This is the ProTek R/C 1S 12-Battery Parallel Charger Board. Do you have a lot of micro flight batteries to charge? The ProTek R/C Parallel Charge Board will charge up to twelve 1S LiPo flight batteries simultaneously. Six charge ports are compatible with MX connectors (also known as pico or ultra micro), used on the mSR and other ultra micro aircraft. Six more charge ports are included featuring 2-pin JST-PH connectors found on Blade, E-flite and ProTek R/C batteries.   

Your battery charger must be compatible for LiPo chemistry and the parallel charge process only works when charging batteries of the similar age and of similar discharge states. As long as these needs are met, plug in your 1S batteries to the Parallel Charge Board and let the juice flow.

Works just like it should. Great for SCX24 batteries. I've got two of these and happy with both.

Works great, however you can only charge 6 batteries of one type at a time and there is no way to daisy-chain multiple boards.
