![]() We appreciate you bringing up the point of the 12.2V cutoff. We believe you are meaning to respond to our white paper blog. If you have any other questions or concerns, please give us a call at 85 or send an email to. The BMS does not regulate incoming current, which is why there is a need for a DC to DC charger to regulate flow of current from the alternator to the batteries. Since it is Bluetooth enabled, you are also able to see some charging information on the app as well. These units will regulate the amount of current, and also act as an existing isolator. This will allow you to set a specific charge profile compatible with our batteries, and will ensure proper charging. The maximum recommended wire gauge is 6 gauge for this unit.įor alternator charging, we recommend using the Victron 12/12 – 30 Smart Charger for a number of reasons. These parameters can be customized for Battle Born Batteries with the use of the Victron Connect App as it’s a Bluetooth enabled device. The unit has a three stage charge profile with bulk, absorption, and float. The 12/12 Smart Charger is more versatile and works with smart/non-smart alternators. There is no actual charge profile on this unit, and the maximum wire gauge recommended is 10 gauge. This unit has a simple rotary dial that the output voltage can be set to we recommend 14.4v for Battle Born Batteries. The 12/12 converter is geared towards the use of a non-smart alternator. Hi Kevin, there are a few differences between the Victron 12/12 – 30 converter vs the Victron 12/12 – 30 Smart Charger. Here are a few FAQ videos that talk about charging LiFePO4 batteries. A float is unnecessary, since li-ion batteries do not leak charge, but a floating voltage under 13.6 V is fine. We recommend a bulk and absorption voltage of 14.4 V. ![]() The 12V Battle Born Batteries sit comfortably right in the middle of these ranges. The bulk and absorption voltages typically vary between 14.0 and 14.8 V, and the float can vary between 13.2 and 13.8 V. There is a wide variation among values for charging algorithms for lead-acid batteries. A closer look reveals that each algorithm has its own unique parameters, including: But battery chargers may also include multiple charging algorithms (typically classified as “AGM,” “SLA,” “Gel,” “Wet,” etc.). the max charging current) and a target battery voltage (12 V, 24 V, 36 V, 48 V, etc.). These stages combined sequentially form what is commonly called the “charging algorithm.” A battery charger may generally be classified by a charging current (i.e. The point of this stage is to keep the battery topped off, and account for the fact that lead-acid batteries tend to drain, even when there is no load connected. So, instead of turning off, the battery charger enters a third stage called the “float” stage, in which the charger drops to a lower voltage and holds at that voltage. However, a lead-acid battery will rapidly lose charge when the charger is disconnected. During absorption, the charger applies a constant voltage, called the “absorption voltage.” As the battery’s open-circuit voltage approaches the absorption voltage, the current flow steadily decreases down to zero.Īt this point, the battery is fully charged. Once the bulk voltage is reached, the charger enters a second stage, called the “absorption” charging stage. During this stage, the charger adjusts its applied voltage to deliver the maximum current to the battery.įor example, a 10 amp charger will deliver its maximum of 10 amps during this bulk charging stage, and the applied voltage will increase up to a maximum voltage, or “bulk voltage.” This is the first stage of the charging process – typically called the “bulk” charging stage. First, the charger can steadily increase its voltage in order to keep the current flow constant. The lithium battery charger can behave in several different ways during the charging process. During this process, the battery’s open-circuit voltage increases, approaching the applied voltage of the charger. When the charger’s applied voltage is higher than the open-circuit battery voltage, then the charging current flows. The lithium battery charger acts as a pump, pumping current upstream, opposite the normal direction of current flow when the battery discharges. Charging a LiFePO4 BatteryĬharging a LiFePO4 battery basically means applying an external voltage to drive current from the anode to the cathode of the battery. ![]() To begin the series we will discuss the basics of charging batteries, and the products will be covered in other segments. We’ve reviewed products that work well with our Battle Born LiFePO4 batteries. Every day we get questions about charging LiFePO4 batteries and lithium battery chargers.
