An FPV quadcopter's battery has a tough job. A racing drone or freestyle quadcopter demands a huge amount of power. The best batteries can deliver this power without damaging themselves in the process.

Batteries come in different voltages, indicated by their S-rating. 4S batteries are the standard for mini quads. Some beginners choose to start on 3S because the slight reduction in power makes it easier to learn. Personally, I think this is a waste, because most beginners quickly outgrow the 3S batteries. Spend an extra few hours practicing on a simulator instead of buying 3S batteries. That's why there are only 4S batteries on this list.

It's impossible to tell from marketing which batteries are the best. C-rating is supposed to indicate a battery's ability to deliver current, but there is no standard way of determining C-rating, so many manufacturers basically make it up. Capacity, measured in milliamp-hours (mAh) is like the size of a car's gas tank. But bigger batteries don't always mean longer flight times, because they're also heavier. And heavier batteries make the quad handle worse. The good news is, I've done a lot of real-world testing, so I know which of batteries are worth having. Here they are!

The best value: Ovonic 1300mAh 4S 100C lipo

Ovonic battery is a new brand, offer the best value RC hobby batteries. 1300mAh 4S lipo battery with amazing performance and reliablity. Compared to a similar mAh battery from another vendor, the Ovonic will be smaller and lighter. It's similar with Tattu brand, but Ovonic price is affordable. The best value brand. Only $15.69 on AMPOW.

Top of the line: Tattu R-Line 4S 1550 mAh 95C.

Tattu makes some of the best batteries for FPV drone racing and freestyle, period. Everybody puts "95C" discharge rating on their label. Tattu R-Line batteries come as close as anybody to actually achieving it.

These batteries cost more than twice as much as the budget batteries in this list. But if you fly the fastest and most powerful mini quads, then buying a lesser battery is literally throwing money away. Not just because the cheap battery will disappoint you, but because it will literally destroy itself trying (and failing) to deliver the massive power that the high-end quad demands. $28.99 now on genstattu. 

The higher performance: Ovonic 1550mAh 4S 100C battery

This is the new OVONIC 7.4V 5000mAh 50C 2S LiPo battery pack from Ampow.

The battery is a standard “stick pack” with dimensions of 137mm x 45mm x 24mm and weighs in at 302 grams.

This OVONIC pack is ideal 1/10-scale off-road vehicles which use a full-length battery pack (such as short course trucks, monster trucks, and rock crawlers).

This battery pack provided ample run-time in our Traxxas 2wd Slash with a modified motor, and remains well balanced and consistent charge after charge.
