Charging settings and compatibility guidance

To get the best results from this solar battery, your charging equipment should be programmable for lithium chemistry. That includes inverter chargers, DC-to-DC chargers, converter chargers, and solar controllers.

Recommended charging parameters

• Bulk / absorption: 14.2V to 14.6V
• Absorption time: Two batteries in parallel connections require 30 minutes 200Ah
• Float: 13.4V to 13.8V
• Equalization: 14.4V / Disabled
• Temperature compensation: 0 / Disabled
• Charge rate: 50% of battery or battery bank capacity
• Battery charge temperature range: 32°F (0°C) to 131°F (55°C)
• Battery discharge temperature range: -4°F (-20°C) to 140°F (60°C)
• Cell charge temperature: 32°F (0°C) to 131°F (55°C)
• Cell discharge temperature: -4°F (-20°C) to 140°F (60°C)

Important: If your charger does not support multistage charging, confirm that the bulk and absorption voltages can still be set correctly and that unsupported features are disabled. Always verify compatibility with the charger manufacturer before installation.
