Overview
The Ovonic 2S LiPo battery set includes two 7.4V 750mAh packs (2S1P) designed for 1/18 RC cars and trucks that require a compact high-discharge battery. Each pack uses a Mini TRA discharge plug and a JST-XHR-3P balance/charge plug, and the set includes XT60-to-TRA adapter leads for convenient connection with compatible power setups.
Key Features
- 2S power system: 7.4V (2S1P) 750mAh LiPo packs with 50C continuous discharge rate.
- Compact size for tight battery trays: 53 x 29 x 15 mm (2.09 x 1.14 x 0.59 inch).
- Lightweight: 43 g (0.09 lb) per pack (variance: ±20 g stated).
- Wiring and plugs: 20 AWG wire, Mini TRA discharge plug, and JST-XHR-3P balance/charge plug.
- Manufacturer-stated cell construction comparison: “Stacking Technology” is presented vs “Winding Technology (Others)” with stated differences: higher energy density (+6%), longer running time (+12%), lower battery swelling (-8%), and lower internal resistance (-4%).

Details


Ovonic’s manufacturer-stated “stacking technology” is designed to improve energy density and runtime while reducing swelling and internal resistance versus typical winding construction.


Fitment comes down to the basics: confirm the 7.4V (2S) voltage, battery dimensions, and Mini TRA connector match your vehicle’s battery tray and plug.

Everything needed to get started is included: two 2S 750mAh packs plus two XT60-to-TRA adapter leads for compatible power setups.
