Why charging lithium batteries below 32 F (0 C) causes anode lithium plating
During discharging, lithium ions leave the graphite anode and move to the cathode, a reaction that remains safe down to -4 F (-20 C) with only a temporary drop in usable capacity due to higher internal electrolyte resistance. During charging, however, lithium ions must intercalate (slip between) the microscopic layers of the graphite anode.
Below 32 F (0 C), lithium-ion diffusion into graphite slows down sharply. If charging current is forced into a freezing cell, lithium ions pile up on the anode surface as metallic lithium dendrites ('lithium plating'). Those metallic spikes permanently reduce capacity and can pierce the separator, creating an internal short circuit. Every reputable power station uses thermistor sensors on the cell pack to block charging below 32 F.

Our specification fetch logs extract stated operating temperature limits directly from official manufacturer specification pages and user manuals. Standard LiFePO4 models across Anker SOLIX, Goal Zero, VTOMAN, Zendure, and Jackery state a minimum charging temperature of 32 F (0 C) with upper limits between 104 F and 131 F (40 C to 55 C), and a discharging temperature floor of -4 F (-20 C) or 14 F (-10 C).
Cold-weather sodium-ion (Na-ion) models such as the Bluetti Pioneer Na (900 Wh) are rated on the manufacturer's specification page to charge down to 5 F (-15 C) and discharge down to -13 F (-25 C) without lithium plating risk.

First, keep the power station inside your heated living space or vehicle cabin while running an extension cord outdoors to your solar panels or generator; only the battery cells need to stay above 32 F, while solar panels actually operate at higher voltage in freezing outdoor air.
Second, if a power station has been sitting in a cold car trunk or unheated shed below 32 F, bring it indoors or power a small 100 W to 200 W AC load for 20 to 30 minutes first; discharging generates gentle internal warmth across the cells, raising pack temperature above the 32 F BMS charging threshold.

Can solar panels stay outside in below-freezing weather while the power station is inside?
Yes. Photovoltaic solar panels work well in sub-freezing weather. Warning: cold temperatures increase panel open-circuit voltage (Voc) by roughly 10% to 15% below freezing, so leave at least a 15% safety margin below your power station's maximum solar input voltage limit.
Will storing a LiFePO4 power station in an unheated garage below freezing ruin it?
Storing or discharging a LiFePO4 station down to -4 F (-20 C) at 50% to 80% state of charge does not damage the cells, provided you never attempt to charge it until internal cell temperature is back above 32 F (0 C).
Which battery chemistry charges natively below freezing without heaters?
Sodium-ion (Na-ion) portable power stations can charge in sub-freezing temperatures (down to 5 F / -15 C on the Bluetti Pioneer Na) without lithium plating risk.
