With the development of new energy vehicles, lead-acid start battery is being replaced by Lithium Iron Phosphate batteries which have the advantage of  high charge / discharge performance, lighter weight, smaller size, longer cycle life, no pollution etc.

After two years’ research and tesing on start batteries, we build up a professional team which successfully designed a series of car start battery (12v20Ah, 12v40Ah, 12v60Ah, 12v80Ah)with BMS built in .

Follows are the details. More information, you can check at www.kokpower.com, here, you can download the catolog.

How These Car Start Batteries Being Made？

1.All of our cells are high powerful original brand new A123 20Ah; as you may know that A123 system cells are the best LiFePO4 cells in the world by far.

Our automotive batteries offer phenomenal starting power and massive deep cycle reserve power. They are capable of providing engine cranking pulses of 1300 amps !

2.Battery built with high quality BMS: the BMS is specifically designed for car start batteries,after 2 years of R&D and testing.

It has 4-fold of over current protection:

(1)continuous discharge current of 100A ;

(2)125A protection for 30s;

(3) 400A for 3-5 s protection;

(4) pulse current1300A

And the MOSFET and IC, the most important parts of BMS are quality brand.

While Lithium Iron Phosphate has helped reduce the weight of automotive batteries, Compared with the lead-acid batteries,the LiFePO4 motorcycle start batteries are:

Smaller: 1/2  of the size

Lighter: 1/3 of the weight

Safer: Can be installed in any direction without leakage

Longer Life: 7-10 times longer

Our Lithium Iron Phosphate technology with BMS offers enhanced safety compared to traditional lithium iron battery types as well as Lead (Pb) batteries

At the same time, we have  developed car start battery  with monitor on iSO/ Andriod, showing battery status (voltage/ SOC/ charging status/ starting status, etc)within the bluetooth range.you can monitor the status of the battery at any time, when your battery is abnormal, will immediately send information to your phone, If you are interested in the batteries, please contact us soon,more information will be sent .
