    That Arduino thing to keep the batteries alive. How to set that up? Been looking for that for years now and no one has been able to come up with anything remotely useful so far.

    Amazing stuff! Comment for the algo, but I wouldn't call a 72v battery with 1800w continuous "high performance" lol. I'm currently making a 72v battery capable of 10000w continous and 18000w peak, now that's high performance lol

    Whats gonna hapen if i conect 2 battary with hout bms ?

    1800watt is like 3x the power I can output

    how does this work for an e-sccoter like JC motiv frame on a 60V 3500W motor? is it based on the specs of the controller or is is based on the capacity of the motor or both?

    How do u charge it with the bms at series can u get a 72v charger or a 36v

    Those output contacts on the inverter look spicy as fk lol why not a true female connector for safety?

    I have an E-Bike battery I want to use on a new controller. How did you use the Arduino to keep the battery on? Mine turns off with the new controller whenever a load is added. It has 2 wires that go to the old controller.

    i am totally new to voltages and amps.I have a 96v lithium Lpo battery is 39 volts now. i try to charge but it wouldn`t take the charge. so how can i jump start the 96v battery. is it possible to use a 72v lithium to jumpstart with a lithium charger?

    great video! thanks for the info.

  11. Avataaar/Circle Created with python_avatars Martha Mryglod says:

    As far as I understand battery packs, you can series connect these after the BMS to deliver 72v to the load. You will then have to charge each independently of each other as 36v power packs.

    Hey stop touching electronics with bare hands. You are causing ESD issues
