Warnings / Reminders

• Check the orientation of positive and negative terminals before wiring.
• Connect terminals with proper insulation to prevent short circuits.
• When not in use for long periods, store in a cool, dry place (<35°C) with 30–50% SOC and recharge every 3 months.
• Avoid exposure to direct sunlight or heat sources.
• Do not wear metal jewelry when handling the battery unit.
• Operate within the specified temperature range (-20 to 60°C).

For EU orders, VAT handling is managed to simplify your purchase, and delivery timelines typically involve longer transit times due to the nature of high-power batteries.
