Photonic Universe 20A 24V 7‑Stage Mains Battery Charger | 4Boats

Reliable 20 A 24 V mains battery charger with intelligent 7‑stage charging for safe, unattended charging of 24 V lead‑acid battery banks from 190–265 V AC.

• Compatible with Lead‑Acid batteries, including AGM, Gel and Wet cell batteries.
• Safe unattended charging: inbuilt protection against DC short circuit, overheating and overcharging; smooth, peak‑free charging voltage.
• Continued charging during battery use: maintains charge while energy is drawn and will hold batteries at full capacity.
• Boost‑charging feature: preliminary stage to improve battery condition and recover lost capacity, helping to extend battery life and prevent premature failure.
• Dead battery recovery: desulphation stage breaks down sulphation in batteries left flat, aiding recovery to full charge.
• Automatic temperature control: inbuilt fan engages automatically when high internal temperature or charging current is detected to maintain optimal operation.
• LCD display and LEDs: shows charging voltage, charging current and current charging stage; LEDs indicate battery type.
• Power pack function: supplies direct 24 V power to a load (e.g. 24 V fridge) without a battery; isolated DC output for safety.
• Specifications: AC operating voltage 190–265 V (full capacity) / 50 Hz; DC output current 20 A; DC output voltage 24 V; suggested battery capacity 40–300 Ah; bulk/absorption charging voltage 28.4–29.6 V DC (depending on battery type); float charging voltage 26.4 V DC (depending on battery type); efficiency <88%; operating temperature 0°C–40°C (32–104°F); inbuilt fan; isolated DC output; dimensions 226 x 175 x 95 mm (8.9 x 6.9 x 3.7 in); weight 1.2 kg (2.65 lb); 1 year manufacturer warranty.

Can charge a single 24 V battery or several identical 24 V batteries connected in parallel (batteries must be same type, capacity and age). Suitable for permanent connection and unattended operation; follow manufacturer guidance for installation and ventilation.
