It fits the T70\/2, T70\/2 iKontrol, IK2, and PUPITRE IK2 remotes. These are handheld industrial wireless transmitters used to operate overhead cranes and hoists from ground level.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT70\/2 and IK2 platform compatibility:\u003c\/strong\u003e\n    All four fit models share the same 3.7V single-cell architecture and BT11K form factor. The BMS handshake and connector pinout are identical across the T70\/2, T70\/2 iKontrol, IK2, and PUPITRE IK2 — one cell covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the T70\/2 platform. The BMS accepted the cell without fault codes, held stable voltage under simulated solenoid activation, and cut off cleanly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during idle periods:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between jobs. If the cell drops below 2.5V, the BMS enters deep-discharge lockout and the remote will not power on even with a charger connected. Charge the battery once a month during any extended idle period to prevent this.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on a freshly installed BT11K\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen an operator triggers a crane movement command, the remote's internal relay or solenoid draws a short inrush current spike. If the replacement cell is at storage voltage rather than full charge, that spike can push the BMS over its overcurrent threshold and trip a temporary cutoff. The remote appears to die mid-command, then recovers after a few seconds. Fully charging the cell before first use keeps the internal voltage high enough that the BMS handles the inrush without tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery warning immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells ship at approximately 3.6–3.7V storage charge — below the 4.2V full-charge threshold. The T70\/2 firmware reads cell voltage directly and flags anything under its low-battery threshold as a warning, even on a brand-new cell. This is not a faulty battery. Connect the remote to its charger and bring the cell to 4.2V before putting the remote back into service.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360064798810,"sku":"BWCS-KUT700BL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360064831578,"sku":"BWCS-KUT700BL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360064864346,"sku":"BWCS-KUT700BL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KUT700BL-1.webp?v=1778610769","url":"https:\/\/batteryweb.com\/products\/ikusi-t702-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
