It's an emergency cable on the latch that opens it bud.
Someone on YouTube claims that putting 5-12 v DC to the wires to the battery lock opens it but that doesn't work on mine.

Yes, The Youtube Channel Starting with the word
Sherlock Ohms, I watched his videos, but isn't very helpful there. When I send in 9 Volts through the connection, nothing happened. I tried every single combination that I can think of on a spare latch and it did not work. That is due to the thing using CAN BUS Protocol or similar, therefore correct data (key) needs to be sent to the latch (lock) in order for the microcontroller to process the data and unlock the latch. I got myself in through the bottom, there is a white nub, just grinding a medium sized square does the work, but if possible I should have slim jim it, but I will try that when I have a chance to see if that works. I might also try a soda can and see if that works too.
Edited Again: Slim Jim And Soda can didn't work on my end because the gap is too small and the latch is shielded.
So what I know, is:
[*] A
14S BMS should be used on the new batteries, but there is currently no wiring diagram or step by step for wiring the 14S to the chunkier batteries.
[*] Mine Current Project is a Lime Gen 4.1, So some functions may differ than Gen 4.0 but is relatively the same.
[*] To Remove AND Reuse their Proprietary Screws on the wheels, Purchase and Use an
IRWIN 3/4" - 19mm Extractor Socket as it doesn't cost that much.
[*] Their Motor, Just like the Bird 3, is garbage, consider purchasing your own universal brushless motor from a reputable source. Just make sure the dimensions of the universal motor fits into the baseboard of the scooter.
[*] I am still figuring what is throttle, brakes, hall wires, motor wires, etc and it is taking a while on my end, so gotta get my multimeter out if needed.
[*] Since the scooter is missing some hall wires, external mods may be needed to the back wheel to prevent overloading the throttle and allowing the scooter to handle steep hills and/or two-three people. If you don't want external mods, I would recommend putting a resistor to the throttle connections (Blue) to not overload the scooter and make it shut off.
[*] Most of the learning on my ends comes from modifying the Bird 3, so check that out and apply the concept to this scooter.
(Edited: You can even have a setup where a switch can control flow to two separate resistors. One is normal speeds of 20-25 mph, or city speeds of max 12-15 mph.)
[*] Charging is different when their BMS is replaced with one from aliexpress, so figure that out and make sure it's wired right, where I have next to zero electrical knowledge to know, but I know how to strip, solder, and cut wires.
[*] Since the gen 4.0 and onwards, their batteries are swappable, so carry more to increase total scooter runtime.
If you have specific further inquires feel free to pm me. I hope this helps those that need it so those can return the favor and make e-scooters great again.
