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)

All of CTS battery cells in a pack are with very high consistency.In a pack, each cell has its ownsole electronic code(ID number) for quality control after-sale. Assume one cell in a pack is damaged in any reason after several years later, we could provide a exactly same cell to the client to replace this damaged one(same voltage, capacity, impedance,etc.), in order to make sure all of the cells in this pack with very high consistency. CTS has a strong system working for this.
Battery assembly process
About CTS
Do the batteries have a warranty?
§ Yes, currently 3 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
Customer Feedback
We are happy with your battery quality. I've also been very happy with your good support,
let's continue discussions and work on more,tks.----Michael (from Berlin,Germany)
I wanted to thank you for your help. The battery pack tested at over 100AH with over 5400Watt hours! It ran two home refrigerators (one is in my hot garage with no A/C) and my 65" TV for about 20 hours! --- Tom (From L.A USA)
I am thrilled to have a superior pack from your company! --- David (From Melbourne Australia)
