HI
I want to hear what you people think: is the
BMS or is it the controller ?
I have had a MPII ( I think ) with an external controller and a 15 Ah Ping battery see this tread :https://goldenmotor.com/SMF/index.php?topic=5010.msg29172#msg29172
Last year my
BMS was replaced with this
https://www.pingbattery.com/lifepo4-lithium-batteries/ The Specs are here
https://www.pingbattery.com/blog/whats-new-on-v5-lifepo4-bms-battery-management-system/I have only managed 150 km and have lost all power on 6 occasions. Sometimes after a bump in the road - Unfortunately, I haven’t had a multimeter when cycling. No fuse has ever blown, I have Anderson plugs and am used to have some arcing when engaging them. In these instances- no arcing, and if I disengage the battery’s internal 16 pin contact and reconnect it power have returned on most occasions. I am thinking cold solder or lose connection within the battery making the
BMS cut out- but want to check through the rest of the cabling as well
- Is there any other thing I should do such as measuring throttle - brakes etc. ?
I have been looking tru my wire harness and it is worn´- I will order a new one from GM Canada
