Are you looking for the best replacement 2S LiPo for your Traxxas Mini Maxx? You’re in the right place! Here, we recommend 2 budget friendly options that fit perfectly in the mini Maxx battery tray and deliver even more punchout performance compared to the stock battery, letting you enjoy higher bashing thrills.
Tip: Mini Maxx Battery tray size is 113 x 41 x 22 mm (L x W x H)
Best Performance Battery

Gens ace 2200mah 2S 60C 7.4v Lipo with XT60 Connector
- Size: 87 x 34 x 20 mm
- Weight: 130g
Although this lipo has a lower mah compared to the stock, its 60C rating delivers higher wattage, enhancing the Mini Maxx’s bashing performance and providing consistent power in all terrain conditions.
Gensace lipos are unbeatable overall, IMO.
With balanced cells, test data shows a voltage gap of within 5mV between cells. This means no voltage sag throughout the entire run with the Mini Maxx.
BTW, LOW IR is another highlight. From my experience, this battery has never shown signs of overheating, and its capacity is closer to 2200mah.
Best Budget Battery

OVONIC 2200mah 2S 7.4V 50C Lipo with XT60+TRA Connector
- Size: 87 x 33 x 18 mm
- Weight: 118g
The price of this battery is about 1/3 of the stock. This means you can have multiple of these lipos, and they deliver higher punch to the Mini Maxx, making them a great alternative. Additionally, the build quality of these batteries is not comparable to poorly made packs — they are on par with major brands.
I own several of these packs and have accidentally over discharged them twice. After balancing charging, they came back to life and have lasted a long time. Even now, there’s no sign of power degradation.
2 Best Long Run Time Batteries

AMZZN 3500mah 2S 30C 7.4V Lipo With Deans Connector
- Size: 96 x 34 x 20 mm
- Weight: 117g

Sea Jump 3500mah 2S 35C 7.4V Lipo With Deans Connector
- Size: 97 x 34 x 20 mm
- Weight: 127g
Speed: Both batteries improve throttle and steering response, making the Mini Maxx more maneuverable. I was really impressed by the full-throttle speed runs and ramp sends.
Run Time: Comparable to the stock battery, offering around 30 to 60 min of run time, YMMV.
Battery Life: From my experience, these batteries held up through long, hard runs with excellent discharge consistency. As long as you don’t abuse them, they can last for over 200 cycles.
Compatibility: These compact batteries fit a wide range of popular small-scale vehicles, including the Arrma Grom series, Losi NASCAR, and Hyper Go.
About Connector
Since Deans and Traxxas connectors aren’t compatible, I recommend using an adapter or simply swapping out the connector.
If you’re planning to change the connector and don’t have prior experience, check out the video below to learn how to make the switch easily and safely.
Can I Use a 3S LiPo with 2S System?
It depends on the ESC. If your ESC is rated for a max of 2S LiPo, running a 3S LiPo will cause your system to overheat, potentially damaging the ESC and motor—even if you set the throttle limit. So, if you want to run a 3S LiPo in your Mini Maxx for better performance, consider upgrading the stock ESC and motor to handle 3S power.
