In order to charge the battery he MAY be able to use a large 36V battery d is plugged into the charge port of the ebike. To determine if this is feasible would require a schematic. Because these batteries have so much power one cannot just connect two of them together as this could create a very unsafe condition as described in the video. | |

| Mar 23, 2020 at 13:13 | comment | added | Christian | That is correct, I run the battery out faster than it can recharge, and I’ve seen the consequences first hand when the battery dies and I charge with my battery pack while riding. But with my normal usage, the battery dies in about 3 hours. It takes about 5 hours to charge. I reckon if I could keep it plugged in all the time with a battery pack that’s big enough, I could drain the original battery slowly enough as to give me 5 hours of continual use. The problem is that my battery pack is too small, and I can’t realistically keep it plugged in all the time, because it’s not dedicated | |

As this answer explains, even if you could theoretically recharge your bike batteries with external, they won't be able to charge them fast enough to be practical (unless you don't mind sitting around for hours not being able to ride while you wait). | |
