Here's the well-known series charger on the market, by out pals at fractal!
Make sure you read the user's manual
Here's what Fractal has to say about it:
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 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!
Want to charge BT2.0s? just grab a set of these adapters :)
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
- 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 🙂
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.
