and carrying. Here are necessary foams among modules and BMS for isolation and vibration resistance.
After-sale Service
For the warranty and after-service we will follow the following principle.
Warranty year(s) for this model of battery pack is specified by supplier. In the period of warranty, there is any
problem as the following description, we will take responsible for the replacement and repair.
1> The whole battery pack can not be charged or discharged.
2> Under the standard condition for testing, capacity is not same as nominal Ah. It is less than 80% in the first
year, or 70% in last warranty year (if the last warranty year is provided as warranty period).
3> There is liquid leakage.
4> There is some damage on battery pack’s case and accessory because it is caused by the battery.

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℃.
