Finest LiPo Batteries for Micro FPV Drones (1S 2S 3S 4S 300mah 450mah 550mah 750mah 850mAh)

[ad_1]

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 below load, discharge charge, 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, you need 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 targeted on two key efficiency indicators:

  • Capability: Measured by discharging batteries at a gradual charge (~2C) 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 (~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. Nevertheless, the numbers supplied by producers are sometimes inflated for advertising functions, it has grow to be meaningless through the years. This is the reason 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 enables charging as much as 4.35V per cell as an alternative of 4.20V. The primary benefit is that the marginally larger voltage at full cost can present a bit extra energy to your quad. From my private expertise, LiHV does provide extra energy within the first half of the discharge cycle, however after that, the efficiency is much like LiPo.

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

Be sure to 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 might lead to a fireplace.
