GNB 380mAh 4S LiPo Battery
GNB 380mAh 4S LiPo Battery
This GNB 380mAh 4S LiPo battery brings 4S punch to a compact package sized for antweight builds. At 90C, it delivers the current your weapon motor and drive system need without the bulk of a larger pack, and a 1C to 5C charge rate means you’re not locked into one charger speed. LiHV chemistry packs more usable energy into the same size and weight as standard LiPo. The XT30U-F connector plugs straight into the ESCs you’re already running. Sold individually.

GNB 380mAh 4S LiPo Battery
GNB uses LiHV (high-voltage) LiPo chemistry in this 380mAh 4S pack, charging each cell to a higher voltage than standard LiPo. That translates into more usable energy in a size antweight builds can actually carry, not the extra weight a larger 4S pack demands.
Builders in our community reach for this exact GNB pack when an antweight build needs 4S voltage without the size and weight of a bigger battery. That’s not a marketing claim, it’s what’s actually getting run in the arena.
This pack ships with a black XH-JST 5P charge connector and black XT30U-F discharge connector, a visual cue that separates it from other GNB models at a glance when you’re sorting a pit box full of batteries. Every other GNB pack in this lineup uses white or yellow connectors, so black stands out fast when you’re grabbing a battery between matches.
Specs at a Glance
380mAh capacity, 4S1P configuration, 15.2V nominal, 90C continuous discharge, with a charge rate of 1C to 5C so you’re not locked into a single charger speed. Black XH-JST 5P charge connector, black XT30U-F discharge connector, ready to plug straight into the ESCs you’re already running. Measures 54.0mm x 17.0mm x 27.0mm (L x W x H) and weighs 43.0g.
Pair this pack with a charger rated for LiHV chemistry, like our C6D Battery Charger, which covers 2-4S packs and handles this battery without issue. Always follow standard LiPo storage and charging safety practices, and store it at a safe voltage when it’s not in regular use. Sold individually.
Safety Warning:
LiPo batteries carry real risk of fire if mishandled. Always charge on a fireproof surface, never leave a pack charging unattended, and use a charger rated for LiHV chemistry. Retire and dispose of any punctured, swollen, or otherwise damaged pack immediately.

What charger do I need for this battery?
Use a charger rated for LiHV (high-voltage) LiPo chemistry. A standard LiPo charger set to standard voltage will undercharge this pack and leave capacity on the table. Our C6D Battery Charger is LiHV-capable and covers 2-4S packs, so it's a solid match for this battery.
How should I store this battery when I'm not using it?
Store LiPo batteries at storage voltage (around 3.8V per cell) when they're sitting for extended periods, in a fireproof LiPo bag or container, away from extreme heat. Check out our combat robotics safety guide for our full LiPo safety guidance.
What do I do if the battery gets punctured or swells?
Retire and dispose of any damaged or swollen LiPo pack right away. Never charge or use a battery that's been punctured, swollen, or otherwise damaged.
Why is this rated 15.2V instead of the usual 14.8V for 4S?
This pack uses LiHV (high-voltage) LiPo chemistry, which runs at a higher per-cell voltage than standard LiPo. Standard 4S is 14.8V nominal; LiHV 4S is 15.2V nominal. Make sure your charger is rated for LiHV or you'll undercharge the pack.
