The lithium-ion battery pack features superior pack construction， electronics， and performance providing users more work per charge and more work over pack life than any battery on the market.

Each battery pack is durably built for heavy-duty use， runs cooler， and performs in climates below 0 degree F/minus 18 degree C.
