Hi All,
My first post in this forum!!! My name is Kisho and nice to e-meet you all!! Hope you are doing great!!!
I am having trouble with my e-bike battery. The power completely cuts out under a medium-high load. The LCD goes error 006 (low voltage error) and an off/on is required to get going again. The cut out happens very fast around 450w (on LCD). The bike has been going well for about 6 years and has had a controller upgrade to Greentime 500w-600w 30Amp - 48V - 12 MOSFET controller with LCD (had for 7 Months).
Specs: Greentime 30Amp - 48V - 12 MOSFET 500-600w Wiring Controller, Brushless 500W motor (motor wires upgraded), Yosepower 48v 11.6AH Battery (had for 2 years) Battery Link for information.
So, I have 3 other batteries all of the similar specs but from different providers (2x eclipse bikes, 1x eBay) which are about 3 years old now but still strong to handle the full load from the motor without cutting out (but I take them gently now as they are around 80% capacity). But so far states that the motor, controller are running fine (still checked either way to make sure).
So, after 2 attempts of full charge and the battery cutting out while riding, I decided to do a battery test with a constant 75w being drawn out to find the LVC which was around 46-47v. From that, I decided to disassemble the battery to see if any wires or connectors may raise the issue but they all seem to be fine (one image looks like a cell leak but I believe it from the adhesive foam padding). Measured voltage pack directly from the battery which was 54.06v and same on the discharge port that matched.
tired getting measurement of each cell but I think it balances out in series due to the metal plates, but I measured across all the pins on the BMS which the results were as below:
Sorry for the long thread but I hope to clarify all the checks I've done and hope I could hear some advice from you soon
many thanks
