The low-voltage battery provides 16 V for all of the cars accessory functions. Similar to the lead acid battery in a gas car. Since you have a long range, your high voltage, or a big battery is a lithium ion using NCA technology. With this battery you want to recharge the car daily below 90%. i do 85% in winter and 80% in summer.
The terminals of the Victron Smart lithium batteries are always live and all loads/chargers have to be controlled by the BMS. Loads connected directly to the battery can discharge the battery to a dangerous low level. If installed correctly all loads are disconnected by the BMS in case of low battery/cell voltage.
As a result, the BMS may see 11.8 volts on one of the batteries as a low voltage condition, triggering a shutdown. Low SOC: When a battery is discharged, the voltage drops gradually. Typically, in the low SOC range of lithium batteries, the voltage may be
During normal operation of a lithium battery, small differences between cell voltages occur all the time. The battery has a cell imbalance, causing premature low-voltage alarms, which in turn causes the BMS to turn loads off. Please refer to section How to recover an imbalanced battery. When recharging the battery after a low voltage

Using a multimeter to measure the battery voltage directly is the best and quickest way to determine if the voltage is too low. If the voltage of your battery is below 12.2 volts, it is the sign of a low battery. What happens if
This comprehensive guide will delve into the causes of low battery in lithium-ion batteries, provide insights on handling such situations, and shed light on the long-term battery health implications.
There should also be a low voltage limit for the lithium battery discharge. When the cell voltage is less than 2V, part of the material begins to be destroyed. And because the battery will self-discharge, the longer the battery not charged, the battery voltage will be lower. therefore, it is best not to discharge the cell volt to 2V .
A battery can show low voltage right after charging due to issues like a damaged cell, high internal resistance, or alternator problems. For example, a lithium-ion battery might hold only 70% of its original capacity after two years, leading to low voltage readings post-charge. The most common causes of low voltage after charging
