Yaheng started the EV battery business from 2003. More than twenty years experience in the VRLA battery for electric vehicles. Yaheng innovated a lot to make the Electric Vehicle batteries. 12V12AH EV Battery is Cadmium free design at 2 hour rate, popular for electric scooters and wheelchairs, the size is L 151*W 98* H 95 total height 101 mm, 4.2 KGS. F2 terminals, Nuts and bolts terminals available.
A lot of tests done before we brought 12V12AH EV battery to market. Some tests took about one year to finish. The EV battery must last more than 350 cycles before the capacity get to 70% of the nominated capacity. Some chemical formulations can make the EV battery last more than 400 cycle at 100% DOD. From different chemical formulations, Yaheng can choose the right one for target market, for example in low temperature environment and high temperature environment, the composition of plates is different.
With complete production chain, Yaheng has the prompt response system to develop batteries upon the request from customers. The cooperation with Addenda to develop chemistry for plates, Yaheng Machinery factory can develop the right equipment for manufacturing process, the lead powder machine can make the particle size according to the application to make full use of the active materials inside the battery.
The production capacity of the 12V12AH EV battery can be 30,000 PCS a day. The automatic production lines make the output high efficiently. Automatic stacking, Welding, sealing, injection of electrolyte, printing can save a lot of labor cost. Good consistency in capacity, OCV, inner resistance is key point get good performance. Yaheng assort the batteries according to voltage, capacity, inner resistance in the activating and charging process. The assorted battery bank for EV is very important for good performance. The regular delivery time is 10-15 days. The lead time for customized battery case will be ten days more.
With 6S manufacturing process and good quality, Yaheng can save a lot of after sales service. Although Yaheng provides one year after sales service, our customer seldom complain the quality. This is also trouble free method for our customers. Yaheng’s principle is to make the cooperation high efficient and benefit both sides.
