Battery power setup

[Earl]

Im once again looking at battery power for my 12v devices, ill look at laptops at another time.

Can have a charger plugged into the mains and the battery 247 or does it need to be off while the battery is in use?

I just need to take a 12v lead of the battery into my power distribution?

i have looked at 100ah batterys they cost around £80.

what lead do i use to connect the batter to a 2.1m socket on a ditrubution hub?

How many devices can i run of it? can i feed a mount hub pro of a distrubution hub (daisy chaining)

A link to the right charger would be appreciated

Most people go for a Cemax charger. It supplies sufficient current to keep the battery tip top and reverse sulphating. You need to work out what your total current draw is. If you plan on using a leisure?deep discharge battery say 85Ah and your total draw is 10A then you will get 8.8hrs usage. Note - that would fully discharge, not good, best to run for 5hrs max.

It is also advisable to disconnect the charger during use.
