Style: 100 AH
Update 4/29/2021 The battery is performing well. We made a trip to Florida to visit my parents which included one night without hookups. The DC to DC charger works great and the battery is not having any issues with performance. I was thinking of adding another but the reply I got was not to do so if the age is greater than 6 months. I guess I need to save for the 200AH model. Update: 6/22/2020 We still have only had short opportunities to use this battery since our trip to Alaska has been pushed back to next year. That was one of the main reasons for purchasing and installing this battery. However, I am still very happy with it. I did have to make some changes though. First, I realized that the tow vehicle could not charge the battery when I noticed that it was lower after towing than before. Two days of towing took it down to about 70%. This prompted me to purchase a Renogy 20A DC to DC charger and to install a battery isolator relay in the Frontier we use along with a dedicated circuit to power it. Now I can be confident of properly charging the battery while towing. Please be aware of this if you purchase one of these or a similar LiFePO4 battery as the 12V circuit running through the trailer connector cable is not suited for proper charging. It would probably be okay for short hauls, but not multi-day trips, especially of one is planning on off-grid camping. I also purchased a 100W Renogy solar suitcase to use if we are off-grid. Between the generator, the tow vehicle, and solar, we have three ways to charge the battery so I think we will be okay for off-grid camping. Original review: I purchased this battery to take the place of two 6V GC2 batteries I have used since December, 2015 in our camping trailer. By specifications, the GC2 batteries have more power, but since they are Lead-Acid, the best practice is to only discharge them no lower than 50% state of charge. The 215AH becomes only 107.5AH. To get that, it meant carrying about 120 lbs on the tongue of the trailer. Comparing specifications, the ExpertPower 100AH LiFePO4 battery can be discharged much deeper without damage, which means that the 100AH is almost completely usable. Also, the LiFePO4 batteries do not build up explosive hydrogen gas which means I could relocate it to inside. The compact size and the fact that the battery weighs only 29.7 lbs means that my useful cargo carrying capacity is now greater than with the Lead-Acid batteries since I save about 90 lbs with the LiFePO4 battery. I had previously built a compartment inside in a place where wires were that was otherwise wasted. This looked to be the ideal spot to put the battery. It had easy access, both to install the battery and to run the wires needed. I also opted to install a battery cut-off switch (relocated from the old battery case) and a battery monitor that will act similar to a fuel gauge in that it monitors amperage in and amperage out and calculates the state of charge. This is needed because a simple voltmeter won't work. The way LiFePO4 batteries discharge is that they have a rather flat discharge profile until they get low. Then voltage drops off rapidly. Beside the battery monitor, I needed to change the converter in my trailer since a lead-acid battery charger requires a different method of charging. We have a WFCO 8955 power center. WFCO makes a replacement converter that has the correct charging profile for LiFEPO4 batteries, WF-8950L2 MBA. One could get by with getting a stand-alone charger and not connecting it to the converter if that suits the installation better, but for us, this was the better option. I also probably could have gotten by with 6 gauge wire, but opted for 4 gauge because of the length of the run from the converter to the battery location. It will keep the voltage from dropping too much through resistance and be that much safer. The specification state that I can expect >2,500 discharge/charge cycles at +20C 0.2C (which I take to be temps between 20C and .2C or 68F and 32.4F) if discharged 100%. If only discharged to 50%, the expected number of cycles increases to around 7,000. Even the lower figure far exceeds the expected life of lead-acid batteries. ExpertPower states an expected 10 year life. Things to watch out for: Operating temperatures for discharge are -4 to 140F and charge 32-140F. Storage is between 32 and 86F. That is another reason for moving the battery inside. I can control the temperatures better when it is inside. Because LiFePO4 batteries have a very low self-discharge rate (approx 3%/month), one can charge the battery, disconnect it, and store it for a year at 77F and not damage the battery. The bult-in Battery Management System serves to protect the battery if conditions go outside safe specifications. I have not had an opportunity to really put this to the test yet as it is winter and we won't be using it much until later this year. However, this seemed the best time to purchase and install it. I will update later after we gain experience with it and I can better report on how it performs.

Style: 100 AH
UPDATED: Zero problems from Sept 2020 until Aug 21. Performed great. Went dead suddenly. 100 AH battery. The only thing different that I did was to hooked it up to my camper from my Test Project. 1-day it turned off. Could not get it to charge. BMP off. I was really stuck in the woods. Had an alternator to charger, nothing. Fast-forward to TODAY. Expert Power told me to use a newer battery charger with "force mode" and this should re-set the BMS. I have a NOCO Genius 10. It has the "force mode". It worked instantly to reset the BMS and started charging. I followed the video from NOCO on this force mode for the Genius 10 on YOUTUBE. Easy. "Poof", worked. My test project was 1x 100 AH of a 400 AH build-out at Year 1 of testing. Now I need to test this battery a bit longer than 1-day back in action, but I feel a lot better now before I bought the 4 x 100s to finish the small cabin build! Lights are on. Good luck everyone! Old review pieces.....I loved this battery (100 AH) out of the box, Sept 2020. Before I bought several, I wanted to test LiFePO4 in my real-life needs. The battery performance was better than expected. RV use and small-shed/camp low demand load uses. Low temp shutoff worked flawless. Charge reasonably. Light weight is awesome. .......This was a 5 star buy until this need-to- have-it work for real and on vacation moment. I even wrote #1 on the battery top with a date because I figured I need many of these and want to see how this one performed as I would record performance with this test purchase. Of course, not even close to the low-end of the life-cycle. Bummer and now pain, never a good outcome with the first try. Good luck with your purchases replacements and builds. I am still a big fan of the lithium option! ....I will posted once more on the outcome with EP on the dead battery.
