My 2017 2391 TS (Ford Transit chassis) was built with a Relion RB100 lithium house battery. I was told 100 were produced this way. (so, at least 500, right?)
Itís designed NOT to charge, going down the road, en rout, and it does so perfectly
And is a very obscure and hard to understand thing.IMHO
Without a Victron BMV702 or other decent ammeter
It doesní charge because the Ford alternator voltage is too high!???
It doesnít charge because everything is working exactly as its supposed to?
See what I mean? itís odd. itís not like a missing sink or something
I donít think most people would Ever even notice, or know where to start
The Ďlithiumí BIM inside the Precision Industries Battery Control Center engages (and closes the switch, connecting the house battery to the chassis battery, & charging) between 13.5-14.4 volts. The Ford Transit charges at 14.5. (in other words, it never charges)
The Sterling BB1260 was recommended and tested but doesnít account for the thirstiness of the lithium yet and burns itself up.(as of Jan2018 ver.)
The Victron Buck Boost is my next stab in the dark, more on that later
Iíd like to find at least 5 others, of that alleged Ď100í, to help me sleep at night, or just one other person who has it working somehow and doesnít mind sharing.-)
