ProTek’s all-new 2S-4S 4-Battery Parallel Charger Board (PTK-5335) will enable you to charge up to four batteries simultaneously, while balancing the individual cells of each pack. The Parallel Charger Board is encased in an impact-resistant custom-molded plastic shell and is compatible with LiPo, Li-Ion and LiFe batteries. The DC input and battery port are protected with replaceable fuses, and each cell and balance wire is protected with self-resetting poly fuses.
When you need multiple packs charged in a hurry, this is the best option. Plug in up to four batteries of the same chemistry with a standard T-style connector and balance lead, it’s that simple. The Parallel Charger board only works when charging batteries of the same cell count, similar age and similar discharge rates. If those requirements are met, you’re good to let the juice flow.
