It also goes into lower float voltage when the battery is full. Doesn't have the limitations of a traditional relay.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReverse Charging Feature:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe BB1225 is able to charge in both directions. Provided there is over 13.2V on the leisure battery (13.5V if lithium) and the starter battery is below 13V the BB shall allow approximately half current to flow back to the starter battery up to about 13.4V (float voltage). It simply allows the starter battery to remain topped up when there is surplus energy in the domestic battery. This feature will NOT drain your domestic battery - it simply takes surplus. Once your alternator \/ engine turns on or you provide the BB with an ignition signal the BB reverts to normal charging of the leisure battery. This mode can be disabled, but is on as default.\u003cbr\u003eThis is ideal for allowing the starter battery to remain topped up when you have solar \/ wind \/ charger - charging up your leisure battery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eParalleling multiple battery to battery chargers together?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThere are no problems installing multiple BBs together in parallel to increase the power. For example, you can parallel a BB1225 with a BB12120 to get 145A of charge current. Likewise, two BB1270 units for 140 amps total or two BB12120 units for total of 240 amps directed to house bank charging from one alternator or two alternators as input sources is a common application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1) Redundancy, having multiple DC-DC chargers can help with redundancy. If one was to get damaged, the other BB(s) shall continue charging.\u003c\/p\u003e\n\u003cp\u003e2) Fine tuning the current. As each BB has 3 different power levels, adding multiple BBs together gives you 6, 9, 12 etc.. different power levels. For example, if you wanted 80A you could get a BB1270 and a BB1225 and set the power levels to 85% each via the BBR remote (to give you approximately 80A). Thus, giving you large levels of flexibility to hone in to a specific charge current.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdjustable Current Limit:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe default current setting for the BB range is 100% - meaning that the performance default is full power. If you wish to reduce the performance of the BB, here you can set to 85% or 65% charge rate. Examples of why you may wish to reduce performance:\u003c\/p\u003e\n\u003cp\u003e1) if you have solar panels and the weather is good, by reducing the power of the BB, you shall conserve fuel.\u003c\/p\u003e\n\u003cp\u003e2) The alternator is better suited running at slightly lower current than what was expected or you don't want the alternator to work as hard.\u003c\/p\u003e\n\u003cp\u003e3) It may be recommended by your battery supplier to charge the battery up at a slightly lower current. If one of your lithium batteries within your leisure battery bank fails, you may be exceeding the C rating of the remaining batteries.\u003c\/p\u003e\n\u003cp\u003e4) future proofing. If you have installed a high powered BB, in the assumption that one day you shall put a larger alternator on and\/or more batteries in your system. You can reduce the power for the immediate install and increase the performance of the unit at a later date.\u003c\/p\u003e","brand":"Sterling Power","offers":[{"title":"Default Title","offer_id":48171834867902,"sku":"BB1225","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6359\/2382\/files\/BB1210_4b512557-2261-4598-b767-461b1ae4750f.jpg?v=1784315685","url":"https:\/\/www.vanlifeoutfitters.com\/products\/sterling-power-12v-dc-dc-battery-charger-25-amp-bb1225","provider":"Vanlife Outfitters","version":"1.0","type":"link"}
