Default Lithionics LiFEPO4

So it looks like their batteries keeping getting bigger and better.

What do you think of this in an 8D package? Two or three of them wouldn't be outside the realm of possibility in a robust system.

I think they all will get bigger and cheaper over time. They do now say not to use below freezing, but I didn't see anything about heaters.

They list these as 600 "lithium amp hours" which as I understand it has little to do with a normal amp hour rating, but in the spec document they say it has 600 true amp hours, which is nothing I have ever heard of. I have heard the lithium amp hours are usually more than 20 hour ratings.

Has anyone ever gotten a explanation of that from Lithionics, and how it would relate to the normal 20 hour rate of other batteries.

There is this explanation that I found from another place, but kind of sketchy.

I don't know. Fit RV bought the 400 ah model and that is what they seem to be getting out of it. FWIW, theirs must have some empty space inside as there are various other models in the same case - 450 ah, 480 ah and 600ah

I'm feeling really good about my decision to go with 440Ah AGM this one last time--with the intention to upgrade to Li when they need replacement.
Hope they don't last TOO long.

I'm sorely tempted to get several of these and put in the basement on my new A when it's delivered in November.

Ouch!

The system you linked looks interesting though. I wonder what all that "monitoring system" shows on the LCD display...

[QUOTE=gregmchugh;48276]$9500 for 600AH

GT Series 12 Volt (12V) 600 amp hour Group 8D Lithium Ion Battery for Cars and Trucks, Marine, Recreational Vehicles (RV), Solar Power Systems and Other Applications - Lightweight, Powerful and Safe Lithionics Lithium Ion Batteries.

I'm very reluctant to buy anything from a company that has that kind of website design. Scary.

I think the prices reflect that both Victron and Lithionics main market is high end marine applications where reliability is a key feature desired by the customer.

The Victron system sold by AM Solar includes a battery monitor with shunt and that central color display controller that networks to a whole bunch of Victron units such as their inverters...

Here is the display controller...

How about 10 minutes with a nut driver and build your own lithium pack for half the price?
