Lithium Battery 12V 310Ah Olalitio OLA-12-310-MH Under-Seat Heating Bluetooth

Product description

The Olalitio OLA-12-310-MH 12V 310Ah Lithium Battery Under-Seat Heating Bluetooth is designed for mobile and off-grid installations operating in cold climates and requiring high autonomy at 12 V. Its under-seat design (slim format) allows use of limited spaces in campers and boats without sacrificing energy: it delivers 3,584 Wh with a nominal voltage of 12.8 V, a full BMS, and Bluetooth 4.0 for monitoring from your mobile device. It incorporates heating films that preheat the pack before charging when ambient temperature is low, protecting the cells and extending service life. With 200 A continuous discharge, peaks up to 640 A (200–500 ms), and a IP62 metal case, it is a robust, safe battery ready to operate in demanding conditions.

Main features

• High energy at 12 V: 3,584 Wh (nominal capacity 280 Ah; system at 12.8 V) with operating range 10–14.6 V.
• Sustained power: 200 A continuous discharge and up to 640 A peak for transient demands.
• Integrated heating: automatic preheating of the pack to enable safe charging in cold conditions.
• Longevity: >4,500 cycles at 90% DoD with excellent stability under continuous loads.
• Efficient charging: CCCV/IU profile at 14.6 V; 90 A recommended (max. 155 A).
• Under-seat format: 355 × 330 × 190 mm and 30 kg for compact installations in mobile applications.

Advantages or benefits

• Performs in winter: internal heating prevents damage from charging at low temperatures and keeps the battery available when you need it most.
• More autonomy with less space: replaces bulky lead-acid banks, reduces weight, and frees up usable volume in vehicles and boats.
• Smart management via Bluetooth: check voltage, current, estimated SOC, and BMS events in seconds to prevent deep discharges.
• Active safety: BMS protections against overcharge, overdischarge, overtemperature, and short circuit.
• Competitive cost per kWh: its long service life and charge/discharge efficiency reduce TCO compared to lead-acid.

Purpose or applications

Designed for camper vans and caravans (fridge, water pumps, lighting, 12 V outlets and inverter to 230 V), marine (onboard services and electronics), and 12 V solar power in shelters, cabins, telecommunications, or backup systems. The under-seat format and its IP62 protection enable clean installations resistant to vibrations, dust, and splashes, especially in mountain areas or extreme cold climates.

Technical specifications

Compatibilities

Compatible with 12 V MPPT/PWM solar charge controllers, 230 V chargers with lithium profile (14.6 V), and 12 V inverters. For expansions, respect the limit of up to 4S4P; use identical units (same brand/model and state of charge), balance them before connecting, and protect each branch with suitable fuses and disconnectors.

The OlaLitio OLA-12-310-MH 12V 310Ah Lithium Battery Under-Seat Heating Bluetooth combines a slim format, heating for cold climates, 200 A continuous current, and intelligent monitoring, providing a professional, durable, and safe solution for campers, boats, and 12 V solar projects.
