Venom 4S 9000mAh LiPo battery


I decided to get a Traxxas X Maxx R/C truck but didn't want to go with the Traxxas batteries and charger because I wanted flexibility in what brand of battery I bought when it was time to replace them. These batteries came highly recommended by RC Planet as a good alternative to Traxxas batteries so I decided to go ahead and get two. They arrived quickly on the same day the truck did. However, one of the batteries had a dead cell. I immediately called Venom customer service and talked to someone there. He apologized for the inconvenience and said he'd get another one shipped out that same day. When the replacement arrived a few days later, there was a Post-It note stuck to the box with a hand-written note, again apologizing for the inconvenience and let me know that he had personally checked this battery before shipping to make sure it was good, which it was. I've charged the batteries with my Venom Pro Duo 80W charger and have run them in the X Maxx. They worked great! I got at least 25 minutes of fairly hard running and they were discharged to 3.81V per cell, perfect for storage. I could have easily gotten another 10 or 15 minutes out of them without discharging them too low and damaging them. Great battery and great company. And great customer service!
