Charge four single-cell lipo batteries simultaneously using a regular hobby charger. This top - notch adapter is crafted with the best materials and meticulous attention to detail. It features the finest plugs, thick wires, and a high - quality silicon coating. Caution: When parallel charging, it's advisable to keep all battery packs at similar voltages. Avoid having a fully discharged and a nearly charged pack on the board at the same time. Instructions: First, plug the cable into the charger. Then, connect four discharged batteries. Charge at 1S voltage and a combined 1C current. For example, if you have four 500mAh batteries with a combined capacity of 2000mAh, charge at 2A (1C charge rate for the combined pack).

Using this 4 - way parallel charging harness cable is easy. First, take the cable and plug it into your regular hobby charger. Next, connect four single - cell lipo batteries that are discharged. When it comes to charging, set the charger to 1S voltage and use a combined 1C current. For instance, if each battery is 500mAh and you have four of them (total 2000mAh), charge at 2A. Important thing to remember is that all the battery packs should be close to the same voltage. Don't put a fully drained and an almost full battery on the board together. As for maintenance, keep the cable in a dry place and check the plugs regularly for any signs of damage. If you notice anything wrong, stop using it and get it replaced.
