Is it safe to replace our usual UPS power supply with a lithium battery one?
Compared to the traditional lead-acid batteries, lithium batteries have quite a few advantages. For the same power capacity, they are more lightweight and compact, plus they can handle more charge-discharge cycles, which means a longer lifespan. Nowadays, many places like data centres, hospitals, and communication base stations are particularly suitable for using Lithium UPS.
However, lithium batteries have their own "temper." If the temperature gets too high or they suffer a severe impact, they can experience "thermal runaway"—where the battery overheats and can even catch fire. This is indeed a bit worrying.
How is safety ensured?
The good news is, lithium battery UPS units come with a Battery Management System (BMS). The moment the BMS detects dangerous situations like over-voltage charging, over-discharging, or a short circuit, it can immediately identify the fault, cut off the current, and nip the danger in the bud.
Brands like Shanshuo's Lithium UPS also come with built-in multiple protection features like **reverse connection protection, over-charge protection, and over-load protection** for added safety.
Furthermore, most modern Lithium UPS use LiFePO4 batteries.
Most importantly, the lithium batteries used in modern UPS are predominantly Lithium Iron Phosphate (LiFePO4). Compared to other types of lithium batteries, this chemistry is much more stable and significantly safer, making it far less likely to run into problems.
So, in summary, as long as you choose a proper product with comprehensive safety features that uses LiFePO4 batteries, a Lithium UPS is actually very safe and reliable.
