For batteries it tends to be multiple of the battery cell voltages. So 48v is probably so you could wire 4x12v batteries in series but that is a guess. With tool voltages this tend…

Something is very amiss with the QLD data. A better site for exploring composition of generation is https://opennem.org.au/energy/qld1/ . That said, the result is about right for C…

Concrete setting times depend on ambient temperature. Too cold and concrete takes longer to achieve the necessary strength to start the next level. Admixtures and other techniques …

Worth pointing out that if you're patient with setting times, you can use portland cement substitutes (fly ash, ground blast furnace slag) as a substitute for portland cement. Slow…
