It matches the OEM voltage rail, connector pinout, and BMS communication protocol these units expect. Capacity figure is from the product specification — not estimated from web sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS7000 and S7200 pack compatibility:\u003c\/strong\u003e\n    Both models run the same 7.4V power architecture and share the B205D001 \/ B205D002 \/ HYLB-1371 part numbers across production runs. The connector and BMS handshake are identical across the S7000 and S7200 chassis, so one replacement pack covers both instruments.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through full charge and discharge cycles, monitored BMS cutoff thresholds, and verified the cell voltage stays within the window the S7000 firmware expects during sensor initialisation and sustained logging loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the S7000 and S7200:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before heading into the field. The S7000 and S7200 map battery state during calibration — skip this step and the instrument will flag premature low-battery warnings during the first measurement session even with a full charge.\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 S7000 probe or sensor initialisation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the S7000 powers up a connected probe or sensor module, there is a short current spike as the module initialises. If the battery's BMS has a tight overcurrent threshold — common in aged or deeply discharged packs — it interprets this spike as a fault and cuts output. The instrument appears to power on, then immediately shuts off or throws an error before completing startup. This replacement pack is rated to handle the initialisation draw without tripping the BMS cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eS7000 readings drifting or logging session resetting mid-survey\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor operation draws a consistent current load over extended sessions. If the battery pack's internal resistance has climbed — through cell age or prior deep discharge — voltage droops enough under that load to cause the instrument's processor to reset or corrupt the active logging session. This is not a firmware fault; it is a voltage dropout event. Check the battery terminal voltage under load — if it drops below 6.8V during active measurement, the pack is no longer fit for field use and needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43303968997466,"sku":"BWCS-DRS700SL-1","price":101.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43303969030234,"sku":"BWCS-DRS700SL-2","price":119.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43303969063002,"sku":"BWCS-DRS700SL-3","price":133.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRS700SL_1.webp?v=1777520716","url":"https:\/\/batteryweb.com\/products\/deviser-s7000-replacement-battery-74v-13000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
