NASTIMA 8.4V 4000mAh 7-Cell NIMH Hump Battery Pack Compatible with Tra Connector for RC Cars, RC Truck and RC Boat

Customer service could not be more helpful. If you have the correct connector, not "id" type, this is a great battery. Just know that you cannot simply buy and put your Traxxas id style connector on it and expect it to fully charge. I was told by customer service that this battery takes about 5 to 6 hours to fully charge. My Traxxas charger was stopping at around 4 hours probably because of the "id" connector I spliced on to it thinking it's a 3000mah battery. This cannot be used with a Traxxas that uses the "id" type connector. Make sure you have the older style Traxxas connector. Will not charge properly with a Traxxas "id" charger.

Great battery plenty of power. Lasts along time.

Better battery than what came with the truck. Got this as second battery and use it as the main.

These batteries are great, last a long time. Well worth the money excellent service especially Emma

Adapter need.

Battery worked fine, it runs good, plenty of play time between charges

Charge lasted less than a minute

Works great

Parfait

La usé para un arrma senton mega y a diferencia de la que viene incluida con el rc no dura lo mismo, además hace que el variador se caliente más rápido. Consideren otra marca para sus rc. Por lo menos en arrma no funciona muy bien.

Well made product holds charge well

Very good

Ordered 2 of these for my redcat gen 7 crawler, great batteries, got approx 2 hours run time out of each one!! Will be buying more.
