After 4600 miles on the road, I can report that the li-bim (precision circuits inc) works every bit as advertised. Longest stays 84 hours, lowest DoD 24%. Alt charge max 58A or variable, 0A charge at 14.2V. The Li-BIM is an easy change over from LA to Lithium and the chassis/coach battery charging functions as designed, an alternative to DC-DC charging. I do not know the algorithm of the device, however I never noticed any alternator overload or overheating. BTW the 200a LFP battery was only recharged with alternator or solar for the entire trip, no charger

I believe it’s 15 min charging and 15 minutes off. We’ve had good luck so far also. Only issue is I think the wire they said not to connect might have something to do with our rear door locks. I may need to wire it in to make the locks work correctly.
