Lithium -LiFePO4 - House Batteries

[IMSAGTP]

We decided to try the Renogy LiFe 100A batteries. We've been using Lithiums for several years on E-Trikes, one LiFe pack has about 500+ charge cycles now and still retains 94% of its rated power. Not bad.

Who else has experience with LiFe batteries? Can you share any experiences with them?

Our 2016 Thor Siesta was delivered new with 2 lead-acids with a stated rating of 160 AH. They didn't seem to last long. Water level is good, and electolyte density is good.

Pulled them out and weighed them. Lead-acid on the best day has a power density of 15WH/Lb. At 49Lbs, the physical limit of these batteries is 60AH. The desert heat here probably destroyed the plates.

These batteries have an internal BMS and the house charger provides an optimal charge condition including float. We're adding a 300W solar kit as well with a Lithium charge configuration, along with 2 storage current meters to measure IN/OUT to the batteries.

Anyone else running Lithium?

Going on 2 1/2 years of fulltime living off of 1,280w solar & 500ah Lifepo4 batteries on the 5th wheel. Charging has been set at 14.1 bulk (CC), 14.2 absorb (CV)(10 minute is minimum, can't be turned off), float 13.6 (CV) since day one (30 months ago) with no issues, the system has not been turned off since. Figuring at least 870+ 30% cycles. With some periods of time totaling 70% DOD after many consecutive days of rain/ overcast.
During these 30 months generator was used roughly dozen times for 2 hour each time putting a 200ah hold over charge into the batteries.
Total weight of the "entire" system 500#.
