🔧 Installation & Use

✅ Mounting

• Upright installation only

• Ensure good ventilation and a dry, shaded area

• Avoid direct sunlight and temperature extremes

• Keep battery accessible for maintenance

🔌 Connection Options

• Series: Voltage increases, Ah remains same (e.g., 4× batteries = 48V 105Ah)

• Parallel: Voltage same, capacity increases (e.g., 4× batteries = 12V 420Ah)

• Series-Parallel: Combine both for scalable 24V/36V/48V systems

🔗 Busbar Preferred

• Use busbars for multi-battery setups to balance charge/discharge paths and reduce resistance
