by Gens Ace

The Tattu 850mAh 11.1V 45C 3S1P LiPo Battery Pack with XT30 Plug (SKU: TAA8503S45X3 / TA-45C-850-3S1P-XT30) is a compact, high-efficiency power source engineered specifically for 150-size micro FPV quadcopters, 2.5-inch to 3-inch freestyle drones, and lightweight park flyers. Constructed with premium Japanese and Korean Lithium Polymer cell materials, this pack balances energy density, weight, and discharge performance to deliver reliable flight times and stable throttle response.

Delivering a 45C continuous discharge rate (90C burst) with 9.44Wh of total energy, the battery provides steady voltage holding under load while keeping all-up aircraft weight low at approximately 76 grams. Factory-terminated with an industry-standard XT30 connector on flexible silicone wire and a 4-pin JST-XHR balance connector, the Tattu 850mAh 3S 45C pack is designed for everyday freestyle sessions, indoor micro racing, and park cruising.

Key Features

• High-Density Stacking Technology: Utilizes single-cell stacking technology to achieve a true 850mAh capacity within a compact 60 mm form factor.

• 45C Continuous / 90C Max Burst Discharge: Delivers consistent voltage output and punch-out recovery without excessive voltage sag on micro brushless setups.

• Automatic Production Consistency: Manufactured on automated production lines to ensure matched internal resistance and cell capacity across all three cells.

• Factory-Fitted XT30 Plug: Pre-soldered low-resistance XT30 discharge connector minimizes electrical bottlenecks and handles continuous micro-drone current draws.

• Lightweight 76g Profile: Optimizes center of gravity (CG) and power-to-weight balance on 150-size micro quads and sub-250g builds.

• Standard JST-XHR-4P Balance Lead: Compatible with virtually all standard LiPo balance chargers and voltage checkers.
