The LiTime 12V 100Ah Bluetooth Group 27 is a LiFePO4 deep-cycle battery built to drop into Group 27 compartments in RVs, boats and kayaks. It delivers 1200Wh of usable energy and up to 1200W output, with a 100A continuous and 500A surge BMS, Bluetooth 5.0 monitoring through the LiTime app, IP65 sealing and low-temperature cut-off. It is far lighter than a comparable lead-acid battery and rated for 4000+ cycles at 100% depth of discharge. Owners report long trolling-motor runtime and useful app data; the main trade-offs are the premium over basic lithium packs and the app dependence for detailed status.
