It fits field engineers and technicians who carry the S700 for signal strength surveys, frequency response checks, and transmission quality testing. Capacity figures come from the product data sheet, not estimations.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS700 platform compatibility:\u003c\/strong\u003e\n    The S700 uses a fixed 7.4V two-cell Li-ion architecture with a proprietary BMS handshake that verifies pack chemistry and cell configuration at power-up. This replacement uses the same cell layout and communicates through the same connector pinout, so the instrument completes its startup sequence without throwing a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the S700's power management circuit and monitored BMS response during cold-boot initialisation and sustained RF scanning loads. The BMS held voltage above the instrument's low-battery cutoff threshold throughout the sustained draw cycles, and no overcurrent trip was recorded during probe-power events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePre-deployment calibration step:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the S700's instrument menu before heading out to site. The S700 maps battery state during calibration, and skipping this step causes the low-battery warning to trigger early on the first measurement session, cutting a survey short at a stable charge level.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during RF probe or antenna module initialisation on the S700\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the S700 powers up its active antenna input or switches probe modes, it draws a short current spike that can trip a marginal or aged BMS before any measurement starts. A new pack with full cell capacity handles this spike without hitting the overcurrent threshold. An old or partially degraded pack may have elevated internal resistance, making that brief spike large enough to trigger a protective cutoff. If the unit shuts off at the exact moment the probe activates, the pack's cell health — not the instrument — is the source.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eS700 showing erratic battery percentage at reboot after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe S700's battery indicator is calibrated against voltage thresholds it learned from the previous pack's discharge curve. When a new 13000mAh cell is installed, the instrument's fuel gauge hasn't yet mapped the new pack's voltage-to-capacity relationship, so it displays inaccurate percentages for the first one or two full cycles. This isn't a fault in the battery or the instrument. Run the pack down to the auto-shutoff point, then charge it fully without interruption. After one or two complete cycles the indicator stabilises against the new cell's actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43303968866394,"sku":"BWCS-DRS700SL-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43303968899162,"sku":"BWCS-DRS700SL-2","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43303968931930,"sku":"BWCS-DRS700SL-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRS700SL_1.webp?v=1777520716","url":"https:\/\/batteryweb.com\/products\/deli-s700-broadcast-tv-signal-spectrum-analyzer-replacement-battery-74v-13000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
