Description of πŸ”‹ LIVISN 4S 30A 14.4V-16.8V Li-ion Lithium 18650 Battery Charger Protection PCB BMS Module (4S 30A)

Main features: over charge protection, over-discharge protection, short circuit protection, overcurrent protection. Overcharge detection voltage :4.25 Β± 0.025V(Stop charging, When 1 of 3 battery out voltage> 4.25 Β± 0.025V). Over discharge detection voltage :2.50 Β± 0.08V(Stop out, When 1 of 3 battery out voltage < 2.5V). Operating Current: 15A (natural cooling 10A, additional heat sink 15A, the maximum instantaneous current of 30A). No part design on the back, can be attached to the heat sink to ensure that large currents to work long hours. Lift Condition:Protecting release the auto recovery, without activation.

Absolute rubbish. Nothing worked properly.

Bought the 20th version of this BMS. Absolute rubbish. If the BMS is working, it must be completely disabled before it will work again. In addition, the end-of-charge voltage was 77.6 volts. So this piece of shit couldn't even balance the battery.

Pros
  • Inspires confidence
Cons
  • Not fashionable

Cheap Batteries, Chargers & Household Accessories

I didn't want to risk my expensive LiFePO4 batteries with a cheap BMS. I hooked up the BMS, cell voltage monitor and the exact smart charger to see if it works. My board did exactly what it was told it would charge. I didn't test for short circuit or over current as my circuit also uses a circuit breaker and it trips first. I repeated the charge test with a "dumb" 15V DC 6 amp power supply and the cells charged to the correct voltage and then the BMS shut off the charge power to avoid over…

Pros
  • Easy to Use
Cons
  • Quick Start Guide
