The Technology info with regard to lithium li-ion battery 12v 70ah lithium battery
MERITSUN Lithium Battery BMS / PCB / PCM.
Li-ion cells should always be used with a protection circuit to prevent the cell from over charging or over dis-charging. Choosing the correct circuit and applying it appropriately is vital to the longevity your batteries and your own safety. MERITSUN test each Cells and BMS/PCB/PCM before manufacturing and promise it is functional and safe.
BMS / PCB / PCM is the "heart" of Lithium battery pack. BMS (Battery Management System) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.

The Instruction / Note with regard to lithium li-ion battery 12v 70ah lithium battery
Battery Operation Instructions: | ||||||
1. Charge:Connecting the battery pack to the charge controller, connect the charger to recharge. | ||||||
2. Discharge:Connecting the battery pack to the load, connect the load to discharge. | ||||||
3. When you combine the battery with series or parallels, if there are oxidation layer on the surface, you Should brush surface to the metal glow with thin steel brush to lower the connective resistance to the minimal resistance. | ||||||
4. When combining with many batteries, if the voltage between the two electrodes is over 36V, the safe Voltage for human beings, to guarantee the safety, you should not touch the two electrodes with your body. | ||||||
Notes: | ||||||
1. Need for regular recharging (even if not use), must charge and discharge for three months one time. | ||||||
2. Do not expose the battery to extreme heat or flame. | ||||||
3. Do not short circuit, over-charge or over-discharge the battery pack. | ||||||
4. Do not disassemble or modify the battery pack. | ||||||
5. Do not handle or store with metallic like necklaces, coins or hairpins, etc. | ||||||
6. Do not reverse the polarity of the battery pack for any reason. | ||||||
7. Do not immerse the battery pack in water or sea water, or get it wet. | ||||||
8. Use a constant current, constant voltage (CC/CV) lithium-ion (Li+) battery charge controller. | ||||||
