I do not have the exact dimensions of the enclosure. Has someone made .dwg out of it?
I would like to figure out if the old enclosure is usable for upgraded pack. Most likely outcome is we will need to make the packs completely and just make sure the connectors and joints fit. The old BMS master unit has to be removed from the old pack and put on the new pack to fool the Leaf. That BMS is not going to do anything with the LiFePO4 pack. I'll make a miniature pack (360V nx100 mAh) which that BMS will be measuring. DC/DC between the LiFePO4 and LMO packs will keep them on identical SOC so the Leaf BMS is fooled to think all is as nothing has happened. This is my $50 hack to go around the BMS problem. :) -Jukka 2017-01-20 2:46 GMT+02:00 Cor van de Water via EV <[email protected]>: > Hi Jukka, > > I will hang on to the shells, they have been in my yard a few months > already, I can wait a few more weeks ;-) > > Do you have the outline of the box?
