battery choice
Hi, I am in analysis paralysis. I will be purchasing AGM jars. Here are my two choices: AGM L-16 Surrette 400 amp-hour six volt with 0.145 plates cost $520 plus tax and shipping Four are n...

Pretty sobering stuff about AGMs wanting such high charge currents.
Thanks to all for the links and info.
Need to rethink how best to expand the battery bank of our solar-only system.
AGM batteries do not "want" high charge currents.
...
Our RV 's AGM batteries have seen only low charging currents for years because I do not use a high capacity charger on them ... other than just the engine alternator between campsites. Otherwise they only see 5-20 amps charging currents while camping.
Poorly phrased, sorry, but I see Mex has clarified.
Number of cycles may be of little importance to casual users, but very important to full timers. We're somewhere in between as snow birds. And even though we don't boondock all the time, we move frequently and set up/down uses the batteries (slide, tongue & stab. jacks).
So how many cycles do we realistically need? And even if low current
solar charging reduces the max # for AGM, would AGM still be good enough? Haven't worked out those answers yet.
Currently distracted by the incredible low weights of LFPs.
