Crazepony 400mAh 2S LiPo Battery with JST – 7.4V 30C for Micro FPV Racing Drones

Compact Power for Micro FPV Drones

The Crazepony 400mAh 2S LiPo battery is built for lean, agile micro quadcopters. Weighing about 22 g and measuring 1.5 x 0.75 x 0.75 inches, it fits tight airframes without sacrificing usable capacity. This tiny pack is especially well-suited for popular micro frames like the EMAX BabyHawk Mantis 85 DM007, where every gram matters and clean power delivery matters in rapid, high-contrast flight paths.

Key benefits at a glance

• Lightweight and compact: roughly 22 g with a very small footprint that suits micro builds.
• JST plug for straightforward setup on micro FPV drones, enabling quick swaps between flight packs.
• Discharge rating of 30–60C supports steady power during bursts and climbs, helping maintain responsive control.
• Designed for 1104 motors, with potential for improved flight duration in steady-state conditions.
• Simple safety guidance: avoid over-charge/over-discharge, hot environments, and water exposure; contact support if needed.

Real-world use cases

Picture a sunny afternoon race where a lighter, more responsive micro quad helps you weave between obstacles with fluid control. The 400mAh pack’s small size reduces airframe mass, while the JST connection keeps setup time short so you can test alternate flight configurations quickly. Pilots may notice smoother throttle response and a steadier power curve during fast transitions, especially on setups utilizing 1104 motors.

What to expect in practice

• Potentially up to about 30 seconds of extra steady-flight time under typical micro FPV conditions when paired with compatible motors and propellers.
• Appropriate for flight sessions that prioritize nimble handling and compact build volume.

Usage tips and care

Charge and store the battery as recommended, avoid exposing it to high temperatures, and do not use it if you notice any puffing or DOA symptoms. If you ever need assistance, our support team is available to help you with setup or compatibility questions.

Bottom line

This Crazepony battery offers a practical balance of light weight, easy integration, and confident power delivery for micro FPV racing drones. It’s a viable choice for pilots seeking a compact pack that complements a lean, responsive airframe without compromising on performance.
