Battery and Charging Compatibility
This is a 12.8V nominal LiFePO4 battery for 12V systems; it is not a battery charger. It is listed for kayaks, fish finders, and small 12V systems, so chargers and connected equipment must be suitable for a 12V LiFePO4 battery.
Bluetooth Smart App Control is listed for monitoring battery information. Confirm that the intended charger uses the battery manufacturer’s required LiFePO4 settings and that connected equipment does not exceed the listed 50A continuous or 100A surge discharge limits.
Installation and System Considerations
The battery uses M8 stainless-steel terminals, measures 7.7 in. by 6.5 in. by 6.7 in., and weighs 14.3 lbs. It has an IP67 waterproof enclosure and an internal heat strip. Installation should follow the battery manual and the electrical requirements applicable to the vessel or 12V electrical system.
Warranty and Support
Warranty information is not included in the listed product data. Review the manufacturer documentation for product details, setup, and warranty coverage.
Before Ordering the Epoch 12V 50Ah Marine Lithium Battery
Before ordering, confirm that your system uses a compatible 12V-class, 12.8V nominal LiFePO4 battery. Review the 50Ah capacity, 640 Wh energy rating, 50A continuous and 100A surge discharge limits, dimensions, 14.3 lb weight, IP67 rating, internal heating, and Bluetooth monitoring needs. You should confirm compatibility with your charger and vessel or small-system electrical equipment before purchase.
