ECO-WORTHY 12 V 100 Ah LiFePO4 with Bluetooth and low-temperature cut-off review

A 12 V 100 Ah LiFePO4 battery with a 100 A BMS, Bluetooth monitoring, and published low-temperature thresholds for both charging and discharging.

The bottom line The most complete cold specification in this family, published as three separate thresholds rather than one vague reassurance. Against that, no terminal type — the single fitting detail every other battery here publishes.

A 100 Ah LiFePO4 pack whose sheet is built around the thing most listings avoid: what happens in winter.

Three thresholds, not one

Charging stops at −7 °C. Discharging stops below −20 °C. Charging resumes at 0 °C or above. Three numbers, each describing a different behaviour, and together they describe how the pack will act on a January morning better than any general statement about the chemistry could.

That last figure matters most: a pack that stops charging at −7 °C does not start again at −6 °C. It waits for zero.

Current, in amps

100 A continuous in both directions, published plainly. That places the battery against an inverter without any conversion, and it is the figure two other batteries in this family omit entirely.

Expansion

Up to four in series or parallel, for 25.6 V 400 Ah or 51.2 V 200 Ah, and a stated 10.24 kWh maximum. The arrangements are named, which makes the ceiling checkable.

A cycle count with no depth behind it

No terminal type. Every other LiFePO4 here publishes M8 or similar; this listing gives dimensions and weight and stops. Anyone replacing an existing battery will need that answer before ordering.

What it gets right, and what it leaves out

Strengths

  • Three separate cold thresholds published — charge stop, charge resume and discharge stop
  • A continuous current is published in amps for both directions
  • Bluetooth monitoring with a stated range and nine app languages

Compromises

  • No terminal type at all, which is the one fitting detail this listing omits
  • The 15000-cycle figure carries neither of its two qualifiers
  • No peak discharge current, only the continuous figure

Questions owners ask about this one

Why are there three temperature numbers?

Because charging and discharging behave differently in the cold, and recovery has its own threshold. Charging stops at −7 °C because cold charging damages lithium cells permanently; discharge continues to −20 °C because taking current out does not. Charging resumes only at 0 °C or above, not at −7 °C.

How does this compare with the FEENCE threshold?

FEENCE stops charging at 0 °C and resumes at 5 °C; this pack stops at −7 °C and resumes at 0 °C. Same chemistry, different thresholds — which is why the figure belongs to the pack and its management system rather than to LiFePO4 in general.
