**1. Know the temperature limit**

- Lithium batteries should not be charged below 32°F (0°C).
- Charging them while frozen can permanently damage them.

 

**2. Understand what your battery will do**

- Your battery has a Battery Management System (BMS).
- When it’s too cold, the BMS will automatically stop charging to protect the battery.

 

**3. Recognize the signs**

- Your solar panels may still produce power.
- But your battery won’t accept the charge.
- Your charge controller may show energy with “nowhere to go.”

 

**4. Keep using power normally**

- You can still run devices like: 
    - Lights
    - Fridge
    - Electronics
- Discharging (using power) is fine- even in the cold.

 

**5. Expect battery drain**

- Since charging is blocked, your battery will slowly drain as you use it.
- It won’t recharge until it warms up.

**6. Prevent the problem (best solutions)**

- Option A: Keep batteries warm
  
    - Store batteries in a heated space if possible.
    - Some RVs/trailers route furnace heat to the battery area.
- Option B: Use battery heaters
  
    - Install battery heating pads or blankets.
    - These use a small amount of power to keep batteries warm enough to charge.
- Option C: Plan ahead
  
    - On freezing days, assume solar charging may not work until temperatures rise.
    - Budget your power usage accordingly.

 

**7. Know your alternatives**

- AGM batteries can charge in cold weather without this restriction.
- Lithium batteries require more planning in freezing conditions.

**Bottom line**

- Keep lithium batteries warm OR
- Accept that charging will stop when it’s freezing
