Buying Guide

When it comes to finding the best 4s lipo battery for your Traxxas Xmaxx 8s, there are a few key features to consider. Here are some things to keep in mind:

Battery Capacity

The capacity of a battery is measured in milliamp hours (mAh). The higher the mAh rating, the longer the battery will last. When choosing a battery for your Traxxas Xmaxx 8s, it’s important to consider your specific needs. If you plan on running your truck for long periods of time, you’ll want a battery with a higher mAh rating. However, keep in mind that higher capacity batteries are often larger and heavier, which can affect the performance and handling of your truck.

Battery Voltage

The voltage of a battery is another important factor to consider. The Traxxas Xmaxx 8s requires a 4s lipo battery, which means it needs a battery with four cells. Each cell has a voltage of 3.7 volts, so a 4s battery has a total voltage of 14.8 volts. It’s important to choose a battery with the correct voltage to ensure proper performance and safety.

Battery Discharge Rate

The discharge rate of a battery is measured in “C” ratings. This refers to the rate at which the battery can safely discharge its energy. The Traxxas Xmaxx 8s requires a battery with a discharge rate of at least 50C to ensure proper performance. If you plan on running your truck at high speeds or performing stunts, you may want to consider a battery with an even higher discharge rate.

Battery Size and Weight

The size and weight of a battery can also affect the performance and handling of your Traxxas Xmaxx 8s. While larger batteries may have higher capacities, they can also be heavier and bulkier, which can affect the truck’s balance and maneuverability. It’s important to choose a battery that fits comfortably in your truck and doesn’t throw off its balance.

Brand and Price

Finally, when choosing a 4s lipo battery for your Traxxas Xmaxx 8s, it’s important to consider the brand and price. While there are many different brands and price points available, it’s important to choose a reputable brand that offers high-quality batteries. Don’t be swayed by extremely low prices, as these batteries may be of lower quality and could potentially be dangerous.

FAQs

How long does an 5000mAh 4S LiPo last in X-Maxx?

Expect about 12-15 minutes per 4S 5000mAh battery. Running dual packs wired as 8S will approximately double runtimes to 25-30 minutes. High speed runs drain packs quicker.

Can the X-Maxx use 3S batteries?

No, the X-Maxx requires the full 8S voltage of dual 4S LiPo packs wired in series. Dropping to 3S will result in low power. Only use specified 4S packs.

How many charges do 4S LiPos last?

When cared for, quality 4S packs will safely offer 300-500 charge cycles before dropping capacity necessitates retirement. Individual pack lifespan depends on usage and care.

What if Traxxas 4S packs don’t fit my X-Maxx?

Some X-Maxx models may require small foam or paper spacers to fit Traxxas’ 4S packs. Check battery compartment dimensions and compare to pack dimensions before purchase.

Can I use more than 2 LiPos in the X-Maxx?

No, only use the recommended 2 x 4S LiPo packs in series for 8S total voltage. Wiring 3+ batteries exceeds the X-Maxx’s electrical system capabilities and will cause issues.

Conclusion

A pair of high capacity and discharge 4S LiPo packs are essential for keeping your Traxxas X-Maxx fueled with 8S brute power. Just be sure to select quality batteries that fit while providing 50+C constant discharge rates from trusted brands.

With a couple of capable 4S 5000-6000mAh batteries always fully charged, you can unleash the X-Maxx’s outrageous backflipping, wheelie popping power again and again!
