Hi, im working on a powerwall and solar for my autocamper, and im in the configuration fase, but to me it seems that i cannot charge the lithiums up over 31.5V with this one (3.94 - using 8S) per cell, am i correct in assuming this is not possible with this unit?

if its not possible, then i would have to go with 7S for this unit
 
Links to the charge controller you are using would help drastically.
 
You are correct. 7s is better suited for that controller. 24v is not 30+v...

heh, then i guess ill have to create my battery pack from scratch again, lol
trying to make the pack fit in the 2x lead acid battery compartment (672x 18650), so, back to the drawing board :p
 
My apologies. I didn't put the title to the charge controller you're using. I just woke up and haven't eaten or had my coffee yet. I over looked it.

i know all too well, what happens when i have not yet had my morning coffee :) Dont worry about it :)
 
Potentially it should go to 31.5 but i wouldnt. I would stay at 7s to have a basic general setup. 8s on liion isnt really standard
