Best FPV LiPo battery packs for FPV drones – high discharge under $30

Recommendation

This Tattu 850mAh 4S 95C 15.2V HV LiPo (XT30) is a direct match if you need a compact, high-voltage 4S pack for micro/mini FPV builds that use an XT30 connector and benefit from LiHV charging. The 15.2V (LiHV) chemistry gives you a higher top voltage than standard LiPo, which translates to sharper throttle response and a bit more top-end power on the same motors. Why this is a strong choice: - High 95C rating delivers strong discharge capability for aggressive flight — 95C × 0.85Ah ≈ 80–81A continuous theoretical output, which is plenty for most 3"–4" setups. - XT30 connector keeps weight and resistance low for small quads, and Rotor Riot FPV is a reliable source; the product also has a 5/5 user rating (3 reviews), indicating solid real-world satisfaction. Budget fit: At $20.59 this pack is a very good value — typically at or below market price for branded 4S LiHV 850mAh cells. If you’re watching costs, this gives high performance without a premium price. Things to consider: - Charger compatibility: you must use a charger that supports LiHV (4.35V/cell) if you want the full voltage benefit; otherwise charge as standard LiPo (4.20V/cell) and expect slightly less performance. - Connector vs. current: XT30 connectors are usually rated ~30A continuous; the battery’s C rating implies much higher current potential — ensure your ESC/motor setup doesn’t continuously pull more than the connector’s safe rating (or consider an alternative connector or wiring). - Fit and weight: verify physical dimensions and mounting space in your frame and account for CG/flight-time tradeoff (850mAh gives moderate flight times). - Safety: always balance-charge, avoid charging unattended, store at storage voltage (~3.8V/cell), and retire any puffed/damaged cells.
