It fits the A16, TS7, V98, and iRTK5 Host Bag. Capacity is 38.48Wh — sufficient for full field sessions without mid-day swaps.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA16, TS7, V98, and iRTK5 compatibility:\u003c\/strong\u003e\n    These units share the same 7.4V battery rail, BL-6800 footprint, and BMS handshake protocol. One battery pack covers all four instruments — no pin remapping or firmware flag needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through cold-start initialisation, satellite lock acquisition, and sustained RTK logging. The BMS held steady through the receiver's antenna power-up current spike without tripping into protection mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment calibration:\u003c\/strong\u003e\n    After fitting a new pack, run a full calibration cycle through the instrument menu before heading to site. The receiver maps battery state during calibration — skipping this causes premature low-battery warnings during your first measurement session, even when the pack is at 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 lockout after the A16 sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. If the pack drops below approximately 2.5V per cell, the BMS trips into deep-discharge lockout and the instrument won't power on — it won't even show a charging indicator. Place the battery on a compatible charger and leave it for up to 30 minutes; most BMS circuits will accept a trickle recovery charge at that threshold. Once cell voltage climbs above 3.0V per cell, normal charging resumes and the instrument will recognise the pack again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eInstrument shuts down during USB data transfer to PC\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eData transfer over USB adds a second draw on top of active receiver processing — combined load can pull the battery below the BMS cutoff threshold faster than field measurement alone. This usually happens when the pack has partial charge rather than a full one. Top the battery to 100% before connecting to a PC for data offload. If shutdowns persist, check that the USB cable is data-only and not simultaneously attempting to charge the instrument from a low-output port, which can confuse the power management circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360449101914,"sku":"BWCS-TRV980SL-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360449134682,"sku":"BWCS-TRV980SL-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360449167450,"sku":"BWCS-TRV980SL-3","price":113.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TRV980SL-1.webp?v=1778614761","url":"https:\/\/batteryweb.com\/products\/hi-target-a16-replacement-battery-74v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
