Is 100Ah or 120Ah the real capacity?

The name says 100Ah but the specs list 120Ah. Ask the seller to confirm before buying, and check the label on arrival.

Can it run a trolling motor?

A 100A BMS suits most 12V trolling motors up to about 1,000W. Check your motor's max current draw against the 100A limit.

Does it work in cold weather?

The stated range is -20 to 60 °C, but no low-temperature charging cutoff is listed. Do not charge below freezing unless the BMS confirms protection.

Is $117 a good price?

It is the lowest of the three stores pricing it new as of November 5, 2026. That is well below branded 100Ah LiFePO4 batteries, which reflects the unknown brand.

What can I run with it?

About 1.2 kWh if it truly holds 100Ah, enough for a small fridge, lights and a fan overnight or a day of trolling.

Typically just the battery. Terminals and a charger are usually not included, so check the listing before ordering.

Our take on the KEPWORTH 12V 100Ah LiFePO4 Lithium Battery with 100A BMS

The KEPWORTH is a 12V lithium iron phosphate (LiFePO4) battery rated at 100Ah, with a 100A battery management system built in. It is aimed at solar storage, trolling motors, RVs and off-grid setups, and KEPWORTH claims more than 6,000 charge cycles. The listing specs show 120Ah capacity and 15 kg weight, so confirm the real figure before you buy. At $117 at eBay as of November 5, 2026, it is the lowest of the three stores that price it new, well under what branded 100Ah LiFePO4 batteries usually cost.
