Arrma Senton 4×4 Battery Upgrade

Arrma Senton 4x4 Battery Upgrade

Upgrading your Arrma Senton 4×4 is fun, especially if you want to have an RC vehicle with a difference. There are many ways to improve your vehicle’s performance, and replacing a more powerful battery is the easiest option. Below I will recommend two high-quality lipo batteries that are reasonably priced and are perfect for the Senton 4×4.

Upgrade method 1: 2s lipo

When you buy the brand new Arrma Senton 4×4, it comes with a 3300 mAh 8.4V 7-cell NiMH battery and it maxes out at 19 mph. If you want faster speed and longer runtime, you can replace the NiMH batteries with lipo batteries. The Senton 4×4’s powertrain is compatible with 2s lipo batteries, so you can run them straight out of the box.

This pack of batteries is suitable for almost all 1/8-1/10 RC cars, such as Traxxas, Arrma, Losi, and so on.

Running speed: The discharge rate of 50C provides ample power. As long as you increase the throttle, the motor can draw a considerable amount of current from the battery, and it is no doubt that the instantaneous speed can reach 30+ mph. Similarly, high-rate batteries can improve the response speed of the server and make it more sensitive.

Running time: I run these packs almost every day and the 5200mah capacity will get you 20-30 minutes of running. Of course, the running time depends on how you drive, the road surface, etc.

Since this is a 2s (7.4V) battery, it is very suitable for Senton 4×4’s brushed power system, so you don’t have to worry about the heat from full-throttle burning out the motor or ESC.

Upgrade method 2: 3s lipo

If you want to run 3s or more to get more speed, you need to upgrade the powertrain and change the pinion first. The following is the high rate series battery designed by Ovonic for the Arrma car, which is one of the best choices for Senton 4×4 to run 3s lipo.

3S 5200mAh 80C Hardcase

Battery Upgrade Guide

  1. Before buying a battery, please check whether the size, plug, and voltage of the battery match the vehicle.
  2. Before running the lipo battery, please set the cut-off voltage to 3.2v-3.5v (per cell).
  3. The battery voltage should not be lower than 3.2v and not higher than 4.2v. Over-discharging and over-charging can damage the battery.
