From on old thread I found some great info for helping me set up my first powerwall, which I am most grateful for :)

My MPPT charge controller I have set up in 'Gel' mode, as there is no equalisation in that mode, itwants to be programmed for Absorption volts and Absorption time. I have a 7s 70p with average 2000mA /cell

What I am not sure about is what I ought to set the Absorptiontimeto?

[size=small][size=small]It's a Rich Electric SS-50C chargecontroller(which I have used for years with my old lead acid batteries)[/size][/size]

[size=small][size=small]Many thanks for any advice!:)[/size][/size]
 
Set the time to 0. You dont want led acid functionality on lithium. Set float and bulk to basically same voltage. You can diff 0.1v IF needed to top up
