I would like to know too. I did notice the other day under load 3cells were green and 1 was yellow I don't recall the voltages. All 4 of our batteries run this hot
It is winter time in Australia at the moment and my battery' temperature would get up to 48 C after around 15 mins flight time. The outside temperature is mostly 12 C - 17 C now. Wondering if the battery gets this hot is normal because of all included goodies such as VPS, Lightbridge?
Oh okay. Thanks for letting me know. In this case, my temperature range is normal, isn't it? I also notice that P3 battery runs hotter than my previous P2 battery.LiPo's will always get warm when a decent load is applied. The 'goodies' aren't really responsible for this load, but the motors are. All four motors probably consume around 5-6A when hovering and up to 25A when at full throttle. In other words, they're pushing a lot of juice, which generates heat.

Ah so that is the reason why. I didn't condition my battery for the first 10 cycles. Been running them down to 20% - 30% ever since. I would condition my second battery then. Thanks for your advise!Totally normal. The P2 battery is probably nicely worn in, which means there's less resistance within the cells, so they run cooler. Your most likely comparing a brand new P3 LiPo that has yet to be broken in. This means that the resistance in each cell is much higher than if it had already been cycled several times down to 50%. After a new LiPo has been cycled several times, draining them down no further than 50%, they will have a much lower cell internal resistance, which allows them to run cooler when pushing the same amount of juice.
