I put mine in a cooler with a heating pad (the kind for sore muscles) set on medium. Older heating pads did not have a safety timer built in so they stay on new ones turn off after a while.

Hello Peter,
35-40C is a good target. Try to stay below 45degC max. I use home heating pads like this when I have AC power: https://www.sunbeam.com/pain-relief...ing-pad-with-compact-storage/SAP_2139885.html
Surely you can find a local version for your AC supply.

If you need a DC supply version they have food delivery bags like this: https://www.amazon.com/dp/B0CKF9HQ6...industrial&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw

Just make sure the heated bag does not get too hot.

A great way to track battery temp is to apply color changing labels like these: https://www.mcmaster.com/59485K23/

We had to warm up 42 6S packs in our hydro when the temperature was around 50 degrees F early in the morning. We used hair dryers. For model boating I have a cooler/heater to store the batteries. In the past I could plug it into the car to heat the batteries on the way to the race.

Mark Scott from Cinci club gave me a class on warming up lipos prior to racing. I’ll be getting me a heating pad for next year.

Is it OK to store LiPo's in a cool place, say 10 deg C?

RaceMechaniX · Wednesday at 4:15 PM

That's a little cold. Ideally it is room temp. however, if the only safe place is 10DegC than better that then in the house.
