Note: This board can do any kind of 4 to 10 strings. Please take a message when you take a picture. We have good configuration parameters to achieve the number of strings you want. Configurable parameters: overcharge point 2.8V-4.375V range configurable, one step per 25mV; Over-distribution 1.4V-2.900V range is configurable, one step per 100mV; When photographed, the above configuration parameters are defaulted. Of course, you can also leave a message for your own parameters. We will configure it for you, but it must be a parameter within the configurable range. Parameter Normal charging input voltage (maximum) Each section 2.80V Charging nominal working current / Maximum working current 15A / 20A Normal charging overcharge protection voltage 2.80V Normal charging over-discharge protection voltage 1.80V Discharge nominal working current / Maximum working current 15A / 20A Overcurrent protection current and delay 60A / 300ms Short circuit protection and delay <500µs Protection board over-temperature protection (temperature & delay) 65°C Operating temperature range -20°C ~ 65°C Balanced starting voltage 2.40V Balanced current 50mA (Energy-consuming type) Static power consumption ≤100μA (Power consumption in sleep state) Working power consumption ≤300μA (Power consumption in active state) Internal resistance ≤10mΩ (Discharge path), ≤15mΩ (Charge path) Size 50 × 45 × 6 mm The following are the factory default configuration parameters: A: 3.7V lithium cobalt oxide battery group: overcharged 4.25V, over-discharged 2.50V B: 3.7V ternary lithium battery group: overcharge 4.20V, over-discharge 2.80V C: 3.2V iron phosphate battery group: overcharged 3.65V, over-discharged 2.50V D: 3.8V high voltage lithium battery pack: overcharge 4.45V, over discharge 3.00V E: 2.4V lithium titanate battery group: overcharge 2.80V, over-discharge 1.80V
