May 13, 2026 by haiboxingrc
The stock battery of the MJX H18P is a 2S 7.4V 500mAh 20C LiPo battery, fitted with a JST PH2.0 connector (universal port for small-scale crawlers).
 
Its measured dimensions are approximately 55×30×12mm, with a weight of about 28–30g.

Recommended battery options

First choice: 600mAh

  • Almost the same size as the original, only 7g heavier. Runtime increases by 50% with no negative impact on vehicle performance — the best option for most users.

Second choice: 750mAh

  • Runtime improved by 80%, weight up by 17g. It fits perfectly inside the battery compartment and offers the best cost performance.

Not recommended: Over 800mAh

  • Batteries above 800mAh are either too long/tall to fit the battery compartment, or too heavy and will seriously affect the car’s balance.
If your battery makes the front end too heavy, you can add brass balance weights to keep the chassis balanced.
