It fits the internal battery bay directly and matches the original voltage rail and connector. Capacity is 4.81Wh, sourced to the E3MIO2135211 specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEZ-Road and PEZ120 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, 3.7V nominal rail, and BMS handshake protocol — one cell covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a PDA-class test rig.

The BMS on the EZ-Road triggers a low-voltage shutdown faster under GPS and screen load than at idle. The fix is straightforward: charge the new battery to 100% before booting into navigation mode. Do not rely on the charge indicator alone — let it complete a full cycle first.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEZ-Road stuck on boot screen after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA cell below approximately 3.5V may not supply enough current for the boot sequence to complete — the device stalls at the splash screen or restarts in a loop. This is not a firmware fault. Connect the unit to a charger and leave it for at least 30 minutes before attempting to power on again. Once the cell reaches a stable charge above 3.6V, the boot sequence completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415947542618,"sku":"BWCS-MIO168SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415947575386,"sku":"BWCS-MIO168SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415947608154,"sku":"BWCS-MIO168SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIO168SL-1.webp?v=1779758396","url":"https:\/\/batteryweb.com\/products\/pharos-ez-road-replacement-battery-37v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
