This is the latest version of ParaBoard with self-resettable fuse protection. The PCB board is made of three ounce copper and the main circuit supports up to 40A current. All the balance ports are protected by resettable fuses (also known as polyfuse).

ParaBoard - XH can be used for batteries with JST-XH balance connectors, such as Gens Ace, Pulse, E-flight, Turnigy, Glacier, and most other modern LiPo packs.

This device is to be used with a balance charger to simultaneously charge multiple lithium batteries in parallel. By this method you can significantly save time on battery charge process.

Principles and practices of parallel charging lithium batteries have been well discussed in the forums on RC Groups. This method has been proven to be a safe and efficient way to charge LiPo batteries, and is widely used RC hobbyists all over the world.

Parallel charging can save you time significantly. If you charge four batteries at the same time, the charge current is four times of that you used for a single pack, and you need only approximately 1/4 of the charge time to charge all four batteries separately. 

Multiple safe ParaBoards (V3) can be connected directly (daisy chained) in order to charge more than four batteries at a time.
