24v lifepo4 100ah or 200ah battery

[nailer]

What would be everyone's choice on 24v?
Currently running 2 12v lifepo4 in series.
But would like to start to upgrade to 24v batteries

Confused? Why would there be a choice between 100ah and 200ah. Bigger is always better, but without knowing the application...........

Your usage would have some bearings on what to do
If your loads are light a single 24v battery may be adequate (and as stated above - bigger is better - having extra capacity is always nice)
If you're going to have large loads with high amp draws from the battery then (2) 24v batteries in parallel would be better than a single

For example:
a 3000w load will require 125+ amps from a 24v battery
Most batteries are limited to 100a (some more, some less)
(2) 24v batteries in parallel will share the load so only 75a is pulled from each
If a single battery is close to running most of the time at or near the BMS limit then it's better to have a parallel set as to not overwork a single battery (heat takes a toll)

I should have told more this system is at my off grid cabin.
I am looking for what brand of battery is doing best right now.
I plan to put multiple batteries in parallel.
I should have made my question more clear. My bad
Thanks
