I will do my research of course to compare, hard to find these videos. I recently had a LifePO4 fry after only six months of casual use, not sure why but it was under warranty and being replaced. I set up my 6x100 solar panels and three pairs of series then paralleled them to my Renogy Rover 60 amp charge controller.
The guy who wrote the 'marine lifepo4' article makes a pretty strong case for a 13.6V float charge, as well as Will Prowse recommending it for Battle Born. For my personal (not renogy) setup I'll be going with 13.6.
One_Mega_Ohm can only say my batteries are still set with these settings and performing well. I do like Will Prowse, I’d trust his settings too. What brand did you end up going with?
@@boristheboxvan8485 No fault in using the manufacturers recommendation. I just thought I'd chime in with another option to look into for anyone checking out this video. I have a set of the blue Chinese 280aH cells. I don't have them fully setup, but I think I'll be going with a 14-14.2 charge voltage and I might even go lower than 13.6 for float. I'd rather go for longevity as opposed to capacity as I should have plenty with 280aH for now.
13.6V at float (which is basicly the 'maintenance' voltage) should be fine for frequently, heavily used batteries with loads like a refridgerator on it at a daily base. for slower drains like a constant on-grid feed/inverter 13.4V should be fine. keeping the lifepo on a constant charge at 14.4V (because that is what happens when you let them 'float' at this voltage vs. just boosting them shortly) means stress for the cells, which will shorten your overall cycles in the end 🤷🏻
i did not use lifepo4 but i was using 18650 and had the problem of the bms shutting off and controller could not kick in to turn it back on what i ended up doing was adding a buck converter from solar input to the controllers battery output so it would charge the battery enogth to get to the turn on stage of the bms and then the controller could take over
Unless you have somewhere to switch off temperature adjustment. Surely you need to set the temperature adjustment to 0mV /°C per 2v. Ok yours will probably be Fahrenheit but it will still be zero. This is difference in temperature from 25°C. Remember this figure is multiplied by 6 for a 12v battery. This function also reduces the charging voltage settings above 25°C. Also you left the charge limit voltage set to 15. The above formula takes the voltage above this and it is provided to prevent damage to connected equipment. 15 v divided by 4 is 3.75v. This is above the maximum charging voltage of LPO4 cells so you are likely to damage your battery in cold conditions. Probably somewhere between 14.4 (3.6v/cell) and 14.3(3.5v/cell) would be more appropriate. Note it may be that not fitting a temp sensor will inactivate the temp correction but some switch to temp at controller. However I would prefer to see it set to zero. You might want to Email the manufacturer again just to make sure. I say email as that gives you evidence of what was said. Best wishes
Hallo Ich verstehe leider kein Englisch 😔 sind das die richtigen Einstellungen für einen MPPT Laderegler ,im Zusammenhang mit einem Lifepo4 Akku? Ich habe nämlich einen EPever 2010An Trace,und als Akku habe ich eine Lifepo4 / 176AH, das alles wird mit 12V Betrieben. Nur weiß ich leider nicht,welche Einstellungen ich in dem EPever machen muss,das dieser auch gut mit dem Lifepo4 Akku arbeitet. Lieben Dank erstmal. Grüße, Jürgen
Great video . I am setting up a 100 amp mppt charger controller i have a question i cant find anything on . On battery amps per hour is that total of battery bank or the type i am using 100 ah battery 5 of them . I set it for 200ah having 2 100 ah batteries in bank right now. My fear was cooking them lol. Thanks again great video .
charles foster no problem. You will set it to your total accumulated ah. So if you have 2, 100 ah batteries like I do, then you set the MPPT controller to 200ah. That also is dependent on if you hook them up in series or parallel. One will double the ah, the other will double the voltage and leave ah the same
I just bought a renorgy 100w kit that came with a wanderer charge controller. I've also ordered a Iccnexenergy lifep04 battery. It's not clear to me if I have the right charge controller for my battery, the wanderer doesn't list lifep04 as a battery type it charges. Do I need a lifep04 specific charge controller?
According to Renogy’s website the wanderer is compatible with LiFePO4. There should be a profile setup for it that you can access through programming it. I think all Renogy instructions are on their website or you can call them I’ve had good luck with customer support
Thank you! I just got a BT-1 module and working through the settings now. Watching my charge controller via the BT-1 it shows 100% charged but also shows the battery absorbing 2.4A from the panel. Will the charge controller automatically turn off the charging current to the battery when it is fully charged? I bought the battery used and advertised as "tested to have 94% capacity remaining" and am also wondering if the battery will ever trigger the charge controller to stop sending current since it can't reach a 100% capacity?
Thanks this helped me set up my ROVER LOL! It's such BS that they would tell you that you need a rover, the app is awful and the settings are for LI ION! What a joke!
I would not trust Renogy's advice on controller set up. I have 2 Renogy 170Ah Lithium batteries with Epever controllers and I would never use the settings you just quoted. Sorry but in time your batteries will suffer damage.

Why can't you put these batteries in series?

Just horrid. Renogy doesn't understand Lithium...
