My EDS died, I suspect my BMS helped killing it by turning it on and off too frequently for too long during the balancing.
My BMS is the EMUS BMS from here: https://www.elektromotus.lt/product-category/emus-bms/ I'm quite happy with it, but required a charger that can be turned on/off other than by just unpluged it, and that lower the current after 80% charging. That is some of the reasons I choose the Elcon which has a on/off input pin, and is programmed exactly for the Nissan Leaf Module I have in my vectrix. The other thing of course is this charger fits into the place of the ESD charger.
So I have choosen the ELCON 1500W charger from here: http://www.elconchargers.com/catalog/item/7344653/7638003.htm I ask for the program 517a with 10 options that allows to go from 38 to 28 Leaf Cells. it cost me nearly 700$: 525$ + 85$ shipment to France + 60$ tax. Not cheap at all, but great charger.
I Attached some pictures of the charger before mounting, and some once mounted. It took me one full week end to mount, was quite cumbersome to find the right approach to attach it inside so the scooter side can still close.
I added some fans, but these will be usefull only at full charge during the hot weather.
If I new about this charger, I would have changed the ESD a long time ago. It is far better with the leaf cells.
Hope this is useful to others!
