Powerhobby 2000mah 2s 50C Lipo with EC2

Brand: Powerhobby
Voltage: 7.4V
Capacity: 2000mAh
Discharge Rate: 50C (Continuous) / 100C (Burst)
Connector: EC2 Plug
Size: 81 x 31 x 15mm
Weight: 102g

Highlight: Long Running Time | High C-rate

This 2s lipo battery with EC2 connector is the best solution for upgrading batteries in the Typhon Grom and Granite Grom. It has an increased capacity of 600mAh compared to stock batteries, which means almost half of the runtime can be extended.

In addition, in the actual run test, this battery’s power output is large and stable because the C-rate is 20C higher than the stock battery, which means that it increases the maximum discharge power by 60%, which improves the acceleration and responsiveness of these small scale RC off road, and you can clearly feel the difference in throttle control.

The 50C allows the motor to receive a stable input voltage throughout its operation, keeping it running efficiently even under frequent and fast throttle control. Therefore, if you want to improve the bashing performance of your Typhon Grom or Granite Grom, then this battery is the best choice.

Common Questions

Q1: Can they run 3s lipo batteries with the stock brushed system?

Yes, provided the throttle setting is set to 75% or 50% to prevent the motor from overheating due to too many watts. What you need to know is that limiting the throttle will result in the 3s lipo not producing as much watt as a 2s lipo running at 100% throttle.

Q2: What distinguishes an EC2 from an IC2 connector?

In short, the IC2 and EC2 are compatible and the IC2 is a smart version of the EC2, however, due to its low price, the EC2 is an ideal replacement for the IC2.

Q3: Are Spektrum chargers compatible with other brands of batteries?

No, it is not.
