So, im trying to figure out how to wire in an external battery for my computer electric scooter for more range. I messaged the manufacturer but only got a concluding message of the factory workers having faith in me. No specific information provided to me as I requested. All I see are 2 sets of wires coming out of the battery, 1 for each controller (my scooter has 2 wheel drive). I can’t be for sure without taking off the green wrapping. I’m pretty sure it’s what I have in my diagram. Currently the only way for me to put another battery in parallel without affecting the original battery is shown in my sketch. Would this work?
