With a capacity of 5200mAh, you’re assured of extended fun times in the mud or wherever your Stampede adventures may lead. The 50C discharge rate aligns perfectly with the truck’s need for speed, ensuring you exploit the 30+ mph performance that the Stampede is known for.
I’ve run several cycles on a battery analyzer, and the results have been impressive. The total internal resistance is at 10 milliohms, which means that the energy loss during power delivery is minimal. This assures you of efficient performance throughout your driving session.
Even in situations where the replacement battery cells’ balance was initially off (0.1v difference), I found that they were easy to balance, pointing to a well-constructed battery. And with a Dean-Style T connector, the connection is secure, further enhancing the battery’s performance.

Firstly, the 5200mAh capacity makes for prolonged, exhilarating run times, which means more back-to-back wheelies, daredevil jumps, and dirt-roosting acceleration. It’s the kind of performance that puts a big smile on any RC enthusiast’s face, as I’ve experienced with my own son.
The 50C discharge rate aligns perfectly with the Stampede’s torquey drive-train, providing enough punch to propel the truck across a variety of terrains at its top speed of over 30 mph. Whether it’s a mad dash through the grass, an all-weather adventure, or a thrill-filled snow shred, this battery delivers the required energy without breaking a sweat.
In terms of charging, the Zeee 2S is just as impressive. Quick charge times mean less downtime and more action, while the low heat generation and internal resistance ensure that the battery maintains a high performance throughout its lifespan. This is particularly important for a powerhouse like the Stampede, which relies on consistent power delivery for its extreme maneuvers.
Considering its quality and performance, the Zeee replacement battery comes across as an excellent value option, particularly for those on a budget. And with a size and weight that fit snugly in the Stampede, it’s like this battery and the truck were made for each other.
