Battery Spot Welder 1.5ft LCD Screen 11000mAh - Portable Spot Welder

In this review of the Battery Spot Welder from AWithZ, the reviewer finds it best suited for hobbyists and DIYers who build or repair battery packs and small metal parts. The single biggest reason to buy is its combination of a high capacity 11000mAh internal battery and an easy to read 1.5' LCD screen, which lets users perform multiple spot welds away from an outlet and monitor gear, temperature, and remaining charge clearly.

Key Features

• High capacity battery: The built-in 11000mAh cell lets users charge once and perform multiple welds, and it recharges in about 3.5 hours so projects are not delayed long.
• 99 adjustable gears: A wide power range allows fine tuning for thin cell tabs up to thicker nickel strips so the tool can handle 18650 packs and slightly heavier materials.
• Large LCD display: The 1.5' screen shows remaining battery, temperature, gear, trigger time, and continuous spot-weld count for clearer control during work.
• Double continuous weld: The upgraded function supports two continuous spot welds to better join thicker materials without manual repetition.
• Complete starter pack: Packaging includes nickel plated strip, Type-C cable, spot welding pens, and basic accessories so users only need their welding battery to begin.

Who It's For

This spot welder is ideal for small-scale battery builders, makers, and repairers who work with 18650 cells, e-bike packs, or handheld power tool batteries and need a portable unit with adjustable power and clear readouts. The LCD and gear options make it approachable for those who want repeatable settings for different tab thicknesses and materials.

Those who need industrial throughput or pneumatic arms for high-volume production should look elsewhere; this unit is designed for hobby, workshop, and repair use rather than continuous factory output, though it does improve capability with two continuous welds.

Pros & Cons

Pros

• Compact and portable with a large 11000mAh battery that supports off-grid welding jobs.
• Accurate control via 99 adjustable gears and clear LCD feedback, which users praised for ease of use.
• Includes essential accessories in the box so beginners can start building battery packs quickly.
• Upgraded continuous-weld function expands the range of material thicknesses it can handle.

Cons

• Not intended for heavy industrial use; users with high-volume welding needs should choose a larger bench system.
• Some users may need time to learn the correct gear settings for particular tab thicknesses despite the wide range.
