Just last week I read somewhere in here somebody commenting about buying a trip unit for one of these MCB but for the life of me I cannot find that tread.
Just bought one of these and would need a trip coil to make it fully functional.
ICR18650J and ICR18650H, recovered from electric scooters GPS modules. Tested like new on Lii-500. Charged to 4.2V and rested for a full month to discard self dischargers (none by the way). As of right now 373 units are available but many more in teting line.
120 per 100 units, buy more get...
