LiFePO4 chemistry suits this application — it handles the blade motor's repeated inrush spikes better than standard Li-ion. Compatible OEM part numbers include BAT6000A, MRK6103A, BAT6000C, BAT6001B, MRK6105A, and 57953070.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRS630 \/ RS635 \/ TS1800 platform fit:\u003c\/strong\u003e\n    These models share the same 25.6V battery rail, connector pinout, and BMS handshake protocol. The same pack slots across all three without modification to wiring or dock contacts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated blade-load draws matching thick-grass cutting resistance. The BMS held voltage within spec across repeated motor-start inrush events and did not trigger a false cutoff during sustained high-draw passes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSpring startup tip:\u003c\/strong\u003e\n    Before the first mow of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold LiFePO4 cells carry higher internal resistance, and the blade motor's inrush current can trip the BMS on a pack that hasn't warmed to ambient.\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 thick-grass or wet-grass cutting passes\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the RS630 hits dense or waterlogged grass, the blade motor pulls a hard inrush current to maintain RPM. If the battery's state of charge is already low — typically below 20% — the BMS can read that spike as an overcurrent fault and cut the output rail entirely. The mower stops and the dock light shows a battery fault. Let the mower sit off the dock for 60 seconds, then reconnect — the BMS resets once the fault timer clears. Keep the battery above 25% when scheduling mowing sessions in overgrown conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not accepting the pack after winter garage storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLiFePO4 cells self-discharge slowly but steadily over months. A pack stored uncharged through winter can drop below the charger's acceptance threshold — typically around 20V for this platform. The dock shows a solid fault LED and refuses to begin a charge cycle. To recover the pack, connect it to the charger and monitor voltage with a multimeter at the battery terminals. If voltage reads between 18V and 23V, leave the charger connected for 30–60 minutes — most Robomow docks include a trickle pre-charge mode that will bring the cells back above acceptance voltage before switching to full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381307310170,"sku":"BWCS-RRS630VX-1","price":187.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381307342938,"sku":"BWCS-RRS630VX-2","price":221.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381307375706,"sku":"BWCS-RRS630VX-3","price":248.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RRS630VX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/robomow-premium-rs630-replacement-battery-256v-6000mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
