Lithium Batteries

"LI in RVs is still in its infant stage. You can buy ready made stuff but it's really expensive. DIY is cheaper but you need to research and be comfortable in what you know."

My take it depends on YOU individually

Remember when you ended up with a better, lower cost computer if you built it yourself? For some of us this stage of Li Battery development is just about the same thing. It's a wonderful time to play with new technology while learning new things. Like a kid with a new toy. A perfect fit for me

Well dammit KJ, if you're gonna play, at least share some blow by blow experiences with these lithium contraptions, in a timely manner.

My biggest concern is how best to recharge them, so as to not do damage, with a solar panel/ charge controller configuration that is OK and plays well with Li technology batteries. Same story, still have the weakest sister and have to balance charge the cells to keep them all in line. Mexwanderer is gonna miss his dipping routine, and it may cut into the sales levels of Freas hydrometers.

All of these batteries, I guess, need to be BCM equipped for dummies like me. Cost of doing business and charging safely.

What do I look forward to the most from these batteries? You can get by with 50 to 60% of previous amp hour capacity in lead acid batteries, and they at that rate will be 1/6th the size and weight for comparable power consumption cycles. So 225 ah T105's will be covered by 120 AH in LiFePo, and probably thats an under 35 to 40 pound battery pack?

These batteries are NOT for the RV park refugees. Heavy hitter dry campers and full timers would tend to benefit the most, not the weekend warrior types. How many folks keep their rig 10 years, the life of these batteries, or 2000 charge cycles? That's 6 years of full time use.
