Battery Load Test Comparisons - RC Groups
Nov 10, 2024 · Storage Facts: 1. Regarding maximum cycle life there is little difference storing packs between 3.7v/cell - 3.9v/cell if kept within 32F/0C - 68F/20C degrees. 2. Regarding reducing age related capacity reduction store at 3.7v-3.75v/cell and maintain temperature between 32F/0C - 68F/20C degrees. 3.
LiPo: How low can you go? (voltage per cell) - RC Groups
Oct 14, 2013 · Steve. Like Steve said, a battery voltage of 3.7V/cell (unloaded) tells you that you have used 80% of the batteries capacity. Most manufacturers recommend not discharging below 80% so your answer is any flying time that results in …
difference between a 30C and a 50C lipo battery - RC Groups
Apr 2, 2017 · difference C rating 30 and 50 C. The 50C battery would be capable of delivering more current than 30C one, if needed. However, if nothing else in your power system has changed, it will draw the same current as before. You have some extra current capability, which you are not using, so you will not see any difference in flying or charging times.
20C, 30C, 30C LiPo What's the difference? - RC Groups
Feb 2, 2013 · For example, a 2200 mAh lipo pack with a 30C rating is supposed to be able to support 2200mAh (or 2.2Ah) X 30 load which is 66 amps. Note, running at 30C means that the battery will not last for long! Capacity is rated in mAh or Ah and the "h" part means "hour". there are 60 minutes is an hour and 60 / 30 (the 30 is running a lipo at 30C) = 2 ...
How to match lipo to brushless motor - RC Groups
Jun 13, 2013 · You must know two things about your motor: voltage and Amp draw at this voltage. Then choose a battery at this voltage WHILE BIG ENOUGH to sustain the Amps. VOLTAGE: LiPos are made from series of cells of 3,7 V each. Therefore a "2S" LiPo means "2 cells in series" and it is 3,7 + 3,7 = 7,4 Volts. A 3S LiPo is 11.1V,
What are LiPo Internal Resistance "normal" values?
Dec 4, 2015 · The batteries were about 3.8v per cell, but the internal resistance has me a bit concerned. Battery-1 has the following per-cell readings: 7 - 5 - 6 mΩ. 3.80 - 3.82 - 3.86 Volts. Battery-2 has the following per-cell readings: 12 - 6 - 6 mΩ. 3.86 - 3.86 - 3.80 Volts. The first battery seems fine, but 12 mΩ reading on Battery-2, Cell-1 seems ...
Degassing a Puffy LiPo - RC Groups
Jun 11, 2010 · 1) Pinhole the outer bag without touching the inner brick. 2) Squeeze it flat. 3) Seal the hole. Now, I know there will be a bunch of folks who say "Don't Try It"! just based on general paranoia around LiPo batteries. So, let's assume that I have a totally safe place to charge, store, transport this pack.
Smallest 3S LiPo battery - RC Groups
Oct 3, 2020 · The battery shown for reference is a 3S 2200mAh LiPo. This is the battery that triggered me to ask the question. I like your suggestion to use three individual batteries for installation into nooks and crannies.
LIPO Low Voltage Setting - RC Groups
Nov 28, 2017 · The receiver, in turn, sends the voltage signal, via telemetry to the transmitter. For a 4S battery, I set the LOW voltage alarm at 15.2 volts (3.8 volts/cell) and the CRITICAL alarm at 10.8 volts (3.6 volts/cell). This sounds good in theory but under load, the battery voltage drops and I get constant low alarms - even at the start of a flight.
Horizon Hobby Spektrum Smart Technology Products Review
Sep 7, 2019 · Discharged LiPo batteries are not happy and fully charged LiPo batteries are not happy. The longer a LiPo battery is unhappy, the puffier they get. Our Club recommends storing LiPo batteries between 3.80 and 3.85 Volts per cell. We also recommend balance charging and balance discharging for all LiPo battery packs.
