It features automatic alternator detection via the D+ signal or voltage sensing. We recommend using 10mm² to 16mm² cabling (depending on length) to minimize voltage drop. A Battery Temperature Sensor (BTS) is included to optimize charging based on real-time conditions. Questions & Answers Is this a genuine original part? This is a premium quality TBB Power part, supplied by Solarika, manufactured to meet or exceed original equipment (OE) standards for vehicle battery management. How do I know if it is compatible? If you have a 12V vehicle system (Euro 5, Euro 6, or older) and need to charge a leisure battery bank at up to 45A, the DM1245 is an ideal fit. Check your required charge current against your battery manufacturer's recommendations. Does this unit include a solar MPPT input? No, the TBB-DM1245 is a dedicated DC-to-DC (alternator-to-battery) charger. For dual solar and alternator charging, please look for the TBB Nemo or DMT series units. Note: Please verify your system voltage and battery chemistry requirements against the specifications above before purchasing.","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738751700_05943100.png?v=1789040079","href":"/product/tbb-power-45a-dm-12v-dc-to-12v-dc-battery-to-battery-charger-tbb-dm1245.html","buy_url":"https://xyjpsn-3p.myshopify.com/products/tbb-power-45a-dm-12v-dc-to-12v-dc-battery-to-battery-charger-tbb-dm1245","buy_url_source":"shops.shop_domain + product.handle","seller_name":"xyjpsn-3p.myshopify.com","seller_url":"https://xyjpsn-3p.myshopify.com/","return_policy_url":"https://xyjpsn-3p.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738751700_05943100.png?v=1789040079","alt":null,"position":0},{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738751707_46341300.png?v=1789040080","alt":null,"position":1},{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738751705_25385900.png?v=1789040080","alt":null,"position":2},{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738751702_56549600.png?v=1789040080","alt":null,"position":3},{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738751709_67949000.png?v=1789040079","alt":null,"position":4},{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/57d76e1e-b442-4b29-9bdb-9020265d96c0.png?v=1789040080","alt":null,"position":5},{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/3d661d59-1f6d-4a1f-b648-9eecc41616af.png?v=1789040081","alt":null,"position":6}],"related":[{"handle":"victron-cyrix-ct-230a-12-24v-intelligent-battery-combiner","title":"Victron Cyrix-ct 230A 12/24V Intelligent Battery Combiner","category":"DC to DC Battery Chargers","price":"$77.99","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/victron-cyrix-ct-230a-1224v-intelligent-battery-combiner-4boats_7cdc45c6-f1b3-468e-a620-6b16efc6045c.jpg?v=1789040636","sku":"CYRIX-230A","href":"/product/victron-cyrix-ct-230a-12-24v-intelligent-battery-combiner.html"},{"handle":"tbb-power-20a-dm-12v-dc-to-12v-dc-battery-to-battery-charger-tbb-dm1220","title":"TBB Power 20A DM 12V DC to 12V DC battery-to-battery charger","category":"DC to DC Battery Chargers","price":"$91.00","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1738691655_89263000.png?v=1789040083","sku":"TBB-DM1220","href":"/product/tbb-power-20a-dm-12v-dc-to-12v-dc-battery-to-battery-charger-tbb-dm1220.html"},{"handle":"20a-12v-dc-to-12v-dc-automatic-multi-stage-battery-to-battery-charger-with-solar-input-for-lead-acid-calcium-or-lithium-ion-batteries-dcdc-20a","title":"20A 12V DC to 12V DC Automatic Multi-Stage Battery-to-Battery Charger with Solar Input for Lead Acid, Calcium or Lithium-ion Batteries","category":"DC to DC Battery Chargers","price":"$77.99","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/20a-12v-dc-to-12v-dc-automatic-multi-stage-battery-to-battery-charger-with-solar-input-for-lead-acid-calcium-or-lithium-ion-batteries-4boats_d7af91fe-9f0a-4c22-9700-f5cf7fd4772c.jpg?v=1789041060","sku":"DCDC-20A","href":"/product/20a-12v-dc-to-12v-dc-automatic-multi-stage-battery-to-battery-charger-with-solar-input-for-lead-acid-calcium-or-lithium-ion-batteries-dcdc-20a.html"},{"handle":"90a-12v-dc-to-12v-dc-advanced-automatic-multi-stage-battery-to-battery-charger-for-lead-acid-and-lithium-batteries-dc1212-90","title":"90A 12V DC to 12V DC Advanced Automatic Multi-Stage Battery-to-Battery Charger for Lead Acid and Lithium Batteries","category":"DC to DC Battery Chargers","price":"$214.50","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/1740489429_67926900.png?v=1789040133","sku":"DC1212-90","href":"/product/90a-12v-dc-to-12v-dc-advanced-automatic-multi-stage-battery-to-battery-charger-for-lead-acid-and-lithium-batteries-dc1212-90.html"}]}}
