How Does Server Rack Battery Work?
Server Rack Battery usually consists of a battery management system (BMS), a square battery, an operation panel, a bracket, and a cover. The communication protocol port includes RS485, RS232, CAN protocol, etc. It can support the coexistence of unlimited units, which helps the parallel connection of multiple batteries to expand capacity and power.
⑴ Safety
Server rack battery is a green new energy source, stable and more environmentally friendly.
Rack-mounted lead-acid batteries have the potential to leak toxic gases.
⑵ Performance
Server rack batteries have been proven to have higher energy density and provide a more stable current.
Rack-mount lead-acid batteries may also have a relatively high energy density, but the current supply is not constant and decreases as the battery drains.
⑶ Stability
When placing any lifepo4 battery in a server rack battery, it is vital to consider the stability of the battery in question, and lithium batteries are a more stable choice.
Rackmount lead-acid batteries are much less stable due to their liquid acid composition.
⑷ Charge and Discharge Cycle
The charge-discharge cycle of the server rack battery is better, the charge can reach 100%, and the discharge can get 0%, which has little effect on the battery.
Rackmount lead-acid batteries should only be charged to 80% and discharged to 20% to avoid adverse effects on the battery itself.
The cycle life of lithium batteries can be as high as 6000 times, much higher than that of lead-acid batteries.
⑸ Weight
Under the same capacity, lithium batteries are lighter than lead-acid batteries.
