The H45 is a portable electric strapper used for tensioning and sealing plastic and polypropylene strap on cartons and pallets. Voltage and capacity match the original cell configuration exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH45 strapper compatibility:\u003c\/strong\u003e\n    The H45 runs a single 14.4V Li-ion pack that powers both the tensioning motor and the heat-seal weld cycle. The BMS must handshake at the correct voltage rail — a mismatched pack will not initialise the tool's control board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full tensioning sequences and heat-seal triggers. The BMS held current delivery stable through the motor's peak draw at maximum strap tension without tripping the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold warehouse storage tip:\u003c\/strong\u003e\n    In environments below 10°C, allow the battery to warm above that threshold before use. The tensioning motor draws sharp current at peak load — a cold cell's internal resistance climbs enough that the BMS can trip the protection circuit mid-cycle before the cell itself is depleted.\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 a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe H45 tensioning motor spikes current sharply at maximum strap tension — this is normal, but it stresses the BMS protection circuit on a new or cold pack. If the cell voltage drops momentarily below the BMS threshold during that spike, the circuit trips and the tool cuts out. This is not a faulty battery. Warm the pack above 10°C and run two or three partial tensioning cycles to let the cells stabilise before pushing to full tension load. If cutout persists on a fully charged, warm pack, check the battery contacts for oxide buildup — contact resistance amplifies voltage sag under peak draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light on a new pack after the tool has been stored\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that have sat discharged for an extended period drop below the charger's acceptance voltage threshold — typically around 10–11V on a 14.4V pack — and the charger refuses to start a charge cycle, showing a fault or error indicator instead. This is a self-protection response in the charger, not a sign the battery is dead. Some chargers have a recovery or \"wake\" mode; if yours does, activate it. If not, a bench power supply set to 14.4V at 200mA applied for 10–15 minutes can bring the cell voltage back above the acceptance threshold so the standard charger will engage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416245076058,"sku":"BWCS-OPT250PW-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416245108826,"sku":"BWCS-OPT250PW-2","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416245141594,"sku":"BWCS-OPT250PW-3","price":108.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPT250PW-1.webp?v=1779761098","url":"https:\/\/batteryweb.com\/products\/transpak-h45-replacement-battery-144v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
