The main characteristics of lead-acid batteries
Safety seal: In normal operation, the electrolyte will not leak out of the battery terminal or shell. There is no free acid. A special absorbent separator keeps the acid inside. There is no free acid inside the battery, so the battery can be placed anywhere.
Venting system: When the internal pressure of the battery exceeds the normal level, the VRLA battery will release excess gas and automatically reseal to ensure that there is no excess gas in the battery.
Simple maintenance: Because the gas compound system converts the generated gas into water, there is no need to add water during the use of the VRLA battery.
Long service life: The VRLA battery with lead-calcium alloy fence with anti-corrosion structure can be used for 10-15 years with floating charge.
Stable quality and high reliability: Adopting advanced production technology and strict quality control system, VRLA battery has stable quality and reliable performance. Voltage, capacity and sealing are 100% inspected on the line.
What are the reasons why the lithium iron phosphate battery protection board has no charge and discharge protection?
1. It may be over-charge, over-discharge, over-current, short-circuit, and over-temperature;
2. Use a multimeter to check whether the charging and discharging MOS tube is turned on;
3. If the lithium battery protection board is equipped with LED, it will alarm if the LED flashes for 0.5 seconds if it cannot be charged or discharged;
4. If the lithium battery protection board is with a host computer, you can connect to the host computer to view the protection status;
5. The lithium battery pack protection board has a weak point switch, please check whether the weak point switch is turned on.
