You can select it among the product's purchase options. It will let you lower the charge voltage to around 53-54V, slightly reducing power.\u003c\/p\u003e\n\u003cdiv class=\"info-box\"\u003e\n\u003cimg src=\"https:\/\/litio.store\/cdn\/shop\/files\/info.png\" alt=\"DC-DC 12V\/24V-48V Sterling Power BB1248120 Battery to Battery charger DC-DC 12V 120A 48V 30A 11608\" data-original=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2510\/0896\/files\/info.png?v=1720924851\" data-files=\"info.png\" loading=\"lazy\"\u003e\n\u003cdiv class=\"info-box-content\"\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Compared to the BB124865, the BB1248120 is larger and more powerful.
