—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

Why there are lifepo4 cells with insufficient capacity.

Used battery

When lithium ions are removed from the cathode, in order to maintain the electrical neutrality of the material, metal elements will inevitably
be oxidized to a high oxidation state.
The used battery with oxidized lithium ion,the capacity doesn't reach the rated.

Bad quality

Some batteries with flaws and quality problems,please buy your batteries from a realiable supplier.

Low SOC for a long time

The lifepo4 battery is shipped with 50%-70% SOC,3.2V or higher.after months of stock or transportation with lower SOC,the capacity probably gets low.
A lithium battery requires charge one time per month at least.When you receive lower voltage cells,charging it to 3.65V and discharging to 2.5V for cycles.


The properties of electrolyte significantly affect the specific capacity, service life, rate charge and discharge performance, working temperature range
and safety performance of lithium batteries.
Refurnished battery is refilled with electrolyte that effects the life and capacity of battery.

Internal resistance

High Internal resistance effects the capacity too.

Deligreen tests the capacity of battery before shipping,try best to make the battery with sufficient capacity.
