Parallel Charging Board for UMX Batteries

This brand-new paraboard allows you to charge up to twelve lipos with UMX-style connectors at the same time. Because it charges in parallel, you can charge as couple of as one or as many as twelve batteries of varying capacities at the same time.
Perfect for batteries used in the Blade 130 X, mCP X BL, UMX Beast, Mig, Carbon Cub, and Sbach 342!


Merely link the banana plugs and JST-XH balance leads to your SIX lipo charger, plug in the batteries you want to credit the paraboard, program your charger and charge!
The paraboard allows you to link up to 12 batteries in parallel so that you can charge them as a single bigger mA two-cell battery (i.e. 2s12p). The only requirement is that all the batteries be within .10 of a volt of each other before charging. For instance, if you either time your flights or fly till cutoff. You wish to avoid connecting a totally charged battery to a group of released cells, because a quick rush of current would happen.

Calclulate your charge rate by totaling the mAh of all the batteries you mean to charge. To charge your batteries at a 1C rate, divide your combined mAh by 1,000 and this will inform you exactly what your amperage setting ought to be. e.x. (6) 7.4V 300mAh batteries would be: (6 * 300) = 1800 / 1000 = 1.8A

Maximum charge rate = 10A

 As good as any e-flight lipo but....
By Kirk S on December 22, 2018   Verified Purchase

I imagine the batteries are fine, but they didnt come with any velcro to attach them to my plane, leaving me to source some.... These batteries are used in a lot of their UMX planes, so you would think they would include some velcro....
