I was hoping you would be using an isolator as well as BCDC, I saw this vid.

Then I saw this vid.
https://www.youtube.com/watch?v=ITamN84IiAowhich gives a great explanation of getting the AGM's 'full' and why you need a BCDC especially if you are using a panel with AGM etc.
I started with a AGM ( I think the heat of SA summer got to it ) as the 2nd bat. & now I have been using Lead Acid 2nd and 'refreshing' them when I drag too much out in one session, so I always have lit. banks in the tub if the 2nd lead acid goes bad before we get home.
It looks like they have cracked the re-charging of lithium so a 10 min. charge gives 300kms in elec. car if they raise the temp to 60Deg. while charging this stops the cracking of the neg. post from "plate-like deposits".
But, not that again !!!
It can only ever achieve max. of 80% charge in 10 min.
