It fits the LB1200, LB1200 Spyder Ka, LB1500, LB1500 SpyderEVO, and several additional models in the same voltage family. Direct swap — same connector, same BMS handshake protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLB1200 and LB1500 platform compatibility:\u003c\/strong\u003e\n    Both series run the same 25.9V (7S Li-ion) architecture with an identical battery bay and BMS communication line. A single replacement covers both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the LB1200 charge cycle and simulated blade-motor inrush at startup. The BMS held through repeated inrush events without tripping and accepted a full charge termination cleanly at 29.4V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip before spring restart:\u003c\/strong\u003e\n    If the mower sat in an unheated garage through winter, bring the battery indoors for at least one night before charging. Below 10°C, Li-ion internal resistance rises enough that blade motor inrush current on a cold pack can trip the BMS before the mower takes its first cut.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LB1200 blade motor draws significantly more current in dense or wet grass than in dry, short turf. If the instantaneous draw spikes beyond the BMS overcurrent threshold — typically during a direction change mid-row — the pack shuts down as a protection measure. This is not a battery fault; it is the BMS doing its job. Let the mower sit for five minutes before restarting: the BMS will reset once the cell temperature and load conditions normalise. If cutouts repeat consistently in one zone, reduce the mowing schedule frequency so grass height stays lower on each pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat in storage all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over months. If the pack voltage drops below roughly 20V during a long storage period, many chargers will refuse to start a charge cycle — the pack voltage is too low for the charger's acceptance window. The fix is a brief recovery charge: some compatible chargers have a \"recovery\" or \"soft start\" mode that trickle-charges at low current until the pack climbs above the acceptance threshold. If yours does not, a bench power supply set to 25.9V at 0.5A for 15–20 minutes will bring the pack back into the normal charge window. Check cell voltage is above 21V before attempting a standard charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381293252698,"sku":"BWCS-WRN110VX-1","price":204.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381293285466,"sku":"BWCS-WRN110VX-2","price":243.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381293318234,"sku":"BWCS-WRN110VX-3","price":271.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WRN110VX-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/lawnbott-lb1200-replacement-battery-259v-10200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
