LiFePo4 - what components required?
Premise: certainly solar is fine but most of my camping is in the shade or in low solar areas so no solar. And there are more no solar reasons too. Intent is to have a battery bank of 4S-8P CALB...

For those who are wondering, LiFePO4 is Lithium Iron Phosphate chemistry. Considerably safer than the "lithium ion" (a generic term, in this instance probably Lithium Cobalt Oxide) batteries we hear about in the news lately, burning up the hoverboards.
But my only experience is with the 3V LiFePO4 cells I use in one of my flashlights. Each cell is charged in its own charger bay. No help for what the OP is doing.
While LiFePO4 batteries "may" consider "safer" they still demand the utmost respect when it comes to charging/discharging current/voltage..
They are still basically fire crackers waiting to go off if you do not follow the rules properly. That is the reason for battery management systems that are critical..
Personally, if you HAVE to ask on a Internet forum for advice on these, you ARE way over your head.
One must ask the question as to why you think you want to go this route..
To save weight?
To save on size per Ahr?
Spend more money?
Or to just sound so cutting edge "cool" when someone asks about your battery system?
Honestly, the weight savings over cost, size, Ahr capacity is just not there.
Two pairs of 6V GC batts will cost $320 and deliver just under 500 Ahr of capacity..
LiFePO4 batteries to get that capacity is going to cost a small fortune, example.. HERE is one for $100, has capacity of.. "Lead-Acid Replacement Range: 10-14(Ah)"
To get the 600 Ahr you desire you would need 60 of these batteries at a whopping $6000!!! Granted there most likely higher capacity examples but I really don't feel like digging any further..
Buy some solar panels, several AGMs and call it a day while pocketing the money you saved by not buying LiFePO4s..
