I am trying to use an Orion Smart 12/12-18 charger to charge lithium batteries on my travel trailer through the 7-pin charging pin. However, I found out our 2017 Audi Q7 the pin is fused to 15A, so the Orion blows the 15A fuse (I tried a 20A and it does not blow). I like the lithium profile feature and VE.Networking with the Orion and would like to keep it. I thought of placing a 12|12 15A voltage regulator ahead of it. Would that work? Is there another solution?
As a less desirable alternative I could use the Orion 12|12-9 non-smart charger but it does not have a lithium profile. Could I use it in conjunction with a Victron 100|30 MPPT solar controller and wire it in parallel with the rooftop solar panels?
