    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 board

    I'm over 50 charges in and no issues with board. Such a great tool, only wish I could get one in with BT2.0!!

    Perfect!

    Awesome 1s serial balance board, very handy for both charging and storage charge. Nice to be able to set it from 1 to 6 batteries, making it very convenient. Great purchase, adds some precision to 1s battery maintenance.

    Awesome for 1s batteries

    This board is just awesome. I tested it on 4 1s lipos. I was able to storage charge them on my charger as a single 4s battery. Before I had to just run my drone to discharge them.
