It slots into the same battery compartment as the original B-87C and BAT320 packs. The T-298S and T320 are used in security, logistics, and enterprise field operations where continuous radio contact is non-negotiable.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT-298S and T320 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.8V battery bay, connector pinout, and BMS handshake protocol — one pack fits both. The BMS on each radio uses the same voltage thresholds for charge acceptance and bar-indicator readout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and full-transmit draw on the T320 platform. The BMS handled the PTT current spike without tripping into overcurrent lockout, and voltage held steady across sustained RF output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on a charger dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Inrico dock requires a clean contact cycle to complete the BMS handshake before it begins charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the T-298S drops to reduced TX power mid-shift on a fresh pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell ships at storage voltage — typically around 3.6V — not at full charge. When the radio draws peak transmit current from a partially charged cell, internal resistance causes a sharper voltage sag than it would on a fully charged pack. The T-298S interprets that sag as low battery and steps down TX power to protect the RF stage. Running a full charge cycle before field deployment eliminates this behaviour entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting the B-87C\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T-298S and T320 use simple voltage-threshold bar indicators — each bar corresponds to a voltage band, not a calculated charge percentage. A new cell at storage voltage sits in a lower band and displays one or two bars even though the pack is not depleted. Charge the battery fully in the dock until the indicator goes solid green. After a complete charge cycle the bar display will read correctly at the top threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426248065114,"sku":"BWCS-NSR320TW-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426248097882,"sku":"BWCS-NSR320TW-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426248130650,"sku":"BWCS-NSR320TW-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NSR320TW-1.webp?v=1779930524","url":"https:\/\/batteryweb.com\/products\/inrico-t-298s-replacement-battery-38v-3400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
