    Help! battery needs repair

    Lol....An i must have done 70 recharges easy. ordered some anderson connectors.so i can insert my watt/volt etc meter into the circuit. not chopping off the andersons the battery/motor came fitted with. ive got one of these ive been using as a display on my wifes old bike.

    Help! battery needs repair

    thanks nealh. i do have an identical lcd display on my bbs01 i can swap over, to test the cutting out problem kirsten mentioned she had earlier in this thread.i also have a couple of those voltage displays u mention. ill try an rig one up. when this issue first arose many months ago and i...

    Help! battery needs repair

    update. adjusted charger to charge cells to 4.05v. all at 4.05v 24hrs later all 4.04v several days later all still at 4.04v. used hot glue to make sure bms socket doesnt work loose.think all the pins are making good contact. Optimistically set off.pulling high amps on cpl hills early on was...

    Help! how to manualy discharge individual cell groups via bms block?

    nealh to the rescue again,thanks mate this will save sooo much time. theyre all pretty much the same ,just two higher. Then i can see how it balances up with the charger set for 4.05v which they can all reach. After that i can monitor how evenly they charge/discharge over the weeks. if i can...

    Help! how to manualy discharge individual cell groups via bms block?

    Hi. i know how to manually balance cell groups with a mobile phone charger. But to save a huge amount of time . Can someone tell me a method of bleeding some charge off say 2 groups rather than adding to 12. For instance,maybe a bulb with a couple of wires soldered on? and would it be attached...

    Help! battery needs repair

    just checked the vr4 actually marked vr2 (the vr4 marked spot next to it is unused).yeh ...its fully adjustable.i didnt bother seeing how far it went, but several volts either way in .1 increments by the looks. the meter charge current i found is 3.15 amps at the moment so left it alone.

    Help! battery needs repair

    thanks for all the help nealh ill try those suggestions on adjustment out today.ive still yet to do the test to see if the cells/which cells self discharge, after being fully charged. on that note all batteries lose a bit of charge with storage.im assuming its just it shouldnt be a noticable...

    Help! battery needs repair

    Hi nealh,It eventually went out again. could be some cell groups lost a little charge over days sitting around causing imbalance to return.i notice the display shows the voltage is holding tho. So u think the lower 2.5Amp charge current (mines 5Amp)combined with setting to only reach 4.05-4.10...

    Help! battery needs repair

    hi nealh ,i get that. My question tho is Earlier you discussed that it would be better if all the cell groups were charged to what the lowest could hold .Rather than higgledy piggledy final voltages. But It sounded as if you were then saying it wont make any improvement to performance. So im...

    Help! battery needs repair

    thanks for that explanation nealh. regarding your second sentence, is it worth getting one of these chargers after all then and trying to get all cell groups to 4.1v? would it make any difference compared to the charger i have taking some to 4.20v whilst others may be 4.05 or 4.08 etc. my finger...

    Help! battery needs repair

    hi nealh. So if i buy say the 2.8a model i assume it will charge slower than the 5a charger the battery came with.thats fine. How do u set it up tho, to ensure each cell group only reaches a say max of 4.08v or 4.10v. do you have to multiply this by x14 and then set the HLG to that 57v odd, or...

    Help! battery needs repair

    Yes good point nealh would explain the randomness. i can see the female connectors undersides are exposed luckily. i can try press them tighter.

    Help! battery needs repair

    hi kristen.i have no one to try this, but i do have an identical display the latest version 850c. i ll try it but i think the voltage sag is more likely the battery deterioration. some cell groups are unable to charge beyond approx 40.08v while others can reach 42v. Perhaps they sag worse as...

    Help! battery needs repair

    thanks so much nealh.yes a typo. im thinking if the cell banks can all even out around 41.0v then all is not lost. one thing bothering me tho,has been a few cut outs requiring the bms plug pulled out and re inserted to get the bike going again.This was when even the lowest cell groups should...
