LiFOS battery charging in sub zero temperatures

[Ian28]

Hi, apologies if this has already been asked but is it detrimental to a lithium battery to charge it via hook up in sub zero temperatures? We’re expecting down to -3 tonight and it’s on hook up just now.

Safety - LiFOS

LiFOS does not emit noxious gases therefore does not need to be housed in a specially vented chamber. LiFOS has a huge operating temperature range of -20 to +60 °C and it can be used in any orientation (e.g. on its side), although on its base will give the best performance.

"Note: Lifos can discharge in temperatures down to -20°C but cannot receive a charge at any temperature lower than 0°C. If Lifos is housed within a housing such as a caravan battery compartment or similar, it should be protected from freezing temperatures. If, however, Lifos is exposed to the elements it should be placed inside a battery box or similar with some level of insulation."

No you can’t charge below zero deg C without damaging the battery. Disconnect it. Remember it’s the battery temperature not the air temperature that counts so don’t re-connect in the morning just because the air temperature has risen. Check the battery temperature.
Temperature sensors are available for various batteries.

Cheers chaps. Will nip out & disconnect to be safe.
