Frequently Asked Questions

What makes the VTL12-200CW a cold-weather battery?

The VTL12-200CW supports charging at temperatures as low as -30°C (-22°F). The standard VTL12-200 requires a temperature of at least 0°C (32°F) for charging. This makes the CW model a suitable choice for applications requiring charging below freezing. Its discharging temperature range is -20°C to 60°C.

What is a LiFePO₄ lithium battery?

LiFePO₄ stands for Lithium Iron Phosphate. This battery chemistry offers long cycle life, stable performance and a lighter design than many comparable lead-acid batteries, making it suitable for compatible solar, RV, marine and backup power systems.

How does this 200Ah battery compare with 100Ah models?

At the same nominal voltage, a 200Ah battery provides twice the energy storage of a 100Ah battery. This can provide approximately twice the runtime under comparable conditions. The VTL12-200CW also includes Bluetooth monitoring and cold-weather charging capability.

How does this battery compare with lead-acid batteries?

The VTL12-200CW weighs 21.8 kg and offers a rated cycle life of 4,000+ cycles at 50% depth of discharge. LiFePO₄ batteries generally maintain a steadier voltage during discharge than lead-acid batteries. Actual runtime and service life depend on the load, charging settings, temperature and depth of discharge.

Can I connect multiple batteries together?

You can connect up to four VTL12-200CW batteries in series to create a nominal 48V 200Ah battery bank, or up to four in parallel to create a nominal 12V 800Ah battery bank. Use batteries of the same model and capacity, with matching states of charge before connection. Follow the manufacturer’s connection instructions and BMS limits, and use wiring, fuses and charging equipment suitable for the battery bank.

Do I need a special charger?

Use a charger with a LiFePO₄ charging profile that meets the battery manufacturer’s voltage and current specifications. If using a multi-chemistry charger, select its LiFePO₄ setting and disable lead-acid equalization or desulfation modes.

Can I recharge this battery below freezing?

Yes. The VTL12-200CW supports charging from -30°C to 45°C (-22°F to 113°F). Follow the manufacturer’s charging instructions and current limits throughout this temperature range.
