C charge rate), add all of the battery capacities together, then use that value as the charge current. E.g.: Parallel charging three 3S 1300 mAh (1.3Ah) LiPo's with two 3S 1000 mAh (1Ah) Lipo's would mean that you should set your charger on the 3 cell LiPo setting at a charge rate of (3 x 1.3) + (2 x 1) = 5.9A. Therefore, in this scenario, a charge rate of 5.9A corresponds to a 1C charge rate, and the charger will consider all of those batteries in parallel to be a single 5900 mAh (5.9Ah) 3S Lipo.
9. It is recommended to use a fire-proof LiPo-Safe Charge bag when charging. Place the entire charge board with all of the attached batteries, if possible, inside of the same charge bag. If the batteries are very large, and this is not possible, feel free to separate the batteries into separate charge bags.
