    Nickel strip current question.

    I can see where it says 4.3 amps, but for what length? How do I calculate if I am within specs for the given configuration since it's not just a width x length but is a parallel connection of 6 batteries and 14 in series. That's the reason I am asking, I have looked at this graphics before and...

    bluetooth BMS?

    I have a question to Smart BMS owners about balancing. Let's say I set BMS balance voltage to 4.05V but charge the battery to 4.2V, is it going to always bleed down all cells to 4.05V or is it going to balance as long as it's charging? Either way if charger will be set at 4.2 v per cell BMS will...

    Ideas about charging batteries

    Allright, I think I came up with the solution. Buy a charger that would still bulk charge to 4.05 x 14 = 56.7v and charge them off the bike only when going for longer rides. Sounds like a good compromise.
