Hello everyone, I have a Sun Electrolite Ebike with a 250W Bafang motor/controller, 36V 10AH battery. My problem is the system, (controller/LED power indicator) seems to misread the battery state incorrectly, after fully charged ( to 42.5V) the LED display is at the 1st blinking red position, (meaning it's almost out). So far I've used a DMM and found 42.5V at the LED circuit board, I then used an incandescent 20 watt bulb to manually drain the battery to 32V then recharge back to 42 so it might "learn" the correct voltage, no help. I also rigged a DMM to check battery voltage as I ride, no unexpected voltage sags found. The battery has it's own LED display on the rear and it shows 100% charge as well. I take it there is no adjustment for these systems, I'm curious if I can buy an inexpensive controller and somehow make it work with this setup. Here is a link to the LED "display sensor" as they call it, http://www.jbi.bike/site/product_detail ... mber=69342
I'm not sure if this is feeding bad information to the controller or vice-versa. I can use the bike but at reduced range since the system shuts down into battery protect mode much too early, any ideas/advise greatly appreciated.
