Regardless of price, can you just drop in a LION battery as a replacement for lead acid and not worry about the charging circuit and technology?

I also dabble a bit with Radio Control cars and planes. Several years ago when LION became available in RC it required a lot of changes. New chargers that you could set the charge current in relationship to battery capacitance as well as have a second monitoring circuit to manage the charge current in relationship to the state of charge. If one was to use the old NiCd or NIMH chargers on LION you were very likely to have a battery explosion and fire. In fact it is still common to use flame retardant battey pouches to keep LION batteries in while charging in case there is an issue.

LION is a superior battery chemistry, but it can be volatile if not used properly. Maybe the current multi-stage smart chargers in modern RV converters provide this protection if you change to LION -- but I would really want to do some research before I replaced my lead acid batteries with any other chemistry.

Read - A Year On Lithium

Here is an article regarding Lithium and an RV. They follow up after a year of use.

http://www.technomadia.com/2012/09/a...-rv-batteries/

You will need to make some charging adjustments, also probably best to buy Battery Management System designed specifically for Lithium batteries.

Still have to charge them....

I will wait another year or two....
Just my thoughts,

Don

Well I just checked this out. It looks pretty kool. This is the 5300 version I might get the 6000 version of this and put it in my generator box. Check out the video!

http://totalsolar.us/

This is a 24 volt system.

Let me know what you guys think!

Not that I know of.

Keep in mind that the difference between 60% and 50% charged is only .14 volts. Hardware would have to be very sensitive and big $$$$ to be accurate I think.

That said, I'm sure that the inverter itself has a shutoff point of its own, but by then you could be down in the 11 volt range. Well below the level that you ever really want to take your batteries

Both mustang65 and I have some schematics and pics of our power systems with Solar in our profile sections. You can get some build ideas if you like.

Thanks I'll check it out. Here is what I have in mind thus far and yes it's expensive. Now remember I live in my 5er full time........

This is a 24 volt solar system!

Solar Panels:

I can get 4 of these Mono panels on my roof:

Sise: 64"X40" Weight 37lbs each 300 watts each for a total 1200 watts.

http://www.lg.com/us/commercial/sola...lg-LG300N1C-B3
================================================== ====================

Batteries:

4 - 460 AH each Rolls Maint. Free batteries 10 year warrantee. 1840 amp AH total

http://www.dcbattery.com/rollssurretteagm_s6-460agm.pdf

================================================== =========

6000 watt 24 volt power inverter:

http://www.aimscorp.net/6000-Watt-Pu...r-24-Volt.html

================================================== ==========

Solar Controller:

http://www.ecodirect.com/Xantrex-865...mppt60-150.htm

================================================== ==========

Since I have no Generator in my Generator bay is empty and has the wiring and Transfer box already installed this is where I'm going to put all the solar stuff in there.

Plus I gotta buy cables and Thats it!

So let me know what you think.

Voltage adds in series strings, amperage adds in parallel strings

4 - 6VDC 460Ah batteries in series = 24VDC @ 460Ah

now

split that up into (2) 12VDC strings and you will have

12VDC @ 920Ah

I would go with the 2 12VDC strings...

Just my thoughts,
Don

Humm... Did not know that I'll have to go and check that out. So how would you go and set that up and with what hardware.

Thanks Bud
