No problem, glad you found the thread useful!
My setup has been working really well and I have basically not touched it at all. I have winched a lot (combined), and run the spare battery down a bunch and it always performs well.
I never really touch it.
The only annoying thing is that the National Luna Charge display almost always shows an overcharge condition and beeps at me. I have to cancel the beeping a lot. I understand this is a common problem from looking around a bit online. Seems like their set point for the alarm is a bit low.
I have noticed that the 300A VSR's are hard to find. I guess I lucked out that I found that one on ebay...
