It fits the KX-RS 18 Li Solo, KX-AHS 1858 Li Solo, KX-AKS 1825 Li Solo, KX-ARM 3637 Li, and six additional models in the same voltage platform. Capacity is 2000mAh, delivering 36Wh of stored energy per charge cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-RS 18 Li Solo platform fit:\u003c\/strong\u003e\n    All listed models run the same 18V rail and share an identical battery interface — same connector pitch, same BMS communication protocol, same terminal orientation. Swapping between compatible tools in this range requires no adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack under a simulated motor-start inrush load. The BMS held the rail stable through the trigger-pull spike and did not trip overcurrent protection during repeated cold starts at rated voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor load break-in on first use:\u003c\/strong\u003e\n    Run the tool at half load for two cycles before full-torque applications. This allows the BMS to profile the motor's inrush current draw and set overcurrent thresholds accurately before you push maximum load through the pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on drill motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill under load, the motor draws a current spike several times higher than the steady running current. If the BMS has not yet calibrated its overcurrent threshold — common with a new or storage-rested pack — it can read that spike as a fault and cut the output rail instantly. The fix is to start the tool unloaded two or three times before applying torque. This lets the BMS log the inrush signature and adjust its trip point accordingly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that have sat unused for several months can drop below the charger's minimum acceptance voltage — typically around 2.5V per cell. When that happens, the charger sees a pack voltage below its wake threshold and either blinks an error or does nothing at all. To recover the pack, place it on the charger for 30 minutes and check for any status change — many chargers will trickle-charge below threshold and eventually accept the pack. If the charger shows no response at all after one hour, measure the pack voltage at the terminals; anything below 12V on an 18V pack signals cell damage rather than a recoverable deep discharge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416011931738,"sku":"BWCS-EHX184PW-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416011964506,"sku":"BWCS-EHX184PW-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416011997274,"sku":"BWCS-EHX184PW-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EHX184PW_1.webp?v=1779759462","url":"https:\/\/batteryweb.com\/products\/kraftixx-kx-rs-18-li-solo-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
