Hi John @john p , It has been a few years so hopefully you are still on the forum. I read your injection specs and results with great interest and thanks.
My one question is: where did you put the two air injections tubes in each cell? The commercial systems use a single tucked in one corner from what i have seen, but you state clearly two were needed for uniform circulation!?
Does anyone else know where John put his two injector tubes to achieve circulation uniformity?
I want to fit my new 48V bank of RV batteries with air injection to compare life with my existing set of identical batteries to check out air lift circulation for myself (and maybe get a life extension to offset the effort). They are stationary (float charging from the mains) most of the time.
