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 ๐Ÿ˜„

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 ๐Ÿ™‚

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 ๐Ÿ™‚

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 ๐Ÿ˜‰

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

Over 3500 units sold! 

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 any other of 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!

    Every Whoop pilot needs this!

    This board works perfect for my Whoop and 1s Toothpick batteries! I love being able to charge any number of batteries from 1 to 6 without worrying about the voltages being the same (just be sure the batteries are all the same!). I soldered some Micro Deans into the BT2.0 holes since thatโ€™s what I use. I also 3D printed the cover for it. Mine came with the foam but it wasnโ€™t attached yet which was awesome because it made it super easy to solder in the connectors!

    Nice board .

    Designed to last. I like the use of jumpers, If I lose a jumper no problems. Good price.

    Highly recommended!

    What an awesome product! A great board for taking care of my 1S LiPos. Storage charging have never been easier.
    Quality components and great build quality. Thank you for making this available!
    The only regret I have, is just ordering one board. 2 boards would have been perfect for a dual charger ๐Ÿ˜ƒ
