FAQs
Can WattCycle 12V 100Ah LiFePO4 batteries be used in extreme temperatures?
The recommended operating temperatures for WattCycle 12V 100Ah LiFePO4 batteries are:
- Charging: 0°C – 65°C
- Discharging: -20°C – 70°C
- Storage: 0°C – 60°C
The built-in Battery Management System (BMS) provides high- and low-temperature protection, ensuring safe operation. For example:
- Low-Temperature Protection: Automatically halts charging if the temperature drops below -20°C to prevent damage.
- High-Temperature Protection: Stops charging/discharging if temperatures exceed 65°C (charging) or 70°C (discharging).
Key Notes:
- Performance in Extreme Conditions: While the battery can operate in these ranges, optimal performance is achieved within 20°C – 25°C.
- Avoid Prolonged Exposure: Extended use outside the recommended ranges may reduce lifespan or efficiency.
- Storage: Keep the battery in a dry, temperature-controlled environment when not in use.
Safety First!
The BMS ensures safe usage, but always monitor battery conditions in extreme environments.
Can I connect 12V 100Ah LiFePO4 battery with a 12V 100Ah Mini battery?
Not recommended. WattCycle requires four rules for safely connecting batteries in series or parallel:
- Same brand
- Same voltage
- Same current (capacity)
- Purchased within 6 months
Why Mixing Different Batteries Is Risky:
- Imbalanced Performance: The 12V 100Ah LiFePO4 battery and mini battery likely differ in capacity, internal resistance, or age, leading to uneven charging/discharging.
- Reduced Efficiency: One battery may drain faster, forcing the other to overwork.
- Safety Risks: Mismatched batteries can overheat, degrade prematurely, or even fail.
Recommendation:
- Use identical batteries (same brand, voltage, capacity, and age) for safe and stable operation.
- If you need more capacity or voltage, stick to one battery type (e.g., If you need a 24V 100Ah battery system, then it is recommended to purchase a 24V 100Ah battery instead of 2 x 12V 100Ah LiFePO4 batteries).
What is the difference between a 12V 100Ah LiFePO4 battery and a 12V 100Ah Mini battery?
