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.

I was looking to replace a 200 aH AGM battery for a 1/3 HP basement sump pump that had failed after 12 years. AGM batteries can only run down to 50% of capacity so you really get 100 aH of useable run time. In researching replacements, I came across these LiFePO4 batteries that are much lighter (30 lbs vs. 130 lbs) and therefore much easier to handle. They also theoretically can run down to 10% of capacity. I looked at several brands and ExpertPower seemed to have the best combination of price, support and user reviews. Battleborn had higher ratings but were 25% - 30% more expensive although they have a 10 year warranty vs. the 1 year for ExpertPower. I figured like with most electronic products, problems are likely to occur in the first year. When I received the battery and corresponding charger from ExpertPower, the battery was shipped with only 50% charge. It took a while to fully charge up (3 - 4 hours) and I contacted ExpertPower after 2 hours of charging to see if it was normal to take this long to charge. They responded right away and I spoke to someone who explained the charge process and was very knowledgeable. The battery charged up fully after that and then I did a capacity test by connecting a 100W incandescent bulb. The theoretical capacity of the battery based on 90% usable capacity and 90% inverter efficiency is 100 aH X 12 V X 0.9 capacity * 0.9 Inverter efficiency / 100 W = 9.72 hours. I roughly timed mine at 9.5 hours which was inline. I then hooked it up to my sump pump and the inverter ran the pump a few cycles with no issues. I had to modify my inverter (Tripp Lite APS1250) to disable it's charging circuit because the charging profile for these batteries is different from AGM or Wet Cell - you might reduce useful life or damage them with the wrong charging profile. Also, ExpertPower said the self discharge rate is very low so if I don't have a power failure and run the pump often on battery, I should not leave their charger always connected and only recharge or top up the battery every 3 - 6 months (or perhaps before a forecasted storm event). Based on the price and tech support, I highly recommend this product. I have only had the unit for a week now and will update this after some time has passed, or I have gone through a prolonged power failure that resulted in my sump pump running on this battery for an extended period. Currently, if you register the product within 30 days, ExpertPower will extend the warranty to 2 years total

The media could not be loaded. Well, I reviewed a lot of batteries, and this one is the worst of them all. I bought this battery a while ago but didn't have time to test it. I charged the battery according to the specifications with a Victron charger and connected my meter without any load and as you can see the voltage dropped from 9V to 8.57V in just a few seconds. You’d think that the Undervoltage Protection should prevent the battery from going below 10.6V but it wasn't the case here. I tried contacting their customer service via the form provided by Amazon and got no response. I then sent them an email. They responded and asked me to provide some evidence. In the next email, they asked me to provide them with my shipping address. And only after that, they told me that I have to pay for the return. They claim you have a “10 years lifetime warranty” but you’ll have to send your defective battery back. This battery is highly overpriced. You can get 6 or 7Ah batteries from other brands for half-price. If I pay for the shipping the total cost of this battery will be enough to buy 20Ah from Chins. I don't know about you, but I will never buy anything from this company ever again. I refused to pay for the shipping and now I am stuck with a dead battery.

Great little battery. Using it to power an FT-817ND amateur radio. It holds up for several days of active use. No problems with the battery at all to date. Good price and a good product. My bigger battery ran out for my FT-891 and this little battery stepped in for a while at 100w and lasted for over an hour, so it definitely punches well above its weight.
