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 😄

That’s why I designed 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’re planning to charge and that will make it a 1 to 6S lipo to your charger!

How is it made?

With love of course...

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
  • The jumpers are encased in a custom-designed, 3D printed connector that keeps foreign objects away, and forbids the bravest of you to attempt plugging the lipo in the wrong place
  • And the assembly performed by yours truly, with testing on each unit.

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.

Great Whoop Charging Board

I bought not one but two Fractal Engineering Whoop Battery Series Balance Charging Boards. I like the looks, circuit designing, quality soldering, performance and reliability. So far both boards are performing up to my expectations. I Love this Product! Great Work People. I can now safely charge up to a dozen tiny whoop 1s batteries at a time.
Thank You,

Works as intendend

When you learn how to properly charge with it i get a perf charge using even just a isdtq6 mini

Awesome 1S charging solution

If you fly 1S, you're going to need to put your batteries at storage charge at some point. This is an excellent solution to get up to 6 done at once. Plus it's a series board, so you don't need to worry about your batteries being far apart from each other. Our little 1S batteries dont post too long with the abuse we give, but at least with this board, you can make them last a lot longer.

Where have you been

I've been looking for a way to charge, discharge and to put into storage my 1S lipo batteries. And the fractal engineering serial board works perfectly.
