RoaringTop lithium polymer batteries are manufactured to meet the highest requirement of the competition-level customers. Our cells are made of patented constituents of electrolytes, which have excellent performance at low temperature (with high discharge current even under -10?) and higher discharge rates compared with other general batteries with similar density. By adding special nano-tech materials and using automatic/semi-auto equipments during cell processing, we obtain battery packs with high energy density (up to 230Wh/kg), low internal resistance, long cycle life, and high quality consistency. Meanwhile, a proper amount of Li3V2(PO4)3 added to the anode of our battery packs can effectively decrease the voltage dropping speed at the early stage of the battery discharge procedure, featuring flat discharge curve during normal usage. Our products are shipped from Culver City, California.
