Used, about 100 cycles, but in very good shape 6S 2600 Mah Li-on battery packs. The Molicel batteries are spec'd at 500 cycles according to their spec sheet. So these have a long way to go. They have been well taken care of and always balanced charged. They weigh about 310 grams each. I soldered them together using 60 amp rated tin plated copper tabbing strips. The output wires are high quality Castle Creations 13AWG. NOT the typical 14AWG wire.
