Features: This is the new design solution for 1S Lithium recharging board with series connection, it is not the parallel recharging board. The principle is that this series recharging board makes the batteries as battery series batterypack. You can easily use this series board to recharging /storage/discharge with monitoring each cell. It can recharging-up to 6 lithium batteries at the same time when connecting with a balance cable, effectively save your time. As you know, the parallel recharging board have the voltages deviation limited and safety problem. For parallel recharging board, if the voltages deviation between batteries is high than 0.1Volt, so you canot recharging them at the same time due to safety problem. And In parallel recharging, if one of your batteries have problem or short circuits, then it will affect and do harm to others . But it have not the problem using this series board, you can storage your batteries at the same time. So this Series recharging board is better and more safety. Comes with 4.0mm banana plugs to XT60 male cable, which have fine conductivity and reliability, with a strong overloads bearing capacity. Specifications: Material:ABS Battery connection: JST-PH2mm and JST 1.25mm Recharging cable: Female XT60 16AWG silicone cable and 4.0mm Banana plugs to Male XT60 cable Balance cable: 6S 22awg silicone Maximum Current: 4Amp Size:Approx.88mm/3.46''x55mm/2.16'' Package Includes: 1Set 1S Series Charging Board note: Please allow 1mm errors due to manual measurement.
