4S 12V 14 8V 30A Lithium Protection Review

I used the included thin wire connector for the monitor/balance connections and soldered an 18 AWG wire for the B-, B+, P- and P+ points. At first I thought the BMS had failed because all my connections were correct but the output would not turn on. Then I remembered that some BMS don't restart until they detect the charger, so I plugged in my 16.8v charger. This worked to reset the BMS and the result was reliable. I only use this with a 20w load, max around 1.5A and it's been great.
