My setup is 250w bafang hub, 36v bottle battery, 11.1v booster pack(homemade 18650 pack with 6 cells in each series), ku65 with 810 model LED
I was about 12 miles into my commute when the power failed. My LED went from 4 lights to 1 flashing light. Now this would indicate the LVC had tripped
But the kits is a 36v one and so is overvolted at 48v thus rendering the LVC useless
I had to cycle last few miles unassisted
At home I tested my batteries. My main was reading 39.5v but my booster only 6.5v. It turns out one of the series has packed up – no biggie I have loads of 18650 cells taken from laptops and they do tend to die on my every 6 months. Just not designed for the abuse I give them !
But what confuses me is that the overall pack voltage would still be 39.5 +6.5 = 46v so that’s still way over the 42v hot off charger the system expects from 36v input
So why did it read so low on the LED and why wouldn’t it go ? I used my spare 11.1v booster as soon I got home and the system worked perfectly again. As it did on my commute again this morning
I’m confused by this ? Can anyone explain this to me ?
