The Greenoe 12V 100Ah is a Group 31 lithium iron phosphate battery with a built-in 100A battery management system. It replaces a comparable lead-acid battery at roughly half the weight while delivering usable capacity down to near-full discharge, and it can be wired in series and parallel up to 48V 400Ah for larger banks. The BMS blocks charging below freezing and discharging below -4°F, so it suits RVs, solar, trolling motors and off-grid builds. Against premium brands it is a budget option; its 3.8-star average suggests buyers like the capacity and price but some units have arrived with weak cells or BMS faults.

Owners who got good units praise the capacity, light weight and easy drop-in replacement for lead-acid. A notable share of the 120 ratings report problems: batteries that arrived at low voltage, cells that fell out of balance, or a BMS that shut off early.
The Greenoe 12V 100Ah battery uses LiFePO4 (lithium iron phosphate) chemistry in a Group 31 size. It is built with Grade A+ cells and is UL certified. The chemistry is non-toxic and stable, which removes acid risks and thermal runaway and allows flexible installation.
A built-in 100A smart BMS protects the battery against extreme temperatures, overloads and short circuits. Discharge cuts off at -4°F and charging cuts off at 32°F. The battery charges in about 5 hours at 14.6V and 20A.
Batteries can be connected to expand the system up to 48V 400Ah (4S4P), which stores 20.48kWh. It is used in RVs, solar systems, trolling motors and off-grid setups, and it can replace a lead-acid battery.
