other protection functions. With automatic charge and discharge management and single cell
balance function.
Supports maximum 200A discharge current(Refer to Chapter 8 for detailed parameters).
Supports up to 8 units in parallel, so that the total capacity can reach 12V 800Ah
With external charging activation function. In the shutdown state, when the external charging
voltage is >14V,the battery can actively wake up, and allow charging and prohibit discharging;
It can be equipped with MEH-B display panel for battery switch and battery status (voltage,
current, SOC) display.
The battery has low self-discharge rate. The standby power consumption after the battery is
turned on is <50mA, and it can be reduced to <0.1mA after the battery is turned off.
Wide working temperature range, -30℃~ +60℃. Good cycle life and discharge performance
