If you can see the individual plates by looking through the E/lyte hole, that means the plates don't even have staggered holes for E/lyte and gas. Huge current loss = heat= low actual production. 3 bi-polar plates per stack isn't making much hho, it's mostly steam caused by hitting each individual cell with an insane 3.45 volts. This is why we all use a minimum of 5 bi-polars, I've never used less than 6 myself (1.97volts per cell).
