It replaces the original pack when capacity has faded or when a spare is needed to sustain continuous field and bench operations. Voltage and cell count match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eREI DPA-7000 and TPS2000B platform fit:\u003c\/strong\u003e\n    The DPA-7000 and TPS2000B series share a common 11.1V three-cell Li-ion architecture and the same bay connector pinout. The BMS handshake on this pack mirrors the communication protocol the instrument expects at power-on, so the fuel gauge reads accurately from the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through instrument power-on, probe initialisation, and sustained sensor logging. The BMS held the voltage rail steady through probe power-up current spikes and did not trip cutoff under the combined draw of active measurement and backlit display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment calibration step:\u003c\/strong\u003e\n    After installing this pack, run a full calibration cycle through the instrument menu before field deployment. The DPA-7000 maps battery state during calibration — skipping this causes premature low-battery warnings on the first measurement session even when the pack is fully charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the DPA-7000 sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. If a pack drops below approximately 2.5V per cell (7.5V total for a 3S pack), the BMS enters a protective sleep state and will not respond to a standard charger. The charger sees no load handshake and reports the pack as absent or faulty. To recover, apply a low-current pre-charge — most Li-ion chargers have a recovery or wake mode that trickle-charges at around 0.1C until cell voltage climbs above 3.0V per cell, at which point the BMS re-initialises and accepts a normal charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or logging session resetting mid-measurement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained sensor load on the DPA-7000 draws more current than standby, and a degraded or partially discharged cell can sag below the instrument's minimum input voltage under that load. When voltage drops below roughly 10.2V on an 11.1V pack, the instrument's power manager triggers a soft reset to protect the measurement ASIC. This appears as a mid-session reboot or data loss rather than a clean shutdown. Charge the pack fully to 12.6V before any extended logging session and check that the battery contact pins in the bay are clean — oxidised contacts add resistance and worsen voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360432816218,"sku":"BWCS-GME300MX-1","price":238.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360432848986,"sku":"BWCS-GME300MX-2","price":284.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360432881754,"sku":"BWCS-GME300MX-3","price":318.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GME300MX-1.webp?v=1778614685","url":"https:\/\/batteryweb.com\/products\/tektronix-rei-dpa-7000-replacement-battery-111v-6700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
