Hi need help,I have two [Electrobike plus 26 ] folding bikes both are 36v 8ah and a 250wh motor both did work but the battery on one of them the 3 connector were bent and the battery would not locate correctly.so I took the bottom cover off and opened the connectors now it fits well.but it will not work.if I turn the battery on its full with 42v on the connectors but when I turn it on when it's in the bike the lights on the battery go off.if I put the battery from the other bike in everything works so now I feel that the connectors are not making contact on that battery but if they were not why do the lights go off?.I have now made a battery pack with 3 x12v 7.0amp batterys which gives me 36v 7amp to try which I put a fuse in line and on and off switch.I connect the + & - to the connectors on the bike and turn the battery on and nothing happens but there is 40v coming from the leads if I put the made battery on the other bike it will not work.I know that I have not used a bms on the new battery but I still feel it would work,unless on the Electrobike plus you have to have a bms and that why the battery off the bike and the made up battery don't work.
Many thanks for any help and sorry for how long this is.
John
