Why AIMS Power?  Transparency and accuracy are at the core of our product specifications. When it comes to lithium batteries, we ensure our stated amp hour capacity and weight accurately reflect the high-quality materials and components used in our products. While lithium batteries are indeed lighter than traditional battery technologies, there is a minimum weight threshold required to achieve full amp hour capacity. We encourage customers to verify product specifications carefully, as discrepancies in weight may indicate a compromise in performance or capacity.

Maintenance Tips    

• Install in a dry, ventilated location away from direct heat and moisture to protect the internal BMS and heater system.
• Periodically check terminal tightness (M8 studs) and keep connections clean to ensure stable high-current performance.
• Monitor via Bluetooth app (AIMSBATC) to track state of charge, temperature, and cycle health for early issue detection.
• Ensure proper charging range (14.2–14.6V recommended for 12V LiFePO4 systems) using a compatible charger or inverter setting.
• Avoid deep discharge—let the BMS handle low-voltage cutoff instead of fully draining the battery.
• In cold weather, allow the built-in heater to warm the cells before charging for safe operation and longer lifespan.
• Do not exceed recommended continuous charge/discharge limits (~100A) to prevent stress on the BMS.
• Store at ~40–60% charge if unused for long periods to preserve cycle life and capacity stability.
