I wouldn't invest a lot of money on battery reconditioners. You might want to look into first reducing your daily load so the batteries last a little longer as well as researching a new battery system.Comment

The 20 hour capacity is represented in good typography as C20 or occasionally C(20). For the typographically challenged it is sometimes written as C20 or just plain C.
Once you get past that, a number before the C or after the C with a "/" in between should only be used for a rate which is based on whichever C rate you are using for reference. So, as you said, C/10 would be the (twenty hour) C rate divided by ten, and would be a current in amps. And 4C would also be a current in amps which is four times the (twenty hour) C rate.
But some folks write C/20 when they really mean C20, so look carefully at the context.
PS: It is relatively easy to enter subscripts and superscripts when composing a post, just use the x2 or x2 buttons in the formatting bar. If only it were as easy to get ohm and degree symbols. <sigh>SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

It is possible, if the charger output is completely isolated, to hook up as you describe. You can use 2 isolation transformers, if the chargers are not isolated.
You will know if they are not isolated because a dead short will occur when you hook them up. Along with sparks and flames. If you are really lucky, it happens when you first connect. Unlucky - it happens 10 minutes later, after you walk away and the meager insulation slowly fries.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
