Hi Wallace, not sure whether you have Tiffin installed solar, whose controller you have etc.... I have the same battery booster and have retained it. I talked to Battle Born concerning there LIBM equipment and basically the said without it you could reduce the cycles from 5000 to maybe 3000. If you have the GP Electric controller they have just released one for lithium batteries.
All in all, I purchased:
2-Battle Born batteries
Progressive Dynamics lithium converter
GP Electric lithium controller
Hope this helps, I'm sure Mark can be more helpful.
BTW, I am quite happy with the upgrade (so far).
