    Kingpan charger voltage adjustment

    Thanks for the info. I adjusted VR2 and noticed the amperage dropped. The charger doesn't have a thermistor daughterboard attached. Sorry, i don't understand why increasing the voltage will give me a cut off voltage of 57.6V (ping sets them to 60 but 59V is ok, 60V is ok too).

    Kingpan charger voltage adjustment

    You are both legends! Now... how to set the voltage accurately without the charger connected to the pack? Trial and error i guess. Hook it up turn it on and slowly adjust trim pot 'til it turns off at the required voltage. Anyway... Thanks very much for your time

    Thundersky battery issue

    Hello, I'd like to start a debate regarding the Thundersky (Winston) battery cells. I have recently been told that these cells will not function correctly when laying on their flat side as the electrolyte eventually settles and exposes the upper plates, reducing capacity. The retailers...

    Aussie battery pack builders.

    G'day, Before i start to buy cells and a tab welder, i thought it best to check on here to see if anyone in Australia is building packs or anyone plan on doing it in future. Maybe we can collaborate and find the best deals and work together. I'm based in Adelaide. Cheers!
