The V20 Lithium Ion Battery provides up to 3x the capacity versus the standard of a 20V MAX lithium battery. It is built to charge compatible CRAFTSMAN V20 lithium-ion batteries for shop, home, and jobsite use.
What does the CMCB204-CKVA include and what makes it a starter kit?
The kit ships with one 2Ah V20 battery, one 4Ah V20 battery, and a charger. The two different capacity packs let you match battery size to the task — 2Ah for lighter tools and faster recharge, 4Ah for outdoor equipment and sustained sessions.
Why buy a mixed 2Ah and 4Ah kit instead of two packs at the same capacity?
A mixed kit gives you a low-weight option for drills, drivers, and small tools (2Ah), and a high-runtime option for outdoor power equipment and longer tasks (4Ah). This covers more use cases from a single purchase than two identical packs would.
Is the CMCB204-CKVA the right starter kit for a new V20 owner?
Yes. The mixed pack gives a new V20 user immediate range: light duty on the 2Ah and sustained outdoor work on the 4Ah. If you expect to use V20 primarily for indoor power tools, the CMCB202-2CK with two 2Ah packs is a lower-cost alternative.
How does the CMCB204-CKVA compare with the single 4Ah kit CMCB204-CK?
The CMCB204-CK gives you one 4Ah battery and a charger — the better choice if you already own a charger and just need one high-capacity pack. The CKVA adds a 2Ah battery and is the better complete starter purchase if you are buying both a charger and your first pair of V20 packs.
Can the charger in the CMCB204-CKVA be used with other V20 batteries bought separately?
Yes. The included single-port V20 charger works with any V20 battery — any capacity from 1.5Ah to 9Ah — that you add to your lineup later. It is the standard CRAFTSMAN V20 charger, compatible across the full platform.
