Why do you need a BMS for your lithium battery pack

The Battery Management System (BMS) includes sensor functions for all key battery pack parameters such as voltage, current, charge/discharge rate, discharge rate, temperature and other parameters. 

BMS protects your lithium battery from overcharging, overcharging, discharging and draining and is essential to protect it from explosions, fire and damage. A lithium-ion battery with BMS offers significantly better battery life than any other lithium-ion battery. 

Li-ion batteries are much lighter than lead-acid batteries and offer deeper discharges and more service cycles, but they also have their limitations. 

DC fast charging is capable of charging up to 80% of an electric vehicle’s battery in just a few seconds, greatly speeding up the charging of electric vehicles.  

When Sony introduced the first lithium-ion batteries in 1991, they were aware of the potential safety risks and produced a battery with a direct current fast-charging capability of 1.5 volts. 

Due to the higher cell voltage of the lead acid, the risk of corrosion and damage to the lithium cells is considerably higher, against which one must protect oneself with much stricter charging tolerances. A BMS is primarily a circuit board that manages the lithium cell and protects it from hot charging and cold discharging, which can lead to permanent damage. 

Most lithium batteries manufactured in Europe now have a BMS built into the battery, which protects it and ensures that it is shifted correctly while driving. If you get a cheap Chinese import from DHgate, Aliexpress they usually don’t. They also falsely advertise capacity which leads to overcharging and potentially to explosions
