Product Description

3.7V 30Ah Westart High Charge Rate Ncm Lithium Ion Polymer Battery 

30% lighter and 30% more energy dense than LiFePO4 
Fast charge and discharge, Deep Cycle. 100% recyclable and non-toxic.

• Voltage: 3.7V nominal, 4.2V max, 3.0V min
• Long Cycle life >2000 cycles.
• high discharge rate 4C continuous / 8C peak(10S @SOC 40~60% @20ºC~+45ºC)
• Consistently low internal resistance. (=longer life)
• Safe NCM chemistry, proven performance in EVs.
• Higher energy density 257wh/kg power and the energy density of pack system has reached to 160KW/kg This means more Ah in a smaller lighter package.

An appropriate charger and battery management system is required for cell balancing and protection from overcharge and over-discharge.
Different Sizes Based on our 30Ah cell for general purpose, we can assemble 3, 4, 5 or 7 pouch in a stainless steel or aluminum casing to make 90Ah to 210Ah NCM modules.

NCM Lithium battery module technical Advantage

- With our unique module design we make it easy to build small and large batteries out of NCM pouch cells.
- The plastic holders ensure a good insulation and a rugged fixation even for challenging applications.

NCM Lithium battery module feature

- Module design with terminal bolt to make easy assembly
- Double sealed design, to protect battery punctured by external forces with high strength
- Explosion proof valve module housing design make relief protection
