It slots into the same battery compartment as the OEM cell and runs at the same voltage rail — no adapter required. Capacity listed here comes from the product specification, not estimated figures.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTM70 and IK3 transmitter compatibility:\u003c\/strong\u003e\n    The TM70\/3, TM70\/8, IK3, and T70\/3 series all share the same 4.8V NiMH battery platform and connector footprint. The BMS on each transmitter expects a 4-cell NiMH pack — swapping in a different voltage or chemistry will cause the remote to reject the pack or fail to initialise.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a TM70 transmitter and cycled it through full charge and discharge. The BMS accepted the cell immediately, held the communication link stable through repeated solenoid activation commands, and flagged low-battery at the correct threshold without premature dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge cycle for infrequent crane use:\u003c\/strong\u003e\n    Crane remotes often sit unused between shifts or during shutdowns. NiMH cells left uncharged for more than 30 days can drop below the BMS recovery threshold. Charge this battery once a month during any idle period to prevent a deep-discharge condition that a standard charger cannot reverse.\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 the TM70 transmitter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the TM70 sends a solenoid or relay activation command, the transmitter draws a short inrush current spike that is higher than its normal standby draw. A degraded or deeply discharged NiMH pack cannot hold its voltage through that spike — the BMS interprets the sag as a fault and cuts the output. This looks like the remote freezing or restarting mid-command. A fully charged, healthy 2000mAh pack at 4.8V nominal has enough current headroom to absorb the activation spike without tripping the BMS cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low-battery indicator immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new NiMH pack ships at storage voltage — typically 3.8V to 4.2V for a 4-cell pack — not at full charge. The TM70 transmitter reads that lower resting voltage and correctly flags it as low battery. This is not a fault with the battery or the remote. Connect the battery to the Ikusi charger before first use and allow a full charge cycle. The low-battery indicator will clear once the pack reaches its nominal 4.8V operating voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360073416794,"sku":"BWCS-KUT271BL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360073449562,"sku":"BWCS-KUT271BL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360073482330,"sku":"BWCS-KUT271BL-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KUT271BL-1.webp?v=1778610751","url":"https:\/\/batteryweb.com\/products\/ikusi-tm703-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
