Extra Battery 3840Wh, Expand Capacity for E3600LFP/E3800LFP/F3000LFP/E2400LFP/E1500LFP/E1000LFP, LiFePO4 Backup Battery

It is a great battery for the price. It doubles the run time for my Pecron F3000LP. I like the fact that it can be charged independently via solar panels and the usb and car ports gives access to the battery's power without an inverter or additional unit. This gives me the option of using it independent of the main unit.

So far all is good! The expansion battery doubled my energy capacity allowing me to run portable AC in my weekend cabin. I normally only need power for two days, these are working great for my needs. When initially connecting to main unit it took almost 2 hours to be recognized… main unit was at 80% charge while expansion read 75%. The length of time needed to sync was longer than I expected. When charging through solar it is taking longer to charge battery now, this is due to both batteries now being charged. I will need to monitor and recalculate my solar charging expectation.

Pecron Expansion Battery and E3600 Host is a great backup power source!

I have bought 2 Delta 2 Max (Eco Flow Units) and I wish I could have come across this Pecron E3600 LFP before I had bought those two Eco Flows, My Pecron E3600 LFP is One Thousand times better than the Eco flow's Delta 2 Max, more power going out and more solar power allowed to charge them, I have 2 slots where I can use 1200 watts of solar power coming in on each slot, Eco flow only allows a mere 500watts per slot and has 2 slots, Pecron is powering the entire house, with no issues since we can use the power of the sun to charge them all day and all that power can be stored and used at night also, do yourself a favor and get a Pecron EP3600 with these EP3000 Extended batteries, you will be glad you did!

Very good price, it can be used by itself to output DC and USB power. It can also be charged with solar.

Work great! Nicely made, very useful in many ways.

This extra battery is very versatile and has a lot of power.

I purchased the 1000flp and it was delivered July 31. Seemed to work ok and I bought the expansion battery which was delivered August 30. Both seemed to work well. Today my power was out in the living room and i realized my circuit breaker tripped. Reset it and everything worked but there was a faint beeping noise somewhere which I eventually realized was the Pecron unit. The little alarm bell icon was blinking but I couldn’t figure out how to determine what the problem is. I couldn’t find anything in the manual about this. I finally found the little bell in the app and clicked on it and saw two error messages - Inverter output overload and power pack over voltage. I couldn’t find explanation of any of these errors in the app or in the manual. When i plugged the pecron 1000 back in the AC I heard a loud pop and I quickly unplugged it. I’m worried it will trip a breaker or worse become a fire hazard. I have yet to hear from Pecron Support. These items are not returnable. When I first tried leaving a review, I had trouble finding this unit on Amazon and then realized what may have occurred. I clicked on my original purchase and found the unit with a negative review and THAT unit is no longer available for purchase. Then I found another listing for the same pecron 1000 unit which is active and of course only has a positive review. So I guess if they get negative reviews they disable one listing and just start another one. The original listing that I purchased my unit with had only positive reviews when I bought it. So in summary, it appears I am out at least $1400 for these two units that I refuse to use because I’m terrified that they will cause problems in the rest of my home or fire hazards. What’s worse is they have an app for these units which I have notifications turned on, but the app does nothing to provide notifications that there are alerts that need attention. What’s the point in having alerts if you physically need to be in front of the unit to either hear the alarm or see the screen? I purchased these units for reliable backup, especially when I’m away. I need to have some minor surgery and will be unable to lift these units even if I was able to return them. What a waste of money.
