2. Low internal resistance
Methods of reducing the internal resistance:
**Using carbon coated aluminum foil
**Multiple electrode tab design
**Increasing the width of electrode tab
**Coating PVDF on battery separator
**Pore-creating artificially

3.Long lifespan

Usable for more than 2,000 charge-discharge cycles

> 4 times than lead acid battery
> 2 times than li ion battery

4.Excellent performance in high and low temprature 
Usable in extremely cold and hot environments (-20 to 60 ºC)

3. Some Related Application Case

Each battery module in parallel is fixed with steel parts,then put them together by pull rob.After this,there are covers to protect battery with case and BMS.

5. Our battery cells catalog

Melsen uses Lithium Iron Phosphate (LiFeP) batteries for electric vehicle conversions. The battery cells utilize the latest advancements in nanotechnology.

All of our battery packs(12v-400v,12ah-200ah) are made of those following lithium ion pouch cells.
These cells are very safe in normal operation, DO NOT cause fires as the early Lithium Phospate batteries.

The selected batteries solve the Safety concerns of being in an Electric Vehicle (EV) / Electric Car Conversion Kit, every cell has a built-in safety device if punctured or damaged, will vent to the atmosphere making the cell much safer.

Compared to lead acid battery, it is 4 time lighter in weight , and 4 time longer in lifespan.
Compared to li ion battery, it is 2 time lighter in weight , and 2 time longer in lifespan.
Compared to lithium ion square battery, it is 0.5 time lighter in weight , but much safer when using.

9. FQA

Do the batteries have a warranty?

§ Yes, currently 2 years; extended warranties are also available.

How long do the batteries last?

§ 10 years / 200,000 KM (124,275 miles) [calculated based on 100km battery pack]

§ 2000 charges & discharges at 100%.

§ This means approximately 10 years of normal use 200,000 KM. (124,275 miles)
§ Normal use is defined as 20,000km/year. (12,500 miles/year)


Do you use Lead Acid Batteries?

NO WE DO NOT! Our reasons:
§ Lead Acid Batteries do not allow as many charge & discharge cycles as advanced lithium batteries
§ Lead Acid batteries degrade after 300 charge cycles in an electric car until they expire, approximately 1.5 -2 years of driving
§ Not cost effective to change your battery pack every two years
§ Lead Acid is HEAVY, and reduces your range, doesn't supply continuous power


Welcome you to visit our production base and to check our production lines!
