Product Details

The electrical parameters of the XD 48v 200ah lithium ion battery are compatible in all respects with those of an AGM lead battery of 12V. In the vast majority of cases, the charging system can be kept the same and no additional accessories are required to perform the replacement.

The products XD are light, compact, efficient and can be used for all types of uses and applications. XD are designed to drop-in replacement of old generation batteries (Lead VRLA, AGM or OPZ batteries) in 12V, that are low performance and harmful to the environment (use of heavy metals and acid electrolytes).

8. Battery operation instruction

Charge and discharge

1. Charging current:Do not surpass the largest charging current that specification stipulated.

2 .Charging voltage:Do not surpass the highest limited voltage that specification stipulated.

3 .Charging temperature:within temperature scope that specification stipulated.

4. Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous

5. Special note: Short time doesn't affect the use of the battery overcharge too, but for a long period of time over discharge or over charge can affect the function of the battery failure, or the battery can't use permanent, appear serious safety hazards, need long time floating please use the recommended floating model specification. Battery when not in use for a long time, because of its own self-discharge characteristics can also cause discharge, to prevent the occurrence of a discharge, battery should maintain a certain capacity, maintain the voltage at 50% state of SOC.

9. Other Chemical Reaction

Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the discharge time is much shorter than the normal after full charged, even battery is charged correctly, and this may indicate it is time to change the battery.
