(with Our Match Cell by Special QC&QA for SOC , SOD , internal Resistance for all cell in the group to have a pack's consistency for best performance and long life !)

Type: HP-20AH , quantity > more than 100 cell

Power Type / 3.2V 20AH

The PW (power type) series batteries, featured as high

continuous & peak power, battery of this type focus on

best power supply ability.

Hipower began LiFePO4 battery production in 2004. Batteries Appearance are widely used in electric vehicles, energy storage, marine,

industry, telecommunications, electric tools, etc. For LiFePO4 Overall dimensions: 103 x 41 x 168 mm

molecular structure is reliable and has a high degree of electrical L*W*H (mm, inches) 4.06'' x 1.61'' x 6.61'' inch

conductance. Hipower LiFePO4 batteries offer high continuous Weight: (Kg / lbs) 0.83 kg / 1.83 lbs

/ peak power even when nearing the end of the depth of Terminals on poles : M12 Nuts

discharge, batteries also will accept large charging current Poles Distance: (mm) 54 mm

such as regeneration when the EV’s are braking or reducing

speed. Those features give electric vehicles above average

performance when starting or accelerating or climbing.

Common advantages

1. Long cycle life. No memory effect.

2. High C-Rate discharge / charge capability.

3. High peak power available under high DOD.

4. High energy density, small size, light weight.

5. Good performance at high & low temperatures.

6. Environmentally friendly.

7. Intrinsically safe.

Remarks:

1. C-rate can be used to discribe current, "C" means

capacity rating (Amp-hour), easy for calculating. For

example, 50AH cell, 3C means 3*50= 150A, C/5 means

1/5*50=10A, also can be called 0.2C.

2. Test is accord with QC/T743-2006.
