Our main charge leads are constructed from the highest quality materials to ensure that you get the best connection possible every time you charge your batteries. This unique design serves as both a charging and balancing cable for your 3S JST-XH battery pack, allowing you to safely charge and balance your battery directly through the balance lead, without using the main connector. Connect to your battery with the JST-XH connector, while at the charger end you have 4mm banana plugs for the main port, and a standard 3S JST-XH balance connector for the balance port. Top-quality silicone wire gives you the flexibility you need to easily get everything connected.
