GOT 6 HRB 6S 4500 100C LIPOS THEY ALL COME WITH 9-11 MILLIHOMS PER CELL AND START TO RUN WARM AT 1/4 DISCHARGE ON 30 AMP CYCLE MAGINE WHAT THEY WILL DO AT 80 AMP OR HIGHER! BY THE TIME THE 30 AMP CYCLE DONE THERE HOT! I TOLD HRB ON AMAZON , don't ANSWER. TELL THEM ON ALI EXPRESS, THEY WANT PICS, CANT SHOW HEAT THOUGH... FOR 100C THEY SHOULD RUN ALOT COOLER THAN THAT! LIPERIOR USES Anode and Cathode thin film coating technology, which lowers the internal temperature of the battery cells and improves battery performance, life cycle, and safety! THATS WHAT HRB NEEDS TO DO!
