Here’s a roundup of all of the 1S, 2S, 3S, and 4S LiPo batteries I examined for micro drones with capacities starting from 250mAh to 850mAh. Efficiency is predicated on voltage sag underneath load, discharge price, true capability and worth, to find out that are one of the best on your tiny whoops, toothpicks and micro quads.
If you’re new to LiPo batteries, it is best to undoubtedly try my newbie’s tutorial on LiPos: https://oscarliang.com/lipo-battery-guide/.
Testing Methodology
To find out one of the best batteries, I centered on two key efficiency indicators:
- Capability: Measured by discharging batteries at a gradual 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 underneath 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. Nevertheless, the numbers supplied by producers are sometimes inflated for advertising and marketing functions, it has turn out to be meaningless through the years. That is why I’m conducting these checks myself to seek out out their precise efficiency.
LiPo or LiHV?
LiHV is a unique sort of LiPo battery that permits charging as much as 4.35V per cell as an alternative of 4.20V. The principle benefit is that the marginally greater voltage at full cost can present a bit extra energy to your quad. From my private expertise, LiHV does supply extra energy within the first half of the discharge cycle, however after that, the efficiency is just like LiPo.
LiHV is in style for small 1S batteries for Tiny Whoops (e.g., 1S 300mAh/450mAh). For something greater or with a better cell depend, conventional LiPo remains to be the popular selection.
Ensure you are conscious of the kind of batteries you’re getting and cost/deal with them accurately to keep away from hazard. Don’t overcharge regular LiPo to 4.35V, which may end in a fireplace.
