The 12V 100Ah Bluetooth LiFePO4 Battery is a 1,280 watt-hour Group 31 block with a Bluetooth BMS that reports to a phone app, on M8 terminals, rated IP65. It suits an RV or a boat where the owner wants to read the bank without a separate shunt gauge.
What The App Shows
Reading the bank from a phone
The Bluetooth BMS reports state of charge as a percentage, pack voltage, the current going in or out, cell temperature, and the cycle count. On a remote rig the owner opens the app and reads the bank from the phone. A weak cell or an over-temperature shows on the screen before it becomes a fault.
Against A Shunt
Two views of the same bank
A shunt meter counts amp-hours in and out at the wiring. The Bluetooth BMS reads the cells themselves: their voltage spread, their temperature, their balance. The two views complement each other. The BMS catches a cell drifting out of line that a coulomb-counting shunt cannot see.
Use
A bank you cannot reach
The battery fills any RV, marine or off-grid house role a 100Ah block does, with the monitoring added for a bank the owner cannot easily get to. The same 100 amp-hours and 4,000-to-8,000-cycle life sit behind the app.

Charging
A 14.6-volt lithium charger, an LFP solar controller or a DC-DC unit refills the pack, and the app shows the fill in place of a separate gauge.
