Now the price of lithium power batteries has been relatively low, commonly used in products such as four-axis UAVs, so it is possible to make lithium battery UPS at a much closer cost. On the other hand, lead-acid batteries are not resistant to discharge into the void whereas lithium-ion batteries (through protective circuits) can discharge safely into the void, so lithium-ion batteries have some advantages.

So now you can see more lithium battery UPS on the market, but the price is still much more expensive for the same size, at least more than twice the price.
