Hi,
I have an 16S Li-ion system with Bestechpower HCX-D131 BMS system in 16S version. The device has standard BMS functionalties, especially protects the battery from overdischarging during use. This means if you run out of juice, it cuts off the system and you can't run the motor until you connect the charger when you reach home.
I would love to have a "one/last chance button" that would activate the BMS once to let me roll slowly home instead of pedalling on my high speed chainrings set...
I think I need one or a few parallel 18650 cells connected to a standard e-bike charger plug through a step-up converter that builds up "some voltage", probably something like 16*3,7= 59,2 V. Then when out of juice, I'd connect this setup to the charging point for 1 second and get some free low speed juice to get slowly home.
What do you think? Anybody tried? Which cheap (a few bucks on aliexpress) step-up would be ok for doing this?
