GNB 300mAh 4S LiPo Battery
GNB 300mAh 4S LiPo Battery
This GNB 300mAh 4S LiPo battery packs 4S voltage into a footprint built for antweight combat robots. At 80C, it delivers the current your drive and weapon systems need without the size of a larger pack, and a 1C to 5C charge rate keeps you flexible on 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 300mAh 4S LiPo Battery
GNB uses LiHV (high-voltage) LiPo chemistry in this 300mAh 4S pack, charging each cell to a higher voltage than standard LiPo. That translates into 4S voltage in a package that doesn’t outgrow an antweight chassis.
Builders in our community reach for this exact GNB pack when an antweight build needs 4S punch without the size and weight of a bigger battery, especially when the rest of the build is already tight on weight budget.
White XH-JST 5P charge connector and yellow XT30U-F discharge connector make this pack a straightforward swap into the ESCs and chargers antweight builders already run. At 36g, it weighs well under half of our 850mAh flagship pack, while still delivering full 4S voltage to your weapon and drive systems.
Specs at a Glance
300mAh capacity, 4S1P configuration, 15.2V nominal, 80C continuous discharge, with a charge rate of 1C to 5C so you’re not locked into a single charger speed. White XH-JST 5P charge connector, yellow XT30U-F discharge connector, ready to plug straight into the ESCs you’re already running. Measures 53.0mm x 17.0mm x 24.0mm (L x W x H) and weighs 36.0g, light enough that it won’t cut into your weapon or armor weight budget.
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.
