HCL-HP 3400mAh 4S LiPo Battery: More Send, Less Sag

Let's be real, your 'long-range' flights are currently shorter than the average TikTok video. This HCL-HP 3400mAh 4S LiPo battery is here to stage an intervention. Designed for UK pilots who measure flight time in minutes, not seconds, this high performance LiPo packs a serious punch without the weight penalty. It's the ideal long range FPV battery for cinematic cruises over the Peak District or questionable dives down the side of your office block.

Why You Want It

Because you're sick of voltage sag turning your epic power loop into a sad, gravity-assisted tumble. HCL-HP uses 100% Lithium Cobalt Oxide (LCO) cathodes—which is just a science-y way of saying these cells hold their voltage better under load. You get the consistent power to nail that gap, without bolting a house brick to your quad. Yes, we're asking you to empty your wallet, but in return, you get to trust physics for a change.

Specifications

• Capacity: 3400mAh (Give or take 5%, because our measurement tools are only human. Ish.)
• Voltage: 14.8V / 4S (Four cells of pure, unadulterated 'send it' juice.)
• Weight: 342g (The approximate cost of defying gravity.)
• Dimensions: 26mm x 45mm x 141mm (Measure your frame. Then measure it again.)
• Discharge Rate: 80C (A number so optimistic, it should run for parliament.)
• Wire: 12AWG (Thick enough to handle your questionable throttle habits.)
• Chemistry: Standard LiPo (Charge to 4.20V per cell. This is NOT LiHV. Don't be that person.)
• Connector: XT60 (The beige Toyota Corolla of FPV plugs. It just works.)
