Frequently Asked Questions

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 to 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. Maximum power output depends on the battery’s discharge current rating and BMS limits.

How does this battery compare to lead-acid batteries?

The VTL12-200 weighs 22 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 VTL12-200 in series to create a 48V 200Ah battery bank, or connect up to four in parallel to create a 12V 800Ah bank. Always use batteries of the same model and state of charge, and make sure connections follow safe wiring practices and the battery’s built-in management system (BMS) limits to protect your batteries.

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 use this battery in cold weather?

The VTL12-200 can discharge at temperatures from -20°C to 60°C, but charging must take place between 0°C and 45°C.

For applications requiring charging below freezing, see the 12V 200Ah CW Lithium Battery, which supports charging from -30°C to 45°C.
