It slots into the same 56V ARC Lithium platform that powers EGO's brushless chainsaw motors. Voltage and capacity match the OEM spec — no adapters, no modifications.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model compatibility — CS1400 to CS1604:\u003c\/strong\u003e These chainsaws share the same 56V power rail and battery connector, so one battery pack covers the full range without any wiring differences.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under chainsaw motor load and cut off cleanly at the low-voltage threshold without tripping a fault state.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use tip for Li-ion on high-draw tools:\u003c\/strong\u003e Run two or three full discharge-and-charge cycles before heavy cutting sessions — this lets the BMS calibrate capacity readings accurately for a high-current brushless motor draw.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy 336Wh matters on a brushless chainsaw\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA brushless motor at 6,800 RPM pulls hard current spikes, especially when biting through dense hardwood. Higher watt-hour capacity means the pack sustains voltage under those spikes rather than sagging. Voltage sag slows chain speed mid-cut and puts extra heat into both the motor and battery cells. A 336Wh pack at 56V gives the BMS more headroom to manage those demands.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery showing \"charged\" but chainsaw stalls under load — here's the cause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the saw runs at idle but bogs or cuts out during a cut, the BMS is hitting its overcurrent protection threshold. This usually happens when the chain is dull or the bar oil is low, forcing the motor to draw excessive current. Sharpen the chain, check bar oil, then reset the battery by removing it for 30 seconds and reseating it firmly. A worn chain is the most common trigger on EGO chainsaws — not a faulty battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175812300890,"sku":"BWCS-EHT400PX-1","price":266.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175812333658,"sku":"BWCS-EHT400PX-2","price":316.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175812366426,"sku":"BWCS-EHT400PX-3","price":354.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EHT400PX-1.webp?v=1775236243","url":"https:\/\/batteryweb.com\/products\/ego-cs1400-replacement-battery-56v-6000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
