cylindrical 32700 lithium lifepo4 battery cell 3.2V 6000mah for
battery pack solar storage system
About 32700 lithium lifepo4 battery cell.
- Lithium battery is a type of battery that uses lithium metal or
lithium alloy as the positive/negative electrode material and uses
a non-aqueous electrolyte solution.
Lithium batteries can be roughly divided into two categories:
lithium metal batteries and lithium ion batteries. Lithium-ion
batteries do not contain metallic lithium and are rechargeable.
32700 lithium ion battery is with lifepo4 as positive electrode,the
size 32mm*72mm high.32700 can be battery pack,prismatic cell for
many applications,such as solar storage,RV,home energy
system,E-car,bicycle etc.
Deligreen's 32700 supplies good quality and real 6000mah capacity.
Lithium battery is the trend to replace the lead acid battery.
| Battery type | LifePO4 battery | Lead acid battery |
| Nominal voltage | 3.2V | 2V |
| Energy density | 180Wh/kg | 30WH/KG |
| Weight | Light | heavy |
| CBM | Small | big |
| Safty rate | High | low |
| Cycles | 3500 | 500 |
| Memory | NO | YES |
| Environmental protection | Environmental protection and pollution-free | pollution |
More and more people choose Lithium battery to replace the lead
acid battery.Lithium is deeper cycle as to 2000 times,much longer
than lead acid.You don't need to change the battery as frequently
as lead acid battery,which can save your cost in battery.

Quality Testing
| Items | Test Conditions | Specification |
Standard Charge | The "Standard Charge" means charging with constant current 0.2C5 to3.65V, then charging with constant voltage 3.65V to 0.01C 5
under 20±5 , ℃ charging time will not more than 8h.) (Use
Lithium-ion battery charger, which with an accuracy ±0.05V. | |
Nominal Capacity |
The capacity means the discharge capacity of the cell, which is
measured with discharge current 0.2C5A to cut-off voltage at 2.0V at 20±5℃ rest for 30 minutes after the
Standard Charge. |
Nominal Capacity ≥6000mAh |
Cycle Life | After 2000 cycles of charge and discharge, the discharge capacity
is measured with 0.2 C5A discharge current and 2.0V cut-off voltage. |
≥80%Nominal Capacity |
(Storage Characteristic) |
Test the cell initial capacity using 0.2C 5 current at 23±2℃ and
record,then charge the cells with 45% capacity, then storage for 3,
6, 12 months respectively at 20±5℃and relative humidity of 45%~75%,
then the cell is cycled for 5 times with charge with 0.2C5A and discharge with 0.2C5A at 23±2℃, The maximum discharge capacity (longest discharge time) is recorded. | 0.2C5Adischarge time: After 3 months storage ≥4.5hrs; After 6 months storage ≥4.25hrs;
After 12 months storage ≥4.0hrs) |
