Finest LiPo Batteries for Micro FPV Drones (1S, 2S, 3S, 4S | 300mAh to 1000mAh)

19.9K

Here’s a roundup of all of the 1S, 2S, 3S, and 4S LiPo batteries I’ve examined for micro FPV drones, together with toothpicks and whoops, with capacities starting from 300mAh to 1000mAh. Efficiency (discharge functionality) is set by measuring voltage sag underneath fixed load. I additionally measure the true capability of every pack by discharging it slowly.

I preserve including new batteries to this database so you’ve a transparent benchmark for locating the most effective batteries on your tiny whoops and ultralight micro quads.

In case you are new to LiPo batteries, you need to undoubtedly try my newbie’s tutorial on LiPos: https://oscarliang.com/lipo-battery-guide/.

Testing Methodology

To find out the most effective batteries, I targeted on two key efficiency metrics:

Capability: Measured by discharging batteries at a sluggish charge (e.g 1C) from full cost down to three.3V per cell to precisely gauge their vitality storage capabilities.
Voltage Sag: Assessed by discharging at a quicker charge (e.g. 20C) from full cost to three.3V to judge their efficiency underneath load all through the discharge cycle.

C Score

Each LiPo battery has a C ranking printed on the label.

C-Score is meant to point the discharge efficiency of a LiPo battery. Nevertheless, the numbers supplied by producers are sometimes inflated for advertising and marketing functions, and through the years they’ve grow to be considerably meaningless. This is the reason I’m conducting these assessments myself to learn the way these batteries really carry out.

LiPo or LiHV?

LiHV is a unique kind of LiPo battery that enables charging as much as 4.35V per cell as an alternative of 4.20V. Whereas customary LiPo remains to be mainstream for larger quads like 5-inch and 7-inch, LiHV has grow to be the usual battery kind for micro quads due to the additional energy it’s supposed to supply.

From my private expertise, LiHV does provide extra energy within the first half of the discharge cycle because of the upper voltage, however efficiency within the second half is much like common LiPo because the voltage continues to drop. One other profit is that LiHV tends to have barely larger vitality density than typical LiPo, leading to a barely lighter pack for a similar capability.

Nevertheless, there are issues in regards to the longevity of LiHV and whether or not it degrades quicker than customary LiPo. I did some real-world testing to seek out out if that is true: https://oscarliang.com/lihv-battery/

For those who use each LiPo and LiHV, be sure you choose the right battery kind in your charger. Overcharging a traditional LiPo to 4.35V per cell could be harmful.

Most 1S LiPo today 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. Nevertheless it’s fairly costly.

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

This needs to be probably the greatest worth 2S 450mAh I’ve examined to this point. It’s a barely larger battery than what it claims to be, perhaps that’s why the discharge charge is surprisingly excessive. It’s solely $9 and it comes with a steadiness lead protector. Thoughts you that is heavier than different atypical 450mAh pack.

Crazypony 2S 450mAh

Similar efficiency to the 450mah variant, however being labelled as a 520mah, and solely 2 grams heavier made me marvel if that is too good to be true. And my testing did counsel it’s smaller than marketed – solely round 500mah. For an additional $2 you might be solely getting 50mah extra, you might be higher off getting the GNB 4S 450mah.
