Safety Test
No fire, no explosion
Charing to 3.7v and do nail penetration test, there is no fire, no
explosion, no any other obvious changes.
Nail Penetration Test and Overcharge Test
After testing, no fire and no explosion, that is definitely
approved than our lithium batteries deserve you.
Battery care and maintenance
The cycle life of li-ion battery would be shorted if the battery
alway be kept as fully charged state. For
long time storage, keep the battery as 40~60% state of charge (SOC)
and discharge and charge every one or two
monthes.
• Battery should be kept under dry and ventilation condition. Do
not put the battery close to fire and explosive
LiFePO4 is best-choice of materials in commercial Lithium batteries
for large capacity, high power and safe strict applications, such
as Home solar energy storage, power tools, wheel chairs, e-bikes, e-cars and e-buses, solar
storage system etc.
Advantages of 14.8V 20Ah
- Punctual lead time, Perfect LOGO Printing on the product
- Good performance at -40 ~ 60℃ (Low temperature performance: After being kept at -40 ° C for 4
hours, it is discharged at a constant current of 0.2 C to 2.5 V,
and the effective discharge capacity is not less than 70% of the
normal temperature saturation capacity)
- High energy density
- Excellent safety
- Dual IC chips, that can anti-shortcircuit, anti-overcharge,
anti-overcurrent, anti-overload
- Environmental-friendly: No Pb, Cd added
- Test one by one before shipment
Storage Conditions
◆For long time storage ,the battery should be charged to Approx 60%
SOC ,its corresponding voltage should be 1.05times of nominal
voltage(24V,36V,60Vor72V),usually it's voltage in shipment .The
battery should be kept in storage in dry and ventilated place.
◆ The battery pack and charger should be stored in clean, dry and
ventilated place, avoid contacting with corrosive materials and be
away from fire and heat.

Advantages of battery:
Advantages of battery:Longer Cycle Life: Offers up to 20 times longer cycle life and five times longer
float/calendar life than lead acid battery, helping to minimize
replacement cost and reduce total cost of ownership.
Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop
in' replacement for lead acid batteries.
Higher Power: Delivers twice power of lead acid battery, even high discharge
rate, while maintaining high energy capacity.
Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion
or combustion due to high impact, overcharging or short circuit
situation.
Increased Flexibility: Modular design enables deployment of up to four batteries in
series and up to ten batteries in parallel.
Wider Temperature Range: -20℃~60℃.
