I am upset with MaxAmps it took two weeks for me to get my order. Then they forgot to include the Traxxas connection that was supposed to be a part of my order. My friend also put in an order at the same time and they connected the connection reversed on his battery, and when he plugged it into his can it blew a cell in his battery. And what did they do for all this trouble I got a free shirt. Now it will be over three weeks from the time I ordered my battery until I can drive my car.
