Deal Details
Found this 2-pack of DeWalt's newer 4Ah XR Powerpack batteries (DCB2104-2) on sale.<br />These are the updated versions that use tabless cells instead of the standard 21700s found in the older DCB240s, so they run cooler and have less voltage sag under heavy loads. Solid upgrade if you need extra juice for high-draw 20V tools (circular saws, grinders, etc.) without the bulk of a 5Ah or 6Ah pack.<br />Comes with two 4Ah batteries with the standard 3-LED fuel gauge. Works with all regular 20V Max tools and chargers.

I think that tabless 21700 5s1p 4ah / 40A discharge cells command a premium over 18650 packs because they're light yet still powerful and high-capacity. The Ridgid version of this is $150 for a single one MSRP and rarely goes on sale; I'd buy two in a heartbeat if they offered two at $120.
