Hi, I have a Victron MultiPlus (12/500/20 model), and an Ultimatron Lithium battery (it has a integrated BMS). When I connect the Multiplus AC IN to charge the battery, it only charges at 1A or even less than that (battery is at 38%). After some time, it seems to not charge anymore at all (and the "charge" led blinks). I have used the USB MK3 adapter to connect to my computer and configure the multiplus for a lithium battery, but it does not seem to change anything. Do you have any idea on what could be wrong ?
Thanks for your help,
