Cell Count

4-20 cells

Balance Resistor Heat dissipation

Maximum 4W with heatsinks and active cooling

Much less than 4W without heatsinks and active cooling

Cell Voltage

0-5 volts

Charger Current

Maximum 16 amps as limited by G5PZ

Load Current

Maximum 10 amps as limited by STD12N60DM2AG

UART Baudrate

Maximum 20 Mbps as limited by TLP2770

Temperature

I am not equipped to test the low-temperature rating although I can say the board begins to smoke at around 150C and chars at probably more than 400C.

Humidity

Do not get the BMS wet at all unless with silicone conformal coating.

Characteristics

Measurement Accuracy

Depends on charger noise, ADC data rate, and temperature as determined by: INA149AID, ADS1248IPWR, MAX6225ACSA+
