People buy the trollie UPS’es, great excitement, costs wot ±R10k
Then they add more and more onto it, 1-3 years later, the batteries die.
The cost of replacing the 2 x 12v 100ah batteries, or some such, the plan stops that day.
Some make the sums, they “made a profit” as their business continued, helped them “earn”, so they replace the batteries, or upgrade.
For most using it for convenience, ±R10k down the tubes.
I’m now sitting with people about UPS’es. We don’t have R10k … what are the options for Wifi, laptop, screen and maybe even TV?
There is no cheap long-lasting plug and play never look back option.
