I just bought the POWMR ALL IN ONE 3 K HYBRID INVERTER/CHARGER/CHARGE CONTROLLER being sold under $300 on the bay. They are old stock, said to be for" lead acid only". BUT it is 24 volt dc . An, 8s, 24 volt, lifepo4 has the same charge needs. it's perfect for $268 plus a $40 wifi module. I think it will do fine.

Hey mate, sounds pretty solid. Let me know how it goes!

[@chappychapman3480]

Out N About, You're pretty much come to the conclusion I'd come to but I've got something you might like to test, first I'll give you an idea of my setup, 2 iTech 120X lithium's, 500w solar, Victron 100/50 solar controller with a Victron 500a/h shunt, Projecta 25A charger, and a Vitrifrigo 150Lt compressor fridge, what I've found with the Setec that I've still got connected (I have my Victron Shunt between the battery and the Setec shunt) is it charges at a higher rate when the batteries are down a bit but once they get into the 13V range it slows down, it also has a Max voltage of 13.8 and a float level of 13.5-6, once on float level it has a trickle input of .8A, but the big thing I've found is when my fridge kicks in it doesn't replace the outgoing amps about 5 to 6 when running and just trickles along, if I'm on 240V overnight when I wake in the morning my SOC will be down to around 90% depending on time of year and how hot it is, the Setec doesn't seem to have the ability to recognise the outgoing Amps and replace them when it's on float, it just trickles along, I don't know but maybe it has to get down to a certain voltage before it kicks in and starts replacing the outgoing amps, it doesn't bother me that much because my solar will soon replace the amps in the morning, I know iTech says you can drop their batteries in and they're compatible with most setups but I don't like to leave my Projecta charger on overnight because it has an unchangeable float level of 13.8 and my Solar Regulator, Shunt, and Setec are all set at 13.5 so if I ever need my charger which isn't very often as soon as it reaches 14.4 it only takes about 10 minutes to go through absorption and to the 13.8V float level and when that happens I turn it off and I never leave it on overnight. My opinion of the Setec BMS is it was adequate for small systems back in the 90's and early 2000's but Jayco should have invested in a different system sooner than they did. Cheers PS. Maybe it's just my Setec. Lol, but I don't think so.

Is that a heater in with your charger /inverter? Keep an eye on the temp in there.

[@donaldo1974]

Mine will charge my renogy lithium to around 98% but the charging slows due to the agm profile towards the end, I do have a victron 17amp smart charger and have run both at the same time for a faster charge

[@OutNAboutAustralia]

I found the same mate. Tops out at about 98 then struggles to go any higher

[@immrnoidall]

@@OutNAboutAustralia You can adjust the the float charge higher.I don't know why that works , but the regular bulk charge don't. But I find that even if you charge that lifepo4 to max. it will still settle to 27 in short time anyway.. I think the lead chargers might govern by resistance or something lifepo4 lacks.
