The lithium-based battery is here to stay. Where lead acid batteries first dominated the market, you are increasingly seeing these being replaced by lithium-based technology. Benefits of this techology are:

• Higher charge and discharge currents compared to lead-acid batteries
• Safer during normal usage (with BMS)
• No shortened life when discharged below 50%, unlike lead acid
• No maintenance

It is important that various parameters, such as voltage and temperature of each battery cell, are constantly monitored to ensure that the battery lasts as long as possible and is not damaged.
Contrary to what is sometimes thought, this does not only apply to lithium-based batteries. It is also important for the older lead-acid battery, because overcharging lead-acid batteries produces Hydrogen gas. Thus, there are many cases of lead-acid batteries that have caused explosions. The great advantage of some lithium-based batteries, including LiFePO4, is that overcharging causes less violent effects.
The 123\SmartBMS will prevent undercharging, overcharging and many other situations which have negative effects, so you can enjoy your energy storage for as long as possible.
