    BATTERY PROBLEMS

    Well after 5 Hours+ stuffing around, recharging & re-balancing the battery. The problem has gotten worse. Its like there's a hole in a bucket that drains out faster than it can be filled but if you stop the hole it will fill up again. MARK???.

    BATTERY PROBLEMS

    I'm having problems with the recharging again. I balance out the cells then put it on to recharge but had the same problem of the fist cell in the pack going to a higher charge than the rest before the charger light went to green. So I went back to the IMAX B6Ac charger to increase the Voltage...

    BATTERY PROBLEMS

    I moved the watt meter to where I could see it whilst riding & even though the battery reads as 41.2V fully charged it draws down power really quickly so within minutes the watt meter is reading 35V or less. Then after giving the battery a rest the power reading goes back up to just under the...

    BATTERY PROBLEMS

    I can't do balanced charging because there are 10 cells in the battery pack & the charger only does 6 cells max + wrong connectors. The battery pack is a 36V 12A I think LiFe ??? What I don't know is how long to leave each cell on charge for & at what amps to set the charger to. I can alter the...

    BATTERY PROBLEMS

    Here they are 999zip999 . After I recharged the battery the reading was 41.26V. With the motor running in the stand the watt meters readings were 117Ah 5.1Wh 29.96Ap 38.80Vm & 901.2 WP if the readings are different under load will have to wait till I relocate the watt meter to the handle...

    BATTERY PROBLEMS

    Well it seems that you've all gotten bored with answering my posts or there's an unwritten rule about not going beyond 2 pages. I balanced all the cells to 4.08V & put the pack back on the A2B Metro. It took of really well, I turned right to go up the hill & it cut out F***. Since I still...

    BATTERY PROBLEMS

    I've just seen a video on you tube about altering the settings on a ( IMAX B6AC+ charger) specifically about the Capacity cut off settings. The default is 5000mAh My battery is supposed to be 37V 12A. Does this mean that the Capacity cut off should be re-set to 12000mAh. The demo also...

    BATTERY PROBLEMS

    Now you've got me confused d8veh unless you actually found my lost post then I apologize. The one you mention listing the Voltage cell by cell do have the low value cells listed but I have the decimal point in the wrong places. It's possible that I made a reading whilst the charger was on...

    BATTERY PROBLEMS

    Well fellow " Spheroids " after drawing down the power on the highest voltage cell and then re-charging the pack all the other cells are now at between 4.0 V > 4.02 V except for the original high cell that still has the highest charge of 4.12 V. Should I ( A ) keep on de-charging the high cell...

    BATTERY PROBLEMS

    Sorry I don't know the current drawn from the battery. I haven't seen that info anywhere & it isn't in the A2B Metro print out. All I can tell you is that the standard battery used in the A2B Metro is 36V 10A but I've seen it listed as 36V 11.2A as well. I will draw power from the higher 4.1V...

    BATTERY PROBLEMS

    It was sold to me as a LiPo4 36V 12Ah battery that worked fine that had gone through 300 cycles. Also how do I test the charger that came with it to ensure that it isn't the problem. If so is there a charger that I should get that will work an a range of batteries ?. MARK???.

    BATTERY PROBLEMS

    As they say a picture is worth more than this battery. As you all can see this is what it is. 10 lithium cells with no obvious damage and not holding a charge more than 39.7 Volts. Individual cells charged between one at Max 4.1V to Min 3.92 Volts. I've obviously had the battery on charge...

    BATTERY PROBLEMS

    I still don't know how this all works because I'm re typing this because my first attempt went to another place. I hope that this one does better. Anyway I De-boxed the cell packs which are in a 3 X 3 X 3 X 1 cell configuration. Going top to bottom per cell pack the left to right the voltage...

    BATTERY PROBLEMS

    Thank's for the responses I expect i'll get better at doing this & get to know all of you better over time. I hope. Anyway I de-boxed the cells & put them on a multimeter. They range in charge from 3 X 39.3V 2 X 39.6V 3 X 39.7V @ 1 X 4.10V so there is a range of charging differential of...
