2S LiPo Batteries

Also in 2S LiPo Batteries, currently out of stock
2S LiPo batteries are two-cell 7.4V packs (7.6V for LiHV) used on 2-inch and 2.5-inch micro quads, toothpicks and the larger 75–85mm whoops that have moved past 1S. This page collects every 2S pack in our LiPo Batteries range. Capacity sets flight time against weight, which matters more on a sub-100g quad than on anything bigger, so start there, then check the connector — XT30 on most, a few micro plugs on the smallest — and that the C rating covers your motors.
How to choose a 2S LiPo
A 2.5-inch toothpick usually flies 450–650mAh, a 2-inch micro or 85mm whoop 300–560mAh, and 750–1000mAh 2S packs suit long-range toothpicks and small fixed-wings where flight time beats agility.
- Capacity (mAh): the dominant weight on a micro quad; a 100mAh step is noticeable.
- Discharge rating (C): a 560mAh 150C pack is rated for 84A continuous, far above what a 2S build draws, so lean towards weight and internal resistance rather than headline C.
- LiPo vs LiHV: HV packs (4.35V per cell) give more punch at the top of the pack; they need a charger with an HV mode.
- Connector: XT30 is standard; some Flywoo packs use the XT30UP variant, which is XT30-compatible.
What we stock
DOGCOM 560mAh 150C and 450mAh HV 100C on XT30, GNB (GAONENG) 880mAh 160C and 930mAh 120C, Flywoo Explorer 750mAh LiHV 80C two-packs and the Explorer 1000mAh for long range, the BetaFPV LAVA II 680mAh, and the iFlight Defender 900mAh pack in its 2S version. The RadioMaster 2S 7.4V 6200mAh pack is a transmitter battery for TX16S-class radios, not a flight pack.
Compatibility
A 2S pack is 7.4V nominal and 8.4V full (8.7V LiHV). Motors for 2S micro builds run 4500–7000KV on 2–2.5 inch props; a 1S whoop motor at 19000KV or more will burn out on 2S, and a 4S motor will feel weak. Check the AIO flight controller is rated for 2S input — many whoop boards are 1S only, while 2S boards usually accept 2–3S or 2–4S.
Charge at 1C with a 2S balance lead and store at 3.8V per cell (7.6V).
Frequently asked questions
- What is a 2S LiPo battery?
- A two-cell lithium-polymer pack, 7.4V nominal and 8.4V fully charged (8.7V for LiHV). Used on 2 to 2.5-inch micro FPV drones, toothpicks and 2S whoops.
- Can I run a 2S battery on a 1S whoop?
- Not unless the flight controller and motors are rated for 2S. Standard 1S whoop electronics will fail on 7.4V; look for a board and motors sold as 1–2S or 2S.
- How long does a 2S 450mAh pack fly?
- Around 3–5 minutes on a 2-inch micro depending on how hard you fly; 750–1000mAh packs on a toothpick can reach 8–12 minutes of cruising.
