LiPo batteries are also known as lithium-ion polymer batteries. These kind of batteries are rechargeable or secondary cell batteries. They are commonly utilized in phones, but can also be used in radio-controlled planes and other smaller electronics. These batteries may also be used someday to power electric cars.
Cold weather affects lipos, like other batteries, you will probably capacity to be down, and therefore duration to be down. If your model is set up to direct cooling air over the lipos in the summer then it'll supercool them in the winter time, unless you make a change. What I do is to put aluminium tape over the inlet ducts that are there to provide that cooling air.
The Lipos themselves sit in a Liposack, with a number of chemical handwarmers to keep the worst of the chill off. One of those will give about 30 minutes of decent heat and so four of them last about as long as I want to be out in the very low temperatures. On returning home the crystallised chemical handwarmers are warmed up in a pan of boiling water up and they then revert to their liquid state for the next time .
There is a way to get more performance out of a LiPo battery; optimize the Starting Temperature. LiPo batteries have an "ideal output temperature". The internal resistance is at its lowest when they're ran with a starting temperature of around 100°F (38°C). A pack at a temperature of less than 50°F (10°C) (very cold pack) can show noticeably poorer performance until it warms up with use. In the winter time or in cold climates, it's best to store packs in a heated indoor living space. For outdoor use in cold climates, you should pre-warm your packs to 90-100°F (32-38°C) before using them. But remember, 140°F (60°C) is the maximum safe temperature, and the pack's temperature will increase when it's used, so be careful not to pre-warm the pack up too much.
Tips for your Lipo batteries
There are a couple effective ways to do this. The most effective is to find a square heating pad that you can place in your battery bag at the bottom. The only issue here is you will need a power source, not always a choice when out on location.
The second method is the method I've used when I don't have access to the generator or another plug in. These tire heaters work perfect to plug into a small gens ace 2200mah 11.1v 30c and keep the batteries warm. Simply place your batteries on top of each element and choose a heat that won?ˉt melt the plastic. Also don't forget to keep an alarm on the Lipo batteries
Disclaimer: you must make sure to attach the sensor to one of the pads so they don't run on full power not stop. To do this, just poke two small holes through one of the pads and zip tie the sensor to it so it's secure.This will help keep your batteries warm while out in weather normally too cold for Lipo batteries.
