Is 50Ah enough for a trolling motor?

For a small motor at low speed, yes, but runtime will be short. Most boaters running a trolling motor all day want 100Ah or more.

Can it replace a lead-acid battery directly?

Physically it fits most Group 24 and similar trays, but check that your charger has a lithium or LiFePO4 mode. Lead-acid chargers may not fully charge it.

Can I charge it in freezing weather?

No. Charging is rated for 32°F to 122°F. Below freezing, the BMS should block charging to protect the cells.

How long will it last?

LiTime rates it for more than 4,000 deep cycles, with a 10-year shelf life. Real-world life depends on depth of discharge and charging habits.

What comes in the box?

One 50Ah battery. M8 bolts for the terminals are typically included; a charger is not.

When is the price lowest?

The best new price seen is $179.54 at eBay as of November 5, 2026. Lithium battery prices tend to dip around holiday sales and boating-season clearance.
