No, the batteries are too small, you need at least a 5000mah 2s lipo with an ec3 connector. It comes with a 3300mah nimh but it has a bad wall charger. A LiPo like these would work, you would also need an ec3 charging lead for your charger.
With Traxxas, I wouldn’t recommend the 2wd line, my Slash 2wd required tons of RPM upgrades to be slightly more durable than my Typhon 3s. Even then, the Slash is still weaker than the Typhon in terms of traction and stability. The 2wd line is terrible for beginners.
My Slash has brand new...
Arrma Typhon or Granite Mega if you can stretch your budget a little. It comes with all of the stuff needed to run. It’s super durable, and has a throttle dual rate selector that you can bring down to 50% speed.
Yes, that charger has a storage charge option. Use it when you won’t be using the LiPo for more than a day. Never leave a LiPo fully charged for more than a day.
I would fix it and make a speed run car out of it. I heard the WLToys are not good for bashing, more for speed running. If you don’t have a proper LiPo charger, get one as soon as possible. After running the RC, and you aren’t going to be using it for more than a day, storage charge it.
