This differs significantly from charging lithium batteries and their constant current stage and constant voltage stage. Occasionally, there are equalization and maintenance stages for lead – acid batteries as well. When charging a lead – acid battery, the three main stages are bulk, absorption, and float.
If the increase is excessively rough, it can lead to serious APD damage, but your alternator, batteries, and regulators have been protected. These devices turn on with a small resistive load of milli-amp hours to reduce a possible increase in voltage due to cables breaking or any other issues. Sterling Alternator Protection devices (APD) are also available in our store to prevent damage from surges. They can regulate the current up to 220 amps and prevent damaging the alternator during a long drive. If you have less than three of our batteries in your system, a BIM isn’t exactly required, and instead, you can use a standard isolator. The BIM provides an extra layer of safety to make sure you don’t damage your system of three or more lithium batteries when charging from the alternator during a long drive. It can certainly take more power from the alternator when compared to lead-acid batteries. It helps with simultaneously monitoring the house and starter bank and has high internal resistance. Charging from your alternator is a great option, however, you will need some extra equipment, like a battery isolation manager (BIM).Ī well-known industry tool, this component is programmed specifically to run with our batteries. The batteries naturally float at 13.6V but reaching 14.6V is ideal and needs to happen in order to engage its balancing mechanisms.Īlternator charging is a common method to recharge lithium batteries. While lithium batteries technically don’t need to be floated, a good majority of the devices out there still have a float charge mode. Aim for a range between 14.2V and 14.6V with bulk and absorption stages and for the float stage, 13.6V is best. You also can mix battery chemistries safely with this device, such as your AGM starting battery to your lithium house bank. The Victron Orion-TR Smart DC-DC isolated charger is an adaptive, three-stage charger with algorithms for bulk, absorption, and float options. It’s great for those with trolling motor applications or those with battery systems connected in series.įor alternator charging, we often recommend using a DC-to-DC charger or battery-to-battery charger. This device connects directly to the battery and is meant for single-battery charging.

We also frequently suggest Victron’s IP-65 Blue Smart Charger because it’s waterproof, Bluetooth compatible, and has a charging profile for lithium batteries and other battery chemistries. bulk and absorption: 14.2-14.6 volts (aiming for a sweet spot of 14.4 is recommended).With Solar Charge Controllers we recommend the following settings: One component we often recommend is the Victron Energy SmartSolar MPPT charge controllers for systems equipped with solar. We have plenty for purchase, so check out our store if you’re looking for more power! Our team also recommends components from Progressive Dynamics and Magnum. They even offer the Victron Connect phone app where you can view all the details of your Bluetooth-capable devices. Battle Born is a master dealer of Victron components because they are reliable and well-built. There are three main ways to charge a system: solar, alternator, and shore.īattle Born Batteries only sells accessories from brands we know to produce quality products. Our team gets this question daily, and we have a blog post on charging LiFePO4 batteries that helps address that topic. How long does it take to charge lithium batteries?.What are the proper charging voltages for the 12V, 24V, and 48V lithium batteries?.The Lithium Battery Charging Cycle: to float or not to float?.Can I Charge My Lithium Batteries Using The Alternator?.Do I have to buy a special charger for LiFePO4 batteries?.
