The RX1000 pulls consistent current to sustain temperatures up to 550°C, so the battery's ability to hold voltage under thermal load matters. Capacity is 2000mAh (36Wh) — a lighter-weight option within the P4A form factor.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRX1000 and BGX500 compatibility:\u003c\/strong\u003e Both models run the same 18V rail and P4A connector through the Power for All Alliance platform, so one battery cell configuration covers both.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage under sustained draw and tripped the low-voltage cutoff cleanly without hard shutdown artifacts.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst use on a hot air gun:\u003c\/strong\u003e Run one full charge cycle before the first high-temperature session — Li-ion cells perform more consistently once the BMS has completed an initial calibration pass.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy thermal load affects battery behaviour in the RX1000\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RX1000 draws harder current when maintaining upper temperature ranges — particularly near 500°C and above. A battery with a weak BMS will sag voltage under that load, causing the gun's LCD to show erratic readings or triggering early shutdown. This pack's protection circuit is rated for the sustained draw profile the RX1000 generates during continuous use.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGun powers on but cuts out mid-task — what's happening\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the RX1000 shuts off during a heat shrink or pipe-thaw job, the most common cause is the BMS detecting a voltage drop below its cutoff threshold under load. This happens when a battery is deeply discharged or stored flat for an extended period. Charge the pack fully before use and avoid storing it below 30% charge — that preserves cell capacity and keeps the BMS from tripping prematurely during high-draw cycles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175814398042,"sku":"BWCS-GRM180PW-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175814430810,"sku":"BWCS-GRM180PW-2","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175814463578,"sku":"BWCS-GRM180PW-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRM180PW-1.webp?v=1775236275","url":"https:\/\/batteryweb.com\/products\/rapid-rx1000-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
