It replaces OEM part number BST200. The pack slots into the tool's battery bay and connects to the same BMS handshake circuit as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAGS 7.2 Li and PKP 7.2 Li compatibility:\u003c\/strong\u003e\n    Both tools share the same 7.4V cell configuration, connector pinout, and BMS communication protocol. A single BST200-format pack works across the full Prio series because Bosch standardised the voltage rail and latch geometry across these compact garden tools.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the AGS 7.2 Li platform. The BMS accepted charge without fault codes, held the 7.4V rail steady under blade load, and tripped overcurrent protection correctly on a simulated stall test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBlade load cycling on first use:\u003c\/strong\u003e\n    On the first two uses, run the grass shear on light trimming passes rather than dense or wet grass. This lets the BMS log the motor's normal inrush signature before it locks in overcurrent thresholds — prevents nuisance cutoffs when you push into thicker growth later.\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 AGS 7.2 Li motor-start inrush surge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe AGS 7.2 Li blade motor draws a short current spike every time it starts. On a new or recently stored pack, the BMS defaults to conservative overcurrent thresholds because it has no inrush history to reference. If that spike exceeds the threshold, the BMS trips and the tool stops instantly at trigger pull. Running two or three light-load cycles lets the BMS record the normal inrush envelope and raise the cutoff window accordingly. After that profiling, motor-start cutoffs on normal growth should stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the BST200 pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that sit unused for several months can drop below the charger's acceptance threshold — typically around 2.5V per cell. The Bosch charger reads this as a fault and refuses to begin the charge cycle. To recover the pack, place it in the charger and leave it connected for 10–15 minutes without removing it — some chargers apply a low-current trickle to bring cells back above the 2.5V floor before switching to normal charge mode. If the charger still shows a fault after 20 minutes, check cell voltage directly; anything below 2.0V per cell indicates the pack will not recover safely.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416071012442,"sku":"BWCS-BST200PW-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416071045210,"sku":"BWCS-BST200PW-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416071077978,"sku":"BWCS-BST200PW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST200PW-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/bosch-ags-72-li-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
