Description

Some aircraft are built to be felt, not seen. The Micro Volt twin pack feeds that kind of machine: a 4S 14.8V cell block that weighs 62 grams and disappears inside a mini quad frame, delivering 70C of continuous current the moment the throttle opens.

Everything about this pack is scaled for the small-format FPV world. The XT30U connector is the standard for micro builds, the JST/XH balance lead keeps cell monitoring simple, and the 450mAh capacity sits in the sweet spot where run time meets agility. Automatic stacking technology keeps internal resistance low and cell-to-cell consistency high, which is exactly what a 5-inch racer or a 3-inch freestyle quad needs when every burst matters.

Charge it at up to 5C between flights and the 140C burst rating will be waiting when you need a sudden climb or a hard recovery. Twin-pack delivery means the second flight is never more than a connector swap away.

RC pilots learn early that pack condition is everything: a tired cell sags under load, the quad falls out of a punch, and the flight is over before the timer says so. The Micro Volt is engineered to stay consistent, with matched internal resistance across all four cells and a discharge curve that holds voltage deep into the pack. For racers running heat after heat, that predictability is worth more than a few grams of marketing weight.

Great speed hides in small packages.

Application Scenarios

Built for mini quad racers, 3-inch freestyle quads, small FPV planes, and indoor micro builds where size and weight dominate the design. Club racers keep a rotation of these packs to stay in the air through practice sessions, while freestyle pilots value the instant punch for power loops and split-S recoveries. The 62g weight also suits lightweight camera drones that need to stay agile with a tiny action camera aboard.

Frequently Asked Questions

Q: What aircraft is this pack designed for?

A: Mini and micro quads using 4S with an XT30U connector, including 3-inch freestyle quads and lightweight FPV planes. Confirm your frame bay fits 30 x 18 x 65 mm before ordering.

Q: How fast can I charge it?

A: Up to 5C, which is 2.25A for a 450mAh pack. Use a balance charger and always monitor the pack while charging.

Q: Can I fly it in a 5-inch quad?

A: Possible if the frame accepts 4S and an XT30U plug, but most 5-inch builds prefer larger packs. This one shines in the 3-inch class.

Q: Why is a balance lead important?

A: It lets the charger read each cell individually, preventing overcharge of any single cell. That is the main cause of LiPo swelling and early failure.

Q: Do I need to break the pack in?

A: A gentle first cycle (charge at 1C, avoid full throttle) helps the cells settle. After that, normal 5C charging and full-throttle flying are fine.

Q: How do I store it between sessions?

A: At 3.7-3.85V per cell, in a LiPo-safe bag in a cool place. Never leave a fully charged pack sitting for more than a couple of days.

Q: What is the C rating actually telling me?

A: The C rating is the discharge multiple of capacity: at 70C, a 450mAh pack can deliver up to 31.5A continuously. It tells you whether the pack can feed your motor and ESC combination without sagging.

Q: Can I parallel-charge two of these packs?

A: Yes, with a parallel charging board rated for 4S, as long as both packs are at nearly identical voltages. Balance-charge them in parallel mode and never mix packs with different charge states.

Q: How do I know when the pack is worn out?

A: When it swells, loses runtime noticeably, or takes visibly longer to balance, retire it. A worn LiPo is a fire risk and should be recycled properly.

XT30U fits my build perfectly

Bought these for my mini racer and they fit without any adapter. The 140C burst helps my punch-outs on the back straight. Highly recommend.

Fast charge, great consistency

Charging at 2.25A is quick and the cells stay balanced across both packs. No puffing after a month of hard flying. Solid value.

Perfect for 3-inch quads

Slots right into the frame bay and the weight keeps the quad agile. Two packs in the box means double the flight time. Would buy again.

Tiny pack, huge punch

62 grams and it still delivers 70C without breaking a sweat. My 3-inch freestyle quad has never felt this responsive. XT30U plug matched my build exactly.
