{"product_id":"sterling-auxiliary-battery-charger-3-amp","title":"Sterling Auxiliary Battery Charger 3 Amp","description":"\u003cp\u003eThe battery charger\/maintainer enables an extra battery bank to be kept 'topped up' from the main battery bank which has the charging device(s) connected to it (e.g. alternator, battery charger, solar cell\/wind turbine etc.) The battery charger\/maintainer works by detecting when the main battery bank reaches 13.3V and allows the excess power to be transformed to the extra battery bank with only a minor voltage drop of 0.2V. This allows the extra battery bank to be 'maintained' by charging it with several amps. This device is not a high charging device, it's a maintenance device.\u003c\/p\u003e","brand":"Sterling","offers":[{"title":"Default Title","offer_id":57812223885693,"sku":"VS-347","price":156.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/0199\/3204\/files\/VS-347_a228e135-d1d7-477a-9b90-29185eb86cbe.jpg?v=1770940396","url":"https:\/\/waterworldsports.co.uk\/products\/sterling-auxiliary-battery-charger-3-amp","provider":"waterworldsports.co.uk","version":"1.0","type":"link"}
