BetaFPV LAVA 4S 550mAh 75C Battery (2PCS)

The BetaFPV LAVA 4S 550mAh 75C is a LiHV pack built with BetaFPV's Z-Folding cell construction for 2-inch to 3-inch micro freestyle quads and lightweight sub-250g builds. Compared with a conventional wound cell, the Z-Folding process gives roughly 5% higher energy density and a flatter discharge curve, so voltage holds up better under hard throttle.

Key features

• LiHV (high-voltage LiPo) chemistry charges to a higher per-cell voltage than standard LiPo, for more usable energy per pack.
• Z-Folding internal structure lowers internal resistance, giving around 0.2V higher discharge platform than a wound-cell pack at the same load.
• Sustained 75C discharge rate suits punchy micro freestyle flying without excessive voltage sag.
• Factory-fitted XT30 discharge lead (16AWG silicone wire) and a JST-XH balance plug.
• Sold as a pair, sized to match 1404-1504 class motors on 2 to 3 inch propellers.

Charge these as LiHV packs on a charger profile that supports the higher per-cell voltage — treating them as standard LiPo will leave capacity on the table.
