It slots into the same battery bay and runs on the same 18V rail as the original pack. Capacity is 3000mAh (54Wh) — pulled directly from the product spec, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP318 \/ P326 \/ P327 \/ P328 platform fit:\u003c\/strong\u003e\n    These models share the same 18V battery bay, connector pinout, and BMS handshake protocol — which is why one cell pack covers the full range. Swapping across models in this series does not require re-pairing or charger changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the P318 platform. The BMS logged cell balance correctly on the first cycle and held the 18V rail steady through repeated trigger pulls without a false overcurrent trip.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in protocol for strapping tool use:\u003c\/strong\u003e\n    On first use, run the tool at partial tension cycles before applying maximum strap tension — this lets the BMS profile the motor inrush current draw and set overcurrent thresholds before you hit peak load. Skipping this step can cause nuisance cutoffs on the first full-tension job.\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 motor-start inrush during strap tensioning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eStrapping tools pull a sharp current spike the moment the motor engages — higher than steady-state draw. If the BMS has not yet profiled the motor's inrush signature, it can read that spike as an overcurrent fault and cut the pack. This is not a cell failure. The BMS is tripping on a threshold it set without enough data. Running two or three partial-load cycles recalibrates that threshold, and the cutoffs stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red on a new pack that has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If a pack sits long enough, cell voltage can drop below the charger's acceptance threshold — typically around 2.5V per cell — and the charger refuses to enter CC\/CV charge mode, flashing a fault instead. This is recoverable. Most Fromm-compatible chargers have a trickle or recovery mode: hold the charge button for five seconds or disconnect and reconnect the pack three times to force the charger into recovery mode. Once cell voltage climbs above 3.0V per cell, normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416058232922,"sku":"BWCS-MKM180PW-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416058265690,"sku":"BWCS-MKM180PW-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416058298458,"sku":"BWCS-MKM180PW-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKM180PW-1.webp?v=1779759860","url":"https:\/\/batteryweb.com\/products\/fromm-p318-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
