Application of high-speed toll ETC products

Previously, the high-speed charging ETC product used a 3.2V lithium iron phosphate 14500 battery, which was charged using a solar panel photosensitive screen, resulting in high costs

Now ETC products directly use Huahui 3.2V HFC1450-500mAh positive/negative same terminal lead out to replace traditional steel shell batteries, and are equipped with a solar dedicated charging management IC, making the entire product performance better, safer, and more cost-effective!

Huahui Battery has successfully used over 15 million units in ETC products!
