Pecron E3600LFP grid down testing wrap-up.

[@cuddebackfamily9479]

Hey man, I love the videos and the shorts and I subscribed to your channel. I’m thinking about buying this unit and the expansion battery so any video you put out I’ll definitely be watching.

[@hickshomestead113]

Thanks for subscribing! In the next month or so, I will be setting it up at my new homestead to run my RV. I will also be adding 4130W of solar panels. I haven't seen anyone actually do it.

So 1st thing, don’t be afraid to cycle your batteries from 100% to 0% lipo4 is not like nmc or other lithium. Secondly always charge to 100% to balance all your cells. I have the same set up in the same battery configuration, and your main unit will not hit zero and turn off, it will stay on until all batteries are zero and then turn off and that is one cycle for all batteries. I used this battery bank off grid all summer in my RV with 2000 watts of solar and it never got below 50%. I also have 4 portable 400 watt panels that I can plug directly into the batteries and they are only 47 volts open circuit so no problem bringing in solar 2 the extra batteries. I never had to use them. 2000 watts into main unit on my 30amp trailer was fine. Hope this helps.

Watch Will Prowse recent video on these lifepo4 batterys. You don't need to do the 80 20 thing. He says they will not balance if you don't bring them to 100%. Since you are going to store these 50% is ideal for storage. Food for thought.

Completely AGREE!!! ❤❤❤

I think his strongest point there was you paid for 100% of your battery. Worrying about maintaining that 100% at the expense of not using a significant portion is like the proverbial body found in desert with a half full canteen.

[@johnmal5975]

@@Senthiuz Agreed! It's like the kid who gets a football for xmas but doesn't want to get it dirty. I think his other point was these are not lead acid battery's so stop using them like they are.

Hey thanks for the video, I have the Pecron E3600LFP, and will receive my EP3000 Extra battery tomorrow so I do not have much experience with extra batteries yet, but I have done alot of research from others that do have them, you should check out Ramblin Bob's channel he has the entire system like you do and tests extensively, I have learned alot from his channel alone, check it out if you like, one thing you should do is charge all your batteries 100% it wont hurt this type of batteries but they balance out, just set it to charge at 100% and leave it charging a day or two and keep checking your battery health and you will start to see the volt numbers increase on each cell and you will also see each cell start to balance out, again the system does this all automatically for you just set it to 100% charge. keep them videos coming and stay strong and encouraged!

[@timmccall8318]

I don’t have any expansion batteries yet but I can confirm that my e3600lfp top balances at 100% If I were you I would fully charge the entire stack until current draw has dropped to zero and stayed there to fully balance all cells then repeat the test, at least partially, discharging to 50ish% for your storage, depending on how long that will be. With the flat discharge curve of lfp and the cells likely not balanced, the main unit is probably not getting a completely accurate picture of the expansion batteries state. As another commenter said, watch the latest videos from Will Prowse about cycling lfp batteries for solar.

[@Deagle367]

Mine never goes to 100%. It hit 99% with 1 minute of charge time left but just stays there and never hits 100%. I remember waiting like 8 minutes at 99% charging at 1800 watts. It got to 55.2 volts on the batteries.

[@Vetteman40th]

Disconnect the host from the expansion batteries and charge to expansion battery level then charge everything together to balance.

[@thetravelingmyfundsarelow1693]

It could be the inverter draw on the main unit. I have the same unit with 4 batteries and love it! I use it in my rv. Mine does the same as yours so that’s what I think. Anyway keep the vids coming 👍🏻🇺🇸

[@rod2625]

Any luck in finding the Pecron recommended cabling sequence? Will order the 3600 and (3) 3000 batteries this week. I am also exploring the best manual transfer switch for these units. Again not much info available. Currently thinking between a 6-10 circuit transfer switch.

[@busterhyman6633]

For 5300 I will want to use more than 60% of the capability. I might get myself one of these I like how fast I can charge it from a 30 amp generator. They have their place and the price just keeps coming down which is great.

[@ChrisEpler]

Charge to 100%, they aren't lithium ion, LiFePo4 will handle being at 100 just fine esp if it's in a situation where you need to have the power available. As for cycles and life, you'll probably lose more in shelf life over 10 years than you'll lose from cycling them. Not sure how Pecron does their balancing but likely a passive balancer that burns power off cells that are high when it gets to a full charge. LiFePo4 charge curve is VERY flat, looking at voltages for how full something is won't work out very well. Set your charge limit to 100%, charge up and check cell balance after a day or two. Wonder if they give any balancing status info, that'd be nice to know.

[@oneisnone7350]

Hmm, I only have the E3600 and a single EP3000. And they stay much more close together. I wonder if you had them connected more sequentially if it would make a difference, like 1 connected to 2, 2 to 3 and 3 to 4….

[@bobmarshall4143]

I like your videos and this test. Keep up the great postings! I also purchased the e36000 plus 1 expansion battery which is currently in shipment. This after we had a power outage of 59 hrs. and had to throw out most of our stuff. I Decided to go this route instead of a generator. I think you said you have no solar yet; I do not. And again no generator. I am curious as to how you charged your ep3000 batteries? For me 30 hours using the car or truck battery is of course too impractical. But, I have heard it's best to charge the host battery to 100% set it aside. Then charge the expansion battery to 100% before putting them together. This was a video I saw on Amazon reviews and it was the Pecron e2000 which comes with the (brick) charging system. He also claimed it was important (recalibrating) * my term; the Host e2000. I don't want to degrade my new generator/ batteries out of the gate after I get them. Anyone reading this if I charge both e3600 and ep3000 together at the same time after receiving them will that do either unit harm? degrade is what I mean
