This dual purpose battery supports both outboards and connected loads (including electric fishing reel, fish finder, instrument panel, light, etc.) simultaneously for cranking and deep cycles. It maintains more than 4,000 cycles under recommended conditions, compared to the typical automotive SLA's 500 cycles. LiTime lithium batteries offer long-lasting performance, making the price per use a fraction of traditional batteries.

The advanced Bluetooth5.0 offers:auto-connection, smart discharging control, real-time battery monitoring, battery system checking. Stay informed and in control, ensuring your adventures are powered smoothly and efficiently.

When charging a battery in cold conditions, the power supply first heats the battery heating pad inside the battery. When the battery is heated to 10℃/50℉, the heating automatically ends and charging begins. The automatic self-heating function, activated by the BMS when charging between -20°C to 5°C (4°F to 41°F), ensures charging and reliable power backup in cold weather. This feature offers reliable battery charging conditions by reaching the set temperature in 40-60 minutes from -10°C (14°F) and 60-80 minutes from -20°C (-4°F). This ensures reliable power for your marine needs, even in harsh conditions.
