This new CSRC paraboard supports both mCP X and mCX/mSR/Proto X connectors and allows you to charge up to twelve batteries at the same time! Because it charges in parallel, you can charge as few as one or as many as twelve batteries of varying capacities at once.
Also great for batteries used in the Parkzone Vapor/Night Vapor, P-51, Ember, T-28 Trojan, Sukhoi Su-26, Spitfire, Stryker, Pole Cat, Corsair, as well as Blade Scout and Nano CPX.
How to use it
The paraboard allows you to connect up to twelve batteries in parallel so that you can charge them as a single larger mA single cell battery (i.e. 1s6p). Battery packs must be of the same cell count (only charge 2S with 2S, 3S with 3S, etc.) and battery voltages must be within 0.1V per cell (0.1V for 1S, 0.2V for 2S, etc.) of all other batteries connected to the Paraboard at the same time. Use a Cell Spy or similar voltage tester to check the voltage of each cell before connecting to the Paraboard.
Calculate your charge rate by adding together the mAh of all the batteries you intend to charge. To charge your batteries at a 1C rate, divide your combined mAh by 1,000 and this will tell you what your amperage setting should be. e.x. (6) 7.4V 300mAh batteries would be: (6 * 300) = 1800 / 1000 = 1.8A
Max Charge Current: 4.8A
