melasta 8.4V 4200mAh 7 Cell NIMH Battery Hump Battery Pack compatible with Tamiya Connector for RC Vehicle RC Car RC Truck

Fits in a Traxxas Rustler (with old TRX connector). Gives a good long run time. Goes fast and easily wheelies.I had a bit of reservation after buying a different NiMH battery on Amazon that turned out to be not too good. However, this one seems fine and delivers plenty of power for a 2WD car. I did think of going with LiPos but NiMH is safer.

I bought this as it seemed like a decent cheaper alternative to an official Traxxas battery, the seller confirmed that this would charge from an official Traxxas ID charger. Unfortunately it doesn't charge, I'm unsure if it's a fault with the battery or that it isn't compatible with the Traxxas charger. I contacted the seller via Amazon to ask for some advice, I never got a response so I returned the battery, looks like I'll be sticking with the official Traxxas batteries from now on.
