Advantages of Lithiun ion Battery than Lead Acid
Lithium-ion batteries are the best option. With Lithium, with little to no maintenance is makes it the easiest option that is also one of the most environmentally friendly batteries available.
Lighter and Smaller
Lithium-ion batteries are smaller and lighter Lead-Acid batteries, around a third of the weight and half the size they are better for those who are limited in space.
Slim and Sleek Design
They are much better looking than the Lead-Acid batteries which are bulkier and heavy. Lithium-ion batteries look futuristic.
Higher Efficiency
Lithium batteries has a Depth Of Charge of 80% unlike Lead-Acid which has 50%, they can discharge completely without losing amps.
Increased Cycles
Lithium batteries can average around 4500 cycles making it a great long term solar storage option and e motorycle renting.
Consistent Discharge Voltage
Lithium-ion batteries stay consistent during the discharging process making it a better and safest option, and it also protects the electrical components.
Better Long Term
The lifespan and ability outperform the Lead-Acid option although the initial cost is higher, the return on investment is better.
Key Features
- Longer cycle life: 20 times longer cycle life and 5 times longer float life compared to lead-acid batteries.
- Lighter weight: about 40% of the same kind of lead-acid battery weight.
- Higher power: offer two times of the lead-acid battery power, and even high discharge rate, while maintaining high energy capacity
Safety Assurance
Passed abuse and safety test such as drooping, nail penetration, short circuit, thermal shock, impact, crush, over charge, over discharge. and there is no fire and no explosion with stable chemical structure.
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
Applications
a. UPS backup
b. Mobility Devices
c. Solar energy Storage
d. Caravan and camping
e. Personal power packs
f. Medical Equipment

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.
After-sale Service
For the warranty and after-service we will follow the following principle.
We offer two year warranty for LiFePO4 type battery pack. For the charger and BMS here are one year warranty. In the period of warranty, there is any problem as the following description, we will take responsible for the replacement and repair.
- The whole battery pack can not be charged or discharged.
- Under the standard condition for testing, capacity is not same as nominal Ah . It is less than 80% in the first year, or less than 70% in the second year.
- There is liquid leakage.
- There is some damage on battery pack’s case and accessory because it is caused by the battery.
- The charger is not working properly.
