It replaces OEM part number N5-4345. The Dynamic 2100 uses this pack to drive the tensioning motor and welding mechanism through repeated strapping cycles in warehouse and logistics environments.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDynamic 2100 fit:\u003c\/strong\u003e\n    The Dynamic 2100 tensioning motor draws current in sharp peaks — especially at maximum tension. This pack's cell configuration and connector match the original voltage rail and BMS handshake, so the tool's tension and weld cycles run as expected without tripping a false fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through full tensioning-and-weld cycles on the Dynamic 2100 bench rig. The BMS held under peak motor load at maximum tension setting, and the weld trigger received consistent voltage through the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold warehouse start-up:\u003c\/strong\u003e\n    In warehouses below 10°C, a cold Li-ion cell can't sustain the current spike the tensioning motor demands on its first hard pull. Let the pack sit at room temperature for 15–20 minutes before the first cycle of the shift — this prevents a BMS overcurrent trip on start-up that looks like a faulty battery.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during the tensioning cycle on the Dynamic 2100\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dynamic 2100's tensioning motor draws current in a steep ramp as strap tension increases, peaking sharply at maximum tension. If the BMS reads that spike as an overcurrent event, it trips and kills power mid-cycle — the tool stops before the weld fires. This happens most often with cold cells or packs that sat discharged for several weeks. A full charge cycle restores cell voltage to the acceptance threshold, and the BMS clears the fault on the next power-on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light on a new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs shipped or stored for extended periods can drop below 10V — the minimum acceptance voltage most Dynamic 2100 chargers will recognise. When cell voltage is too low, the charger rejects the pack and shows a fault or error indicator instead of beginning a charge cycle. Place the pack on the charger and leave it for 10–15 minutes without removing it — many chargers run a low-current recovery pulse before switching to the main charge phase. If the fault clears and the charge indicator activates, the pack has recovered; if it stays faulted after 20 minutes, check that the charger output voltage reads at least 16.8V at the terminals with a multimeter.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416040276058,"sku":"BWCS-FRC210PW-1","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416040308826,"sku":"BWCS-FRC210PW-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416040341594,"sku":"BWCS-FRC210PW-3","price":124.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/fromm-dynamic-2100-replacement-battery-144v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
