1. Product advantages: BMS can reduce the number of strings, be compatible with other batteries, with a minimum of 2S, support extended series and parallel efficiency.2. Applicable batteries: 3.7V battery pack and 3.2V battery pack. Balanced type: inductive active energy transfer.3. Balance efficiency: 92%. Balance current: 800mA. Balance differential pressure: Less than 20mV. Trigger condition: adjacent differential pressure 0.1V. Balance cut-off: adjacent differential pressure Less than 0.03V. Low voltage protection: Less than 2.8V4. Balance : adjacent batteries as a unit, and multiple columns are synchronized. Balance period: full voltage period (including charging, discharging and idle).5. Sleep power consumption: 200uA low power consumption, the battery can be idle for a long time.6. It can be used to repair model toy batteries and can also be used in parallel with BMS long-term fixed battery pack, Because the chip setting is the greater the voltage difference is, the greater the balance current is, and the long-term fixation will not cause damage to the battery.7. Balance indicator:When the LED is on, it indicates it is in balance.When the LED is off, the balance stops.When the LED light flashes, it indicates the internal resistance of the battery is , open circuit or suspended.8. Installation: suitable for long-term use, installed inside the battery, with low power consumption, low heating, high safety and stability. You can use it with BMS for better balance.9.
