What is it and what it do?

Are you sick and tired of cheap 1S lipo chargers with limited functionally and often inaccurate calibration?

Do you wish you could use your good 4/6S charger to balance charge/uncharge/storage or even check internal resistance?

Well me too πŸ˜„

That’s why I developed this balance charging board that would allow doing just that!

And unlike the dumb balance wire looms that only work when all of the plugs are used,

I’ve added a jumper so that you don’t have to populate all 6 ports to close the balance circuit.

Just place the jumper the number of lipos you want to charge and that will make it a 1 to 6S lipo to your charger!

How is it made?

With love of course πŸ™‚

But also with the most rigorous standard for safety and quality.

  • The PCB board I designed from thick traces, copper filled on both sides for thermal dissipation
  • The VIN and balance leads are assembled from 100mm, silicone wires, and genuine Amass XT60
  • It comes with extended, red jumpers (one extra as a spare in case your dog eats it) for easy swapping cell count
  • And the final assembly and QC performed by yours truly, before getting packed by my lovely wife πŸ™‚

In other words, I’ve ironed down every detail with the help of valuable community feedback to bring you the best charging device for your whoop lipos

It is not a hastily tossed together cash-grab.

It is the result of several unsatisfactory iterations, samples and prototypes that I wouldn’t offer if I wasn’t 100% happy with.

Don’t trust me? here’s proof πŸ˜‰


But don’t take my word for it! Here’s what pilots think of it on my distributors’ websites!

About the BT2.0 Version and other connector types:

Preassembled BT2.0 is currently not an option anymore due to supply issues…

All boards however come with unpopulated BT2.0 footprint so you can solder your own

This means you may also solder on your own connector to these unused pads!

Add your own XT30, XT60, Pico 1.25, or hell even add another PH2 and make it a 6S 2P board so that you may charge up to 12 lipos at a time!

Note: You will need to tear out the backing tape for that; I recommend applying heat from a hair drier to soften the adhesive, or 3D printing yourself the back enclosure with a neat little slot to store your spare jumper. Just go get the model from the download section πŸ™‚
