Was sick of driving the car for short trips (<5km), and it just so happened that Ninebot had slashed prices on one of their China-road-legal scooters.
1890 yuan (265 USD) later, this arrived:
Rides great (even with no front suspension) and does 35 km/h (22 mph) on flat ground, but range is abysmal
The 48V12Ah pack is only good for 30km, and worst of all it's using a proprietary BMS, proprietary signalling and connectors, so a drop-in replacement is out of the question.
I can, however, buy an identical 12Ah pack from the same battery OEM which has a built-in BMS, but it doesn't "talk" with the bike controller and the pack only has power wire outputs. (+ve and -ve).
So here's what I'm thinking: charge both packs to 100%, and splice the second pack into the first pack's +-ve & -ve wires. The bike only talks with the first pack, but both packs would be in similar condition. Thoughts on this approach?
