Best Performance Battery
Gens ace 2200mAh 2S 60C 7.4V Lipo with XT60 Connector

Highlight: High punch | Non-voltage sag | Long battery life
Looking to upgrade your NASCAR’s throttle response and driving performance? Then this high-discharge Gens ace 2S LiPo is your best choice.
Gens ace stands for quality and reliability. Unlike other brands, the C-rate and capacity of this battery are closer to what they promise, giving you the power and performance you need.
The 60C discharge rate significantly boosts your punch-out performance, delivering constant power even when you keep pulling the trigger hard. Thanks to its consistent discharge curve and zero voltage drop, you’ll experience seamless speed runs.
Compared to a standard stock lipo, this 2200mAh pack extends your run time by almost 60%, allowing you to have fun for an 30 to 60 min, YMMV.
Best Budget Battery
Zeee 2200mAh 2S 50C 7.4V Lipo with Deans Connector
- Size: 73 x 34 x 18.5 mm

If Gens ace is my top pick for performance, then Zeee is my go-to for budget.
The 50C rating noticeably improves your NASCAR’s maneuverability and acceleration, bringing my car back to life and putting a big smile on my kids’ faces—moments I won’t forget.
You might notice that compared to other 2S LiPos of similar capacity, this battery is compact and lightweight. Yes, I love it for that! It’s also a great fit for my 1/16 and 1/18 scale trucks and crawlers.
Have you ever experienced batteries failing after just a few runs? Worry no more! As long as you use it correctly, this battery can last over 200 cycles.
Longest Run Time Battery
Sea Jump 3500mAh 2s 35C 7.4V Lipo with Deans Connector
- Size: 97 x 34 x 20 mm
- Weight: 127g
Highlight: Long run time
This 3500mAh pack is the highest-capacity 2S LiPo battery you can find for NASCAR. It lasts through extended street runs, and when fully charged, it can keep you enjoying a full afternoon of fun without needing another recharge.
To be honest, while it may not be as well-known as Gens ace or Zeee, this battery offers not bad performance, making it a great option if your priority is runtime.
BTW, the package includes 2 simple chargers, which is a nice addition for those who don’t already have one.
Tip: These connectors (including EC2) are not compatible with IC2. So, you’ll need to use an adapter or replace the connector. If that sounds like a hassle, the Spektrum 1400mAh 2S LiPo with IC2 connector might not be a bad option.
