GNB 850mAh 4S LiPo Battery
GNB 850mAh 4S LiPo Battery
This GNB 850mAh 4S LiPo battery dumps serious current without sagging when your beetleweight needs it most. At 120C, it’s built for hard-hitting weapon systems and aggressive drive setups alike, and it’s a pack combat robotics builders already trust. LiHV chemistry packs more usable energy into the same size and weight as standard LiPo, so you’re not carrying dead weight your bot doesn’t need. The XT30U-F connector plugs straight into the ESCs you’re already running. Sold individually.

GNB 850mAh 4S LiPo Battery
This GNB 850mAh 4S LiPo battery is built for combat robots that need to hit hard and drive harder. At 120C continuous discharge, it delivers the current beetleweight weapon motors and drive systems demand, without the voltage sag that costs you torque right when you need it most.
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 size and weight, so your build carries more punch per gram instead of dead battery mass. In an arena where every ounce goes toward armor, drivetrain, or weapon, that difference adds up fast.
Combat robotics builders in our community have been running this exact pack for years. Its yellow-and-black “flower pack” wrap is a familiar sight in beetleweight pits, and it’s earned a real reputation as a go-to choice for drive and weapon systems alike.
Specs at a Glance
850mAh capacity, 4S1P configuration, 15.2V nominal, 120C 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 63.0mm x 30.0mm x 26.5mm (L x W x H) and weighs 88.0g, light enough that it won’t eat into your weapon or armor budget.
Pair this pack with a compatible charger rated for LiHV chemistry, and always follow standard LiPo storage and charging safety practices. 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.
