·Long life: adopt special lead paste formula, better deep cycle performance;
·Better big current discharge performance: higher specific power, good deep cycle discharge performance.
·Good charge acceptable ability
·better performance in higher or lower temperature: activator is added to the formula, which can be used normally at -20ºC~+50ºC.
·Safety and reliable: good earthquake resistance. Good sealing performance, no acid mist, no explosion in the process of use, the special case can effectively prevent the battery bulge, will not produce heat loss.
·Environmental: maintenance free.

Applications:

·Ideal for EVs, electric road vehicles, and other pure electric vehicles.
·Perfect for field patrol cars, golf carts, sightseeing buses, and other specialized electric vehicles.
·Suitable for electric buses, municipal engineering vehicles, and more.
·Designed for electric trucks, providing reliable power and performance.

Optimum configuration
·The maximum starting current is less than 150A
· The maximum running speed of the electric vehicle is less than 50A
· can be configured with motors below 60V3000W or 72V3500W


Charging Requirements: 
Note: The standard temperature of this charging process is 25ºC, and the battery is charged with the decrease or increase of the ambient temperature. The voltage adjustment factor is + or -4mV (ºC· cell).
Charging process parameters refer to the following:
The first stage: pre-charge, 0.10C3A constant current charge to 2.00V/ cell or charge 0.5h, if it fails to reach 2.00V/cell, the charger should alarm the abnormal situation.
The second stage: (0.15~0.18) C3A constant current charge to 2.40V/ cell or charge time reaches 6h, charge automatically transfer to the third stage;
The third stage: constant current (0.10~0.12) C3A charge to 2.47V/ cell or charge time reaches 2h, charge automatically transfer to the fourth stage;
The fourth stage: constant voltage 2.47V/ cell, current limit 0.05C3A charge, charge until the current is reduced to 0.01C3A or charge when the time reaches 2h, the charge will be automatically transferred to the fifth stage;
The fifth stage: voltage limit 2.67V/ cell, current limit 0.015C3A charge 2h automatically converted to the sixth stage;
The sixth stage: float charge, float charge voltage 2.30V/cell, current limit 0.01C3A, charge 4h.
For example, if the battery model is 6-EVF-100 and the rated voltage is 12V, the voltage requirements for the charging process parameters are as described above six times as much. The rated capacity is 100Ah, where 0.15C3A indicates A current of 15A (A indicates a unit of current, C3 indicates battery capacity).

Battery Performance:
