graphene battery for e rickshaw 72v 40ah electric bicycle battery
CTS is a professional manufacturer engaging in research,development,production,marketing and service of lithium ion pouch battery cell, battery pack and battery management system.
LiFePo4 and NMC(Li(NiCoMn)O2) are the major material. We have more 30 types of cells, and could make OEM battery pack from 12v-200v, 10-200ah, which can be used in electric vehicle, E-bike, UPS, energy storage system, telecommunication base station, E-scooter, E-tools,unmanned airplane, golf cart, fork lift, cleaning car , electric wheelchair, etc.
Description of lithium ion battery 72V
We accept OEM for other voltage like 48V 60V for motorcycle amd scooter
Specification of lithium ion battery 72v
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.

What is the different between our scooter battery and others?
Do the batteries have a warranty?
§ Yes, currently 2 years; extended warranties are also available.
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
