This is charge / balance board for the Blade 130 X, MCPX BL, and UMX batteries from Blade / E-Flight. This is used to charge up to 6 batteries at once in parallel. To calculate the proper input voltage simply choose 1-6 2S batteries with the same mah, and add the mah's of all the batteries together. For example if charging 4 2S 450mah, you would set the charger to charge 1 2S 1800mah battery. We recommend always using this with a balance charger and the battery lead plugged in.
