Banshee 4 V replacement cell

The Banshee 4 V 2000 mAh lithium-ion battery replaces Milwaukee part 48-11-2001. It powers every M4 cordless tool in the range. A two-year warranty backs the pack. Tradespeople and DIY users get a direct drop-in power source.

Fits M4 platform without adapters

The cell slides into existing M4 tools and chargers, so no new charging hardware is required. It frees the operator from hunting for discontinued original packs. The black housing matches the factory look. Builders who need a second voltage platform or a higher-capacity format will not be served by this pack.

Steady output during extended runs

Quality cells hold voltage through long drilling or driving sessions rather than sagging after a few bursts. Consistent current lets the tool maintain torque until the pack is empty. The two-year warranty reflects confidence in that sustained behaviour.

Questions about this item

How long will the 2000 mAh capacity last under continuous use?

Runtime depends on the specific M4 cordless tool and the load applied; the 2000 mAh rating indicates total charge capacity at 4 V.

Does the battery get hot or lose power during all-day operation?

Lithium-ion chemistry maintains steady voltage until near depletion; normal warm-up occurs under heavy load but the pack is designed for sustained use in M4 tools.

Which Milwaukee tools must I already own for this battery to fit?

It fits all Milwaukee M4 cordless tools that accept the 48-11-2001 form factor.
