Had a thought, but I wanted to know how bad this might be.
Thinking about to batteries on my ebike. One that is almost brand new using 18650s, the other would be a LiPo hobby pack of the same AH rating wired in series. The thought here would be that I could easily add or remove the lower voltage LiPo pack. The 18650 pack does have a bms. I would charge them separately and use a xt-90 series connector to wire them.
The question: How likely is this to cause a fire or destroy components? Would the BMS in the 18650 prevent this from working due to overvolting? Are there other considerations I haven't thought of? If the LiPo battery wouldn't work, would a separate 18650 battery pack work?
