Home run!

Bought three to go with my new single battery mod. Couldn’t be happier. One lasts all day at 60w. Didn’t even need three. Great battery. Highly recommend.

Battery is perfect for my use in single battery mods (AEGIS MAX/GRUS100). There's absolutely nothing any battery review will say anywhere that matters more than what Mooch has to say about them. He IS the resource for battery reviews/research and there is a reason even DJLSB references him when bringing up battery tech. He rates this above average last i checked which, from him, means the world.
