The GENS ACE Adventure 2S 400mAh 7.4V 35C LiPo Battery (GEA354002SJS)​​​​​ is the primary battery matching these exact specifications, equipped with a JST-PH2.0 discharge connector for 1/24-scale crawlers like the Axial SCX24. 
If you need a standard red JST plug instead of PH2.0, you will need to check the connector style carefully, as "JST" is used for both on micro packs.
Direct drop-in replacement for the Axial SCX24 and similar micro crawlers (46 × 19 × 11.3 mm, 17 g).
