The Victron LiFePO4 12V 100Ah Smart is a lithium iron phosphate deep-cycle battery for off-grid, marine and vehicle power systems. It has integrated cell balancing, can be wired in parallel or series, and streams cell voltage and temperature to the VictronConnect Bluetooth app. Unlike drop-in lithium batteries with a built-in BMS, it needs a separate Victron BMS (VE.Bus, smallBMS, BMS 12/200, Smart BMS 12/200, Smart BMS CL 12/100 or Lynx Smart BMS) chosen to match the system. That makes it a fit for Victron-based builds rather than a simple swap for a lead-acid battery.

Owners of Victron off-grid and marine systems rate the battery for its stable voltage, long cycle life and the cell-level data in the app. The recurring complaint is the extra BMS requirement and the planning it forces.
This is a 12 V, 100 Ah Smart LiFePO4 (lithium iron phosphate) battery from Victron. It has integrated cell balancing. Batteries can be connected in parallel and in series.
A Bluetooth app lets you monitor cell voltage and temperature. The battery requires a compatible BMS (battery management system) to operate.
