LRP "Big Mama" 2S Competition Li-Poly 55C Hard Case Battery Pack (7.4V/7500mAh)
I purchased (3) of the 7200 50/100c LRP lipos about 5 weeks ago. After 5 weeks of saturday racing (17.5 TC large outdoor track) ALL 3 have swelled equally!! They are puffing to the point where I don't want to use then anymore. I always charge at 1c and balance during every charge. Every qualifier I would rotate the packs and keep them half charged during the week for storage. I had heard bad stories about LRP packs but I figured they were "unlucky" or exaggerated. Buyer beware! Maybe the 7500 55c are better but I would be VERY careful when considering buying these cells
