Description

Traxxas Certified iD-Equipped LiPO batteries provide the punch and power to reach maximum speed. They come in a full range of capacities and configurations. Traxxas iD-Equipped LiPO batteries are engineered to fit Traxxas models perfectly and maximize their potential. Only Traxxas gives you more of what you want: simple installation, a great price, and the most speed and run time available. The patented Traxxas High-Current connector is the standard for efficiency, ease of use, and high-current handling. The balance leads are integrated into the connector eliminating separate balance wires and connectors as well as external balance boards. The Traxxas High-Current Connector allows current to flow freely with virtually zero voltage loss due to resistance. Large, textured surfaces provide good grip and the reverse- polarity protection makes them virtually impossible to plug in backwards. Shrouded wire connections eliminate the need for heat shrink tubing. Beefy, gold-plated copper terminals with large, spring-loaded contact areas ensure a perfect connection every time. Traxxas iD-Equipped Power Cell LiPO packs use a unique construction that results in a firm, rugged, and compact pack that does not require a hard case. This gives them greater capacity and allows the user to monitor the condition of the battery. Unlike a hard-cased pack, if a Power Cell LiPO "puffs" or softens due to damage or abuse, the user can easily see and feel the change in the pack.

  • A1 tank of a battery
Amazing battery, just like Traxxas products usually are. Other comments spoke of puffing or what not, but place this battery on a Traxxas lipo charger, always use balanced charge, and it will last for literally YEARS. Puffing is never a worry in my head. Don't rush $100 and it'll easily give you hours of play, every day, for years. ... show more

  • Runs forever on vxl 3s rustler
My son is running a 2wd rustler 70mph on this battery and gets crazy run time over 30 minutes

  • Be aware, does not fit Rustler or slash without fitting kit
Good Battery, works pretty well. You need special kit to make the battery fit, as it is taller. Roco 4x4 is one of the best sellers on Amazon. Fast delivery to Mexico.

  • Good battery
Battery is expensive but in my TRX4 I can get a couple hours of runtime out of it which is a very positive thing

  • Absolutely essential upgrade
Must have upgrade if going brushless. I have run this battery for about 45 minutes at a time and saw no sign of slowing down. I prefer not to drain these types of batteries down too low to where they set off the low voltage protection both to protect the RC, the battery and myself. However, I highly recommend this battery and you definitely can’t beat the quality products that’s Traxxas puts out, so the slightly higher price was more than worth it for piece of mind on these types of batteries. ... show more

  • What did I do wrong?
First charge performance was awesome! After charging a second time, the battery was used for only a few minutes and then left to sit. After about two weeks I went to use the battery and realized it would not work or take a charge. I returned the product but was given no replacement or refund. Really disappointed. Has anyone else experienced this? ... show more
