## Description

1.12V 4S 200A Protection Board application for 3.2V Lifepo4 Battery

Review: Works - Replaced the 200ah BMS on a Chins battery
Review: Delivers - Replaced a defective SOK 208ah JBD 200ah with this board. So far it charged at 55 amps, balanced and discharged at 20ah and no problems. UPDATE: FAILURE AT 3 MONTHS AFTER INSTALL. The first 60 days worked well and battery was connected to a refrigerator that pulled intermittent 4ah, charged with a Victron IP 22. Both bluetooth and an led shunt were used to monitor. Checking one evening showed a strange power differentiation between charge and consumption. After case disassembly cells were fine at 13.5 but BMS had no pass thru and a few MOSFETS had zero values tho it still should have had function. No melting or burning is present. Very disappointed as I had hopes this BMS would work in this low demand circuit.

### ⭐⭐⭐ Works, but no documentation, have unanswered questions.
*by J***S on January 31, 2023*

The lack of any documentation is annoying. It appears to have a high temperature cuttoff sensor on a flying lead, but I don't know if it will inhibit charging if the temperature falls below freezing. There is also an unused connector labeled C+ and C- and I don't know what this is for. I've run it just above 100 amps discharging which is well below the 200 amp rating. I've charged at 39 amps without problems. The voltage drop across the unit is acceptable at 100 amps discharge. I did not measure it while charging.
