My new MultiPlus 3000 12 120 seems to charge my Lithium batteries just fine, stays in bulk for a while with charge current close to max, then to absorption with charge current still fairly high. This is the same for no VE.Bus connected or the MK3-USB connected.
My issue is that when I connect my new Smart dongle, it does a super short bulk < 1 min, and absorption goes to less than 5 amps, so charging takes forever.
I have not seen anything on this, am I missing a setting, I have checked connections, changed cables, I am at a loss? Is it possible I have a bad dongle?
Thanks for your help, Brian
