The new charger is exactly like the six others, except this blue sticker instead of orange
Only now I decided to open the problem charger, and discovered that its fan connector was simply not plugged into the charger PCB ... This was easy to fix ! :-)
I then replugged it the the ESS Control Board / EMS to test it and the fan started spinning right away :-)
Now, let's prepare this new charger to connect it with the other ones:
Always the same thing: remove the original US AC plug, strip the wires and apply solder to make it stronger; On the DC side, remove the plug, strip the wires and solder 8mm lug on positive and 6mm lug for negative
Done !
So I now have 7 Low Power Chargers to feed my battery pack, and had to plug 2 on the same AC port, together pushing 650W
The stack is getting a bit high with 7 chargers !
2 chargers are connected to the same AC port
7 x 92W = 650W (roughly)
It is tight, but all the DC chargers cables fit
This is the new charger positive lug
and the negative one
