CUSTOMERS USING BYPASS BMS
If you are NOT using ERT software/programming to handle LVC you can do so manually by monitoring voltage real time via bluetooth app or by using your bikes display.
Use the 8-7-6 rule.
80s is full charge, 70s is middle ground and 60s is getting low.
60 is ABSOLUTE ZERO (cell spec is 2.5v per cell so 50v is actual lvc)
USING 60V AS 0 LEAVES PLENTY OF ROOM FOR ERROR.
So long as you follow this rule you will get years of use from these upgrades.
