Here’s a roundup of all of the 1S, 2S, 3S, and 4S LiPo batteries I examined for micro drones (toothpicks and whoops) with capacities starting from 260mAh to 850mAh. Efficiency relies on voltage sag below fixed load, discharge price, true capability and worth, to find out that are one of the best in your tiny whoops and ultralight micro quads.

In case you are new to LiPo batteries, it’s best to positively take a look at my newbie’s tutorial on LiPos: https://oscarliang.com/lipo-battery-guide/.

Testing Methodology

To find out one of the best batteries, I targeted on two key efficiency indicators:

Capability: Measured by discharging batteries at a sluggish price (~2C) from full cost down to three.3V per cell to precisely gauge their power storage capabilities.
Voltage Sag: Assessed by discharging at a quicker price (~20C) from full cost to three.3V to guage their efficiency below load all through the discharge cycle.

In case you’re curious what testing gear I used, it was the SkyRC BD350 discharger.

C Score

C-Score is meant to be an indicator of the discharge efficiency of a LiPo battery. Nonetheless, the numbers offered by producers are sometimes inflated for advertising and marketing functions, it has develop into meaningless through the years. For this reason I’m conducting these exams myself to seek out out their precise efficiency.

LiPo or LiHV?

LiHV is a distinct sort of LiPo battery that enables charging as much as 4.35V per cell as a substitute of 4.20V. The principle benefit is that the marginally greater voltage at full cost can present further energy to your quad. From my private expertise, LiHV does provide extra energy within the first half of the discharge cycle, however within the second half, the efficiency is much like LiPo. Additionally LiHV is barely greater power density than typical LiPo, leading to a barely lighter pack for a similar capability. Nonetheless there’s concern in longevity of LiHV and the way they degrade quicker than LiPo. Study extra in my LiHV Testing: https://oscarliang.com/lihv-battery/

LiHV is common for small 1S batteries for Tiny Whoops (e.g., 1S 300mAh/450mAh). For something greater or with the next cell rely, conventional LiPo continues to be the popular alternative.

Ensure you are conscious of the kind of batteries you’re getting and cost/deal with them appropriately to keep away from hazard. Don’t overcharge regular LiPo to 4.35V, which may lead to a hearth.

Most 1S LiPo nowadays don’t have wires anymore, for the burden saving and decrease resistance. However you may admire the “prolonged” battery connector in these GNB 1S batteries, because it makes plugging in barely extra versatile. And but it’s lighter than the BetaFPV given the identical capability and efficiency. Nonetheless it’s fairly costly.

Max Discharge: 5/5
True Capability: 460mAh
Worth: 5/5

Top-of-the-line performers within the 2S LiPo testing, but it’s a couple of grams lighter and solely $10. That is my go-to 450mAh 2S should you’re cautious about much less recognized manufacturers like “XF Energy.”

GNB 2S 520mAh 80C HV

True Capability: 500mAh
Worth: 3/5

Regardless of being “80C” just like the 450mAh from GNB, this battery exhibits extra voltage sag in direction of the top of the pack. It’s barely heavier than the 450mAh model, suggesting both a decrease C-rating or capability. The capability check confirmed it’s about 20mAh brief. I’d suggest sticking with the 450mAh model for these searching for flight time.

True Capability: 475mAh
Worth: 5/5

This must be top-of-the-line worth 2S 450mAh I’ve examined thus far. It’s a barely greater battery than what it claims to be, possibly that’s why the discharge price is surprisingly excessive. It’s solely $9 and it comes with a stability lead protector. Thoughts you that is heavier than different odd 450mAh pack.

Crazypony 2S 450mAh

Specs:

Value: $11
Dimension: 18.5×13.5x60mm
