Is this battery actually 100Ah?

The listing says 100Ah, but the 8000mAh figure is likely a mislabeled spec. Budget LiFePO4 packs often test below their rating, so check capacity with a shunt or load test soon after it arrives.

How does it compare with LiTime or Chins?

It targets the same 12V 100Ah LiFePO4 niche at the low end. Those brands publish cell grades, BMS limits and warranties; this one gives you less to verify, so the risk sits with you.

Can I use it for a trolling motor or inverter?

A 100A continuous rating covers most 12V trolling motors and inverters up to about 1000W. Confirm the BMS actually allows 100A before pushing it hard.

Does it have low-temperature charging protection?

Not confirmed. Charging LiFePO4 below freezing damages it, so if you use it in cold climates, add your own temperature cutoff or keep it above 32°F.

What charger should I use?

A LiFePO4-specific charger or solar controller set to 14.4–14.6V absorption and 13.6V float. Avoid lead-acid desulfation modes.

What comes in the box?

Typically just the battery, sometimes with terminal bolts. Expect no charger, no monitor and no manual worth much, so plan for accessories separately.
