    58V on a 48V controller.

    Yikes... Annoyingly, 3.2v is the highest voltage that can be set on the alarm! Perhaps a solution would be to mount a cheapo volt meter somewhere on the bike that I can see when riding, that way I can keep my eye on it. 43v/12 = 3.6ish v per cell, I'll also be able to see what happens under load.

    58V on a 48V controller.

    Well today I did a five mile round trip, full throttle most of the time and a relatively steep hill to get up. I had cell monitors on both batteries throughout with the alarm set for 3.2V, it never went off. The voltage dropped quickly to 3.8-3.9 per cell but stayed almost constant at this...

    58V on a 48V controller.

    Not sure what type it is, looks like the 1000W version of this: http://www.ebay.co.uk/itm/26-Front-Rear-Wheel-Electric-Bicycle-Motor-Kit-E-Bike-Cycling-Hub-Conversion-/322364987166?var=&hash=item4b0e73571e:m:mfK_XRNN_lMbUi9KjiF4xRA I don't expect the 6800 mAh batteries to last long, but I...

    58V on a 48V controller.

    Hi all, I've got a 48V front wheel hub motor and controller (a cheapo conversion kit). I've been running it for a week or so with two 6S 6.8AH lipos in series. Fully charged this gives 50.4V which drops down to ~45V within a few minutes of use. I guess this is pretty normal for the lipos, but...
