Abyss Dual Purpose Lithium Marine Battery withBluethooth - A high capacity Group 49 Lithium-Iron-Phosphate battery engineered with the strongest 200A BMS rating of its class and designed with mid-sized center console boats power needs in mind. The 12V 240Ah has dual purpose capabilities and features making it ideal for starting outboard motors and supplying enough power for worry free overnight trips at sea. This battery will also accept charge from your engine’s alternator with no additional equipment necessary and is equipped with built-in Bluetooth connectivity, which allows the user to wirelessly monitor battery health, operation status and troubleshoot diagnostics. Dual purpose lithium battery is ideal for powering Seakeeper systems, A/C refrigeration, chill plates, and other high energy storage applications. Higher qualified Grade-A cylindrical cells UL1642, IEC62619, IEC62133 listed with Cycle life more than 3000 times and excellent consistency. Bluetooth Connectivity Monitor the battery status (charge, discharge, current, temperature, cycle life and so on) and change the data for different applications. Push Button Wake-Up/Reset Feature Located Conveniently on top of the battery case, this button allows for easy waking up or resetting of the battery, ensuring quick and effortless operation. Built-in Heating Uniform internal heating is an important feature of our cold-weather performance batteries, as many external heating blanket options currently available cannot sense the internal temperature of the cells and may not be completely effective at heating the battery throughout. System features proprietary technology that draws power from the charger itself, requiring no additional components. The entire process of heating and charging is completely seamless. Simply plug the battery into our lithium charger and the internal heating and monitoring system takes care of the rest. More stable and firm internal structure The cell holders within our battery protect and separate each cell to avoid any short circuit risks caused by intense vibration or impact. The separation and space created between each cell also improves the overall heat dissipation within the battery pack while charging and discharging.
