🌡️ Temperature Protection

🔌 Charging Profile

For best performance, use a lithium-compatible charger with the following settings:

• Bulk Charge: 14.2V – 14.6V
• Ideal Bulk Charge: 14.4V
• Absorption: 14.2V – 14.6V
• Ideal Absorption: 14.4V
• Float: 13.4V – 13.6V
• Ideal Float: 13.5V

🔄 Long Cycle Life

The automotive-grade cells used in this battery are designed to withstand 3000 cycles at 80% depth of discharge under heavy electric vehicle use.

That means daily cycling from full charge down to 20% state of charge would take approximately 8.2 years to reach 3000 cycles. In lighter applications such as caravan, RV, and storage systems, service life may be even longer.
