Total Lithium-Ion battery pack 4.0Ah 20V TFBLI2002

Total TFBLI2002 (often updated as TFBLI20021 in newer tool kits) is a heavy-duty, high-capacity 20V Max 4.0Ah Lithium-Ion battery pack. It is the powerhouse of Total’s P20S (20V Max Share) tool ecosystem.

Unlike the slim 2.0Ah battery pack, this 4.0Ah model uses a dual-row cell configuration. This doubles the available runtime and—more importantly—doubles the amount of current (amps) the battery can dump into a tool simultaneously.
