CNHL 2200mAh 3S Lipo Battery 30C 11.1V lipo Battery with XT60 Plug for RC Airplane Car Truggy Truck Crawler(2 Packs)

Light weight, lasted well. Good price

注文してすぐ到着したのはよかったのですが、商品を見て？？？３Sの30C商品のはずが１個は40Cの表示　1個だけ40Cかな？購入したバッテリーは飛行機に積もうと軽いバッテリーを選択したのですが実際量ってみると180ℊを超えてました。余りにも誤差？が有りすぎ！！それとも重たいので40Cかな？商品説明と全く違います。飛行機が20ℊ程重くなります。小型飛行機なので20ℊはチョットきついかな。まあ、安いのでしかたないですかね。

I can’t comment on longevity because I haven’t owned them that long ask for power these batteries last quite a while not only my airplanes but in my cars which is a great thing when it comes to batteries, I’m sure as long as I charge them responsibly and then set them for storage. If I’m not gonna use them, they should last quite a while. Definitely worth the money.

I doubt I got two bad batteries, rather just not as much capacity as advertised.Specs wise, these are nearly identical to the horizon/spektrum batteries I refuse to buy, so I figured I’d save some money. Doing so means shorter flight times though.Initial impressions: great! Physically, excellent quality. All cells were perfectly balanced, at storage charge of 3.85v/cell and low Ir of less than 10. So far, very happy. They charged well.I always cycle my packs when I first get them. Charge to full (4.2v/cell) then down to 3.7v/cell. Tonight I happened to charge back up to 4.2v/cell then put them into storage charge of 3.85v/cell. I happened to pay attention to the mah “burned” and the ~45% discharge from 100% reported only 712mah. That would make the total capacity to be 1582.22mah, or 700mah less than the 2200mah advertised.Maybe my method is wrong, but it’s never failed me in the past, and have verified it’s accuracy with my gens ace batteries successfully.If you don’t mind the lesser capacity than advertised, then these are good value, but they weigh the same as packs that actually hold the capacity advertised, so in my case, less flight time. Oh well, I’ll keep these, but probably just continue to buy known good brands, or buy these for sacrificing.

Works as intended, make sure you research what it takes to use LiPo batteries. If you’re new to RC and LiPo, THESE ARE NOT PLUG AND PLAY. You’ll need a good Lipo Charger, preferably with a digital screen, a Lipo Safe bag, and you’ll probably need a volt meter/tester as well. Check YouTube videos on beginners guide to LiPo batteries. They’re well worth it, but it’s not as simple as plug, play, recharge without a few extra safety steps.
