FPV LiPo Batteries: The C-Rating Specs That Stop The Sag
Updated 2026-08-30 · By the SpecRiot Editors
An FPV LiPo battery is the chemical engine of every flight, and choosing the wrong C-rating or cell count is how flights end in a walk of shame. What you are buying is discharge capacity and voltage sag, not mAh on a label. Cell count. C-rating. Capacity. Connector. Here is what separates packs that punch through punch-outs from packs that sag when you need them most. As one racer put it: "A good LiPo gives you the flight. A sagging LiPo gives you a lesson."

What Actually Matters When You Compare Fpv Lipo Batteries
Cell count (S):4S (14.8V) suits 5-inch freestyle and racers. 6S (22.2V) is the modern power standard for 5-inch and larger. 1S-2S powers whoops. Cell count must match your quad's electronics, and it is not negotiable.
C-rating:C-rating is the sustained discharge multiplier. 130C-160C packs (Tattu R-Line) deliver punch for racing. C-rating is the spec that decides whether punch-outs punch or sag.
Capacity and weight:1300-1500mAh is the 5-inch sweet spot: enough flight time without bricking the quad. Graphene packs (Zeee) run cooler but heavier. Capacity is flight time, and flight time is grams you carry.
Connector:XT60 is the 4S-6S standard. Match your quad's plug before buying. A battery with the wrong connector is a brick until you buy an adapter.

1500mAh sweet spot for 5-inch
XT60 plugs into standard stacks
The Catch
4S is aging against 6S builds
Need a quality charger to match
Heavier than 1300mAh packs
The Bottom Line: The CNHL Black 1500mAh 4S is the freestyle workhorse pack: 130C of discharge in a 2-pack that keeps you flying between charges. It is the pack you buy in multiples because it never lets you down twice.
The Bottom Line: The Tattu R-Line is the racing battery the pros reach for: 160C discharge and 6S punch in a pack built for gates, not cruising. It is the pack that makes punch-outs feel like throttle, not hope.
The Bottom Line: The Zeee graphene pack is the budget freestyle value: two packs, XT60, and 120C for less than a single premium battery. It will not win a race. It will absolutely get you flying every day.
The C-rating multiplies capacity to give maximum discharge: a 1300mAh 100C pack delivers 130A. Higher C means more punch before voltage sag.
4S or 6S for a 5-inch quad?
6S is the modern standard for 5-inch: more headroom and less sag. 4S still flies great and is cheaper. Match the battery to what your ESC and motors are rated for.
How do I store LiPo batteries safely?
Store at 3.8V per cell in a fireproof bag or metal box, away from flammables. Never store full or fully drained. Storage voltage is the difference between a hobby and a house fire.
