1. You cannot mix Lithium with other type batteries, if that is what you were going to do
2. When you install Lithium batteries in a system that did not have Lithium's originally, you need to verify your RV Coach charge system(Converter or Inverter/Charger) is compatible with charging Lithium batteries. If not, then you have to either change the Charging system parameters(programming) if your existing system can be changed, or you have to replace the existing Converter or Inverter/Charger to one that can charge Lithium's correctly.
3. Otherwise you will have spent a lot of money for Lithium's for nothing when they go bad. Lithium Warranty is NOT like Lead Cell battery warranty's. The batteries are so good that the only way they fail is if the Customer did not maintain(charge) correctly. They will actually tell that if you try to get them replaced under warranty. Doug

Lithium label amp hours ex 100
Subtract 10 amp hours from upper end not useable ?
Subtract 10 amp hours from bottom end not useable ?
80 useable amp hours?

I've read enough to develop questions I can't seem to find the answers to, so I'm here once more to soak it in.

I've had some concerns that the current and original batteries on my Class A might need replacement, even though they're about 3 years old, in part due to my lack of experience in depleting voltage to a point that running off the batteries inevitably runs out of power in the wee hours, with the meters showing me LOW VOLTAGE somewhere in the 11's, so, I'm considering Lithium.

I also have 480 watts of Zamp solar, maxxed out at 26.1 Amps, along with a separate portable 120 watt panel, and a Zamp Solar 30A Controller. Am considering adding another panel or two -if I can find a place to mount them, and realize I'd need a new Controller, maybe 45-60 Amps, MPPT, and should be more than sufficient.

Having recently retired, I now have time for some extended travel, and boondocking will almost certainly be a part of that. I'm looking forward to getting off grid periodically, so power resources are key.

I'm aware of the cost, and believe that this is the most economical long-term approach to my power systems. So I'm willing to consider Lithium, and need some answers to fill in a few holes...

My rig came with 4-6V batteries, each 115 min at 75 Amps, 220 [email protected] 20Hr.

If I connect Lithium in parallel, do I double available amps?

Are Lithium's all 12V, and if so, would I need only two to replace what I currently have?

What changes, if any, must I make to existing systems in order to accommodate Lithium batteries?


You might want to look into these 12V Group 27 silicon dioxide RV batteries instead. They're about 1/2 the cost of lithium and in my opinion are superior to lithium for RV use:

Like any other battery they should be stored at 100% SOC, but do NOT require any trickle charging, even when stored for months.


Actually, you don't want to store them at 100%. This will actually damage them long term.

50% is ideal but 80-90% is far enough from 100% that it addresses most of the concern.

I have to give credit for me learning of these great (I think, so far) RV batteries to this poster -> "pianotuna"

Here's the link where I first learned of them from him:

What is wrong w/ lead acid. If I had money to burn, I would still buy lead acid !

mchero,

Here is some more information:

"Shari from Azimuth to answer your questions... The ones above are manufactured in China by a Canadian company, Soneil Electronics. Soneil has been around since 1994, but they made smaller size light traction SiO2 batteries for the healthcare and materials handling industries. It wasn't until a few years ago that they expanded into larger size deep cycle solar. RV, telecom and marine sizes. They haven't been that great at marketing so they are a best kept secret. Lead crystal / SiO2 batteries are currently being made by Betta Batteries(Australia), Green Rhino (Germany) and Soneil Electronics (Canada). I have attached some studies of lead crystal / SiO2 batteries for review. [emoticon] So far, all the ones in the field are exceeding our expectations."

Would it make sense to replace my four 6-Volt batteries with 3 Li, assuming boondocking would become my primary activity? Two would seem sufficient for routine camping needs, but if I'm off-grid, I like to have plenty of back up, should it be needed...
