·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.
Best Configuration
·The maximum starting current is less than 225A.
·The current is less than 75A when EV is at maximum running speed
·Electric motor can below 48V3500W or 72V5000W.

Charging Requirements: 
Table1 charge phase conversion setup

Phase	Current	Voltage	Time h	Conversion condition
T1	Constant current I1=0.15C3	Charge to U1=2.4V/block	6	charge when voltage is U1 or charge time is 6h.
T2	Constant current I2=0.1C3	charge to U2=2.45V/block	1	charge when voltage is U2 or charge time is 1h.
T3	Constant current I3=0.05C3	charge to U3=2.45V/block	2	charge when voltage is U3 or charge time is 2h.
T4	Current limiting I4=0.05C3	Constant voltage 2.45V/block	3	charge time is 3h.
T5	Current limiting I5=0.015C3	Constant voltage 2.67V/block	1.5	charge time is 1.5h.
T6	Current limiting I6=0.01C3	Constant voltage 2.4V/block	2	charge time is 2h.
Note: 1)Battery is monoblock structure, cell specified voltage can use table value multiplied by block quantity. Cells in series can become battery group, then use cell specified voltage multiplied by cell numbers. 2) The charging voltage should be adjust appropriately with the change of ambient temperature. When the baseline temperature (25ºC) is 1ºC, the battery charging voltage should be reduced by about 3mV/single cell, and vice versa.

For example, the battery model is 4-EVF-150, the rated capacity is 150Ah, 0.15C3A indicates the current is 22.5A(A indicates the current unit, C3 indicates the rated capacity of the battery), and the rated voltage is 8V. The voltage requirement of the charging process parameters is four times of the above requirements.
