GNB 550mAh 2S1P 7.4V 70C Lipo Battery - Micro FPV Whoop Pack with XT30 Connector

The GNB 550mAh 2S1P 7.4V 70C Lipo Battery provides the perfect sweet spot between structural weight reduction and punchy power output for competitive indoor racing and micro outdoor freestyle platforms.

Reliable 70C Discharge & Stable Power Delivery :

Featuring premium matched cells, this 2S battery pack sustains a true 70C continuous current delivery. It handles power surges up to 140C cleanly, ensuring minimal voltage sag during sudden vertical punch-outs or fast recoveries while maintaining steady throttle control all the way to the end of the pack.

Ultra-Lightweight & Agile Form Factor :

When building high-performance micro multirotors, every gram matters. Weighing in at just 29 grams, this battery pack keeps your total weight exceptionally low, boosting your drone's power-to-weight ratio to maximize flying agility, reduce motor heat, and lengthen flight times.

Durable Wiring and XT30 Interface :

To guarantee efficient power delivery without creating resistance bottlenecks, the pack is pre-soldered with heavy-duty 20AWG high-flex silicone wire. It includes a reliable XT30 discharge connector alongside a standard JST-XH balance lead for safe, accurate cell monitoring during charging.

Frequently Asked Questions :

Q1: Can I charge this 2S battery pack using a basic 1S USB whoop charger?

Ans: No, this is a 2S (7.4V) battery pack. You must use a dedicated LiPo balance charger that features a 2S balance port (JST-XH) and an XT30 charging lead to charge both internal cells safely and evenly.

Q2: What is the ideal charge rate to keep this battery pack healthy?

Ans: For maximum cycle life and long-term health, we recommend balance charging at 1C (0.55A) to 2C (1.1A). If you are in a rush at the field, it can safely handle fast charging up to 5C (2.75A) with an intelligent charger.

Q3: How low can I safely drain this battery during micro FPV flights?

Ans: To prevent permanent damage to the cell chemistry, you should set your Betaflight low voltage alert to 3.5V per cell (7.0V total for 2S) and land immediately before the resting voltage drops below 3.3V per cell.

Q4: Will this battery package slide straight into a standard blocky battery tray?

Ans: The pack features a standard flat layout measuring 13mm x 18mm x 60mm. It fits comfortably inside most generic 2S micro whoop trays, adjustable elastic straps, and 3D-printed battery mounts.
