{"product_id":"the-cell-stack-21v-lithium-ion-battery-pack","title":"The Cell Stack | 21V Lithium-Ion Battery Pack for Makita Tools","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003e\u003cstrong\u003eRundown Is A Tool Problem, Not A Technique Problem.\u003c\/strong\u003e A drill that dies halfway through a deck job is not underpowered; it is under-supplied. This pack is built for the Makita 21 volt platform and stacks ten or fifteen lithium cells inside a single housing, which is where the runtime actually comes from. ONEVAN rates the increase at a hundred percent over a standard pack, and the arithmetic behind that claim is simply cell count.\u003c\/p\u003e\n\u003cp\u003eTwo capacities are offered. The 15000 mAh pack carries ten cells and the 22500 mAh pack carries fifteen, both at 18 to 21 volts and both CE marked. Cell count is the specification to buy against rather than the printed number: more cells mean more parallel capacity, so the tool holds its torque longer into a cut instead of tapering as the voltage sags. It is the difference between a battery that finishes the job and one that teaches you to keep a spare in the van.\u003c\/p\u003e\n\u003cp\u003eOrdering is structured around what you already own. The battery alone option is for buyers with an existing charger; the single-battery set adds one EU plug charger; the two-battery set pairs two cells with one charger, which is the configuration for people running two tools or working away from power. The larger fifteen-cell packs are available in the same three shapes, and each option lists the exact contents so nothing has to be assumed.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eBuy capacity once.

A fifteen-cell pack is the one that gets an installer through a run of decking or a staircase of fixings without a mid-afternoon charge, and two packs with one charger is the setup that keeps a second tool working while the first charges. Homeowners who already own a Makita-platform drill and a charger buy the battery alone and double their working time for less than the cost of a new tool body. Farm and estate work suits the two-battery set, because a remote job does not always have mains power within reach for a recharge. And anyone who has been carrying two tired packs around for a year will notice the difference the cell count makes in the first ten minutes of use.\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eee;\"\u003e\u003cdiv class=\"product-promise\" style=\"background: #fafafa; padding: 18px 20px; border-left: 3px solid #1a1a2e;\"\u003e\n\u003ch3 style=\"margin-top: 0;\"\u003eThe EastSupplier Promise\u003c\/h3\u003e\n\u003cp\u003eEvery unit is inspected before it leaves the warehouse.
