A few notes. Without diode isolation the power supply leds come on when connected to the pack. They also come on when plugged in in. At most they are slightly warm to the touch at the current levels mentioned. the set voltages of these supplies is also very stable without any fluctuation.
I haven't set up a final charger yet as I'm waiting for the led driver / 300mA current limiters to come in. The battery I am playing with is the battery from the car we picked up from RHDInsight. That battery appears to be less than a few years old and is testing at full capacity. It even has the yellow shrinkwrap on the subpacks. I'm pretty sure it had been replaced under warranty.

Please post or send me instructions how to build one , i am in dire need of a grid charger (cannot believe that honda is not selling one at least as an accessory)
seems my driving style does not allow enough charging so every couple of days the battery starts recalls and forced charging which hurt my mileage.
I found one solution where I drive in third up to 85 mph, then coast till it falls to 60 (charging the battery a little ) then accelerate in third gear back to 85 and so on for 25 miles (my commute home) the mpg suffers but the battery is charged...
So instead of creating havoc on the road I would rather charge the battery at home every couple of days if I could
I am not much experienced, but have some basic electrical /electronic knowledge and can follow instructions if details are well covered.
I have a set of the ebay Meanwells and can get the other needed parts online.
thank you
