2. Main Features of Our EV Battery Cells
1. High energy density
| | lifepo4 battery cell | LiNiCoMn battery cell (ab.NCM battery) |
| weight energy density | 150wh/kg | 200wh/kg |
| volume energy density | 280wh/L | 334wh/L |
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)
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.
We support OEM
(12-400V,20AH-160AH)
4. More other battery packs4.1. our 3.6v modules , designed for big electric vehicles like 10kwh / 20kwh / 30kwh.
4.2. our 12v battery pack , designed for car start or small energy storage or solar. We also could make 12v with other capacity from 12ah to 200ah, please contact me for details.
4.3. our 24v battery pack , designed for small energy storage or solar. Other capacity is also available from 12ah to 200ah.
4.4. our 48v and 72v battery pack , designed for small electric vehicles like motorcycle or golf cart . Other capacity is also available from 12ah to 200ah.
5. Our battery cells catalogMelsen 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. | | | | | |

8. Order Information
Sample is avaliable and welcome.
Trade term: FOB Shenzhen or Guangzhou; EXW, CIF,DDU and DDP are available.
Delivery time: 7 working days for sample order, 15- 25 working days for mass order.9. FQADo 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!
