If you’re planning to fly your Black Horse PC-21 1962mm ARF with an electric setup, the battery choice isn’t just a technical detail—it’s the heart of how your flight feels. The PC-21 is big, beautifully built, and deserves packs that can actually keep up when you open the throttle. That means going with a 12S system: two matched 6S LiPos wired in series.
Over the last few months, we’ve seen a clear pattern among PC-21 flyers: they gravitate toward CNHL batteries that hit the sweet spot of punch, size, and heat management. Below are our top-tested picks, organized by what kind of pilot you are and what you want from each flight.
Recommended 6S Batteries for 12S Setup
- Everyday Performance: G+Plus 6000mAh 70C — If you want rock-steady voltage and smooth verticals without thinking twice about sag.
- Light & Responsive: G+Plus 5000mAh 70C — A solid pick for pilots who prefer to keep weight down for roll agility and tighter patterns.
- Great Value: Black Series 6000mAh 65C — Plenty of muscle for the price, and it flies cool even under long throttle pushes.
- Budget-Friendly Alternative: Black Series 5000mAh 65C — Lighter and more affordable if you’re happy to trade a bit of time in the air for price and balance.
- Maximum Punch: Racing Series 6200mAh 90C — Originally built for RC cars, but hits hard and flies fine—if you don’t mind the extra weight.
Why EC5 and 12S Make Sense Here
The PC-21 isn't light or forgiving—it needs current and plenty of it. EC5 plugs give a firm, heat-resistant connection and are a perfect match for 160A ESCs and 180Kv motors. Two 6S batteries give you the full 12S setup at 44.4V, which this plane eats up during sustained climbs or long pattern flights.
Fitment & Real-Life Balance
We've physically tested all these batteries in the PC-21's fuselage. The G+Plus 6000 fits snug and gives the best blend of run time and punch. The Black Series packs offer more flexibility for casual flights, and the Racing Series is heavier—but still flies strong if you're doing power-on verticals or big loops.
