Arrma 1/18 scale desert truck — Mojave Grom’s battery tray size is approximately 130 x 40mm (L x W). If you’re looking to go beyond the power provided by the stock battery for this RC truck, you’re in the right place. Here, I’ll recommend two of the best replacement 2s LiPo batteries. These batteries not only extend the runtime but also enhance the responsiveness and burst power. You can choose one based on your budget and personal preference.
A lot of people mistakenly think that EC2 is compatible with the IC2 connector! It’s not; we tried shoving it in, and there’s no way. So, I suggest you switch to deans connector or others.
