to bypass or not to bypass bms?
If the battery or motor is disconnected then you can''t have electronic brakes. The day we start using mechanical brakes this all changes, but for now it''s safer to risk exploding your battery than to risk not having brakes. Be smart. Have brakes. Don''t fuse your discharge and don''t discharge through the BMS.
Battery bypass : r/Surron
In stock form, power from the battery to the controller must pass trough the BMS. It''s an electronic board on top of the battery that limit the power (amps) and protect your battery. When you do a bypass, you allow the flow of electrical current to "bypass" the BMS and you can get a bit more power (amps) available.

What is a BMS discharge bypass config?
The 2nd bms shows a bms discharge bypass config. The bypass makes this a charge only bms. From research online, this appears to be a fairly common practice in the e skate and other communities. The idea behind this is to bypass the discharge section of the bms to get full power from the battery.

Is it safe to bypass BMS discharge by soldering new wires?
bypassing the BMS discharge by soldering new wires onto the battery poles: is this safe? "ypassing the BMS discharge by soldering new wires onto the battery poles: is this safe" : specifically this is NOT safe, batteries are thermally sensitive.
Why do I need A BMS bypass?
The idea behind this is to bypass the discharge section of the bms to get full power from the battery. They can use a bms that has a lower amp rating but still get the higher amps desired because of the bms bypass wiring. Also an added benefit is the ability to avoid the bms shutting off power and thereby avoiding the not so pleasurable faceplant.
Is ypassing BMS Discharge safe?
"ypassing the BMS discharge by soldering new wires onto the battery poles: is this safe" : specifically this is NOT safe, batteries are thermally sensitive. If you are able to disassemble and check the circuit board in either the battery or the original device it is meant for, there may be some clues to what signals it is expecting.
Is bypassing discharge a common BMS practice?
Your diagram looks fine Bypassing discharge is fairly common BMS practice AFAIK. Yes, this looks great – if you don’t have any accessories.
