I'm considering upgrading my son's 12V lead-acid scooter with 36V lithium battery pack (with BMS) that I'll make myself. I know of a kit out there that someone in the US makes. I've seen an article or two out there (| Details | Hackaday.io) that discusses mods to bypass the current and voltage safety circuits on the Razor motor controller board, but that was back in 2014. You know of any controller mods or drop-in replacement controllers for these scooters? I have some extra lightly-used Lithium-ion batteries (18650, Samsung 2600 mAh, 5.5Amp) ready to build a pack for it. I have a background in electronics, not an engineer, so I would welcome any suggestions.
