GNB 380mAh 3S LiPo Battery (Long)
GNB 380mAh 3S LiPo Battery (Long)
GNB 380mAh 3S LiPo battery packs are built for combat robots that need steady power in a slim, long-format footprint. At 60C, this pack handles antweight and fairyweight drive systems without breaking a sweat, and it’s the long-format profile combat robotics builders reach for when chassis space is tight. LiHV chemistry means more usable energy in the same physical size as a standard LiPo. The XT30U-F connector plugs straight into the ESCs you’re already running. Sold individually.

GNB 380mAh 3S LiPo Battery (Long)
This GNB 380mAh 3S LiPo battery has been a fixture in combat robotics builds for years, not a new arrival hoping to earn trust. Builders in our community report running this exact pack season after season, which says more about real-world reliability than any spec sheet can.
GNB uses LiHV (high-voltage) LiPo chemistry in this pack, charging each cell to a higher voltage than standard LiPo. That means more usable energy packed into the same physical footprint, valuable when your build has limited space for a battery bay.
The long, narrow profile is a deliberate design choice, not a compromise. It slots into chassis layouts where a standard-profile pack won’t fit, without giving up capacity or discharge rate, a real advantage in antweight and fairyweight chassis where battery bay space is often the tightest constraint in the whole build.
Specs at a Glance
380mAh capacity, 3S1P configuration, 11.4V nominal, 60C continuous discharge, with a charge rate of 1C to 5C so you’re not locked into a single charger speed. White XH-JST 4P charge connector, yellow XT30U-F discharge connector, ready to plug straight into the ESCs you’re already running. Measures 68.0mm x 12.0mm x 20.0mm (L x W x H) and weighs 27.0g.
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 11.4V instead of the usual 11.1V for 3S?
This pack uses LiHV (high-voltage) LiPo chemistry, which runs at a higher per-cell voltage than standard LiPo. Standard 3S is 11.1V nominal; LiHV 3S is 11.4V nominal. Make sure your charger is rated for LiHV or you'll undercharge the pack.
