protect the battery over charge and discharge, over current and
over temperature, internal cell balancing.
Batteries can be customized according to customer requirements,
such as voltage, capacity.
Maintenance-free and no acid or water for maintenance in usage
Wide operating temperature: High temperature resistance(-20~60
degrees Celsius).
Steady performance: High power output, low self-discharge rate,
less than 3% monthly.
Using the technology of lithium iron phosphate cell, superior
safety,thousands of cycles, 100%DOD, under normal conditions.
Built-in automatic protection for over-charge, over discharge, over
current and over temperature.
Lithium battery is the trend to replace the lead acid battery.

Lithium battery pack is with more than 2000 cycles life,lead acid
battery is only with around 500 cycles,you need to buy 3-4 lead
acid battery that as long life as lithium battery.
Lead acid battry is much bigger and heavier than lithium
battery,lithium battery pack is used in more applications.
Lithium battery pack,why Deligreen?
Lithium battery pack is a system of lithium batteries,containg
lithium battery,BMS,outer box.Battery pack is widely used in many
applications,such as RV,caravan,solar system,camping,energy storage
system,Led street lamp,golf cart,marine,boat,e-car,motorcycle etc.
Battery pack needs to be customized,before placing the order,we
need some important parameter.ex.
- Battery pack application
- Battery cell:LFP or NCM,it determins the price,size,spec etc
- Nominal current and voltage
- Max continous dischaege
- Battery pack size
- Outer box material:plastic,Irion,epoxy board
This is the requirement/customized sheet for you to fill in to get
a most precise price.

FAQ
Q: What is the life expectancy of a Lithium battery?
A: The typical estimated life of the Lithium Iron Phosphate
(LiFePO4) battery is 5-15 years or 2000 to 8000 charge cycles. One
charge cycle is a period of use from fully charged, to fully
discharged, and fully recharged again.
