These seem to be decent batteries for the money. However, there are a few things to be aware of that are not adequately covered in the documentation that comes with the battery. The supplied 14 mm M8 terminal bolts are too long for some applications. Depending upon the thickness of the battery lugs, it may not be possible to fully tighten the bolts before they bottom-out thus leaving the lugs loose. This might go unnoticed but it is important to ensure a tight connection to avoid sparking and arcing, especially under heavy loads. To fix this, replace the supplied bolts with 12 mm or 13 mm long bolts or add a washer or two to take up the slack if you want to continue with the original ones. If using washers, be sure to place them above the cable lug so that so that it remains in direct contact with the battery terminal rather than forcing the current to flow through the washer. The manufacturer’s specifications provide that a resting voltage of 13.46 volts indicates a 100% state of charge (SOC). The battery voltage is significantly lower when received because transportation safety regulations prohibit the shipment of fully charged lithium batteries. Before use, be sure to charged the battery with a charger specifically designed for LiFePo4 batteries. While some chargers come with traditional battery clamps, it is much better to hard wire the charger using correctly-sized lugs or ring terminals. I chose a 14.6 volt 20 amp charger that came with ring terminals and Anderson connectors that permit it to be easily connected and disconnected from the battery. Note that the battery manual also cautions against clipping charger clamps directly to the battery bolts and specifies the use of copper terminals to clip the charge clamps to. This is due to the small contact area provided by the jaws of the clamp. Hard wiring the charger connections avoids this issue completely. The charger I bought also has an automatic “wake up” or “repair” function for situations where the Battery Management System (BMS) has put the battery to sleep to protect it from excessive discharge. I found this to be very useful. Unlike traditional lead-acid batteries, the cells in LiFePo4 batteries like this one are not directly connected to the external battery terminals/posts. Instead there is an internal Battery Management System that controls both charging and discharging. It includes a low-voltage cut-off that internally disconnects the output of the battery from the battery terminals if it is discharged below a predetermined voltage -- about 10 volts for a 12 volt battery. Thus, while an “empty” LiFePo4 may measure less than 1 volt with a voltmeter this is only because the BMS has intervened. Using the proper charger, the battery can quickly “wake up” and be recharged to full capacity. I purchased four batteries at the same time. After charging each of them separately, only two had resting voltages of at least 13.46 volts, which indicates 100% SOC. One had a voltage that equated a SOC of only 85%. The other one was somewhat higher but still short of 100%. While this can indicate a defect in the battery, in a new unit it may just mean that the BMS needs to be reset by discharging it to the point that the battery appears “empty” and has gone to “sleep” and then fully recharging it. The DC House instruction manual does not explicitly describe how to perform this BMS reset function. I used a computerized battery analyzer to discharge the battery that showed 85% SOC. I set the target voltage to 8 volts, knowing that the protective function of the BMS would enter “sleep” mode before this voltage was reached. During the discharge process, the battery provided over 100 Ah of power, indicating that the cells were good. After recharging the battery with the 20 amp charger, the resting voltage exceeded 13.46 volts, indicating 100% SOC and that the BMS had been reset by the discharge and recharge procedure. I followed the same procedure with the other marginal battery with the same result. Note that routinely discharging a LiFePo4 battery to the point that the BMS steps in to protect it isn’t a considered a best practice and can reduce the number of charge/discharge cycles the battery is capable. It can be done in an emergency or to force a BMS reset. However, if it happens routinely it probably indicates the need for higher battery capacity. If you plan to use these or any other LiFePo4 batteries in series and/ or parallel, be sure to research how to equalize voltages first. There are several ways to do this and devices that automatically ensure that this occurs. If you need a 24 or 48 volt battery or a higher capacity battery consider whether it would be better start with it rather than using several smaller batteries in series or parallel, especially if you aren’t familiar with battery banks and how to configure them. This is not a criticism of these batteries but just a suggestion to consider. All in all, I am initially quite happy with these batteries. Should this change, I will update this review.

I purchased four of these LiFePO4 batteries to replace the lead acid batteries in my Ryobi RM480E riding mower. The original batteries worked for 5 years, but one had failed and the others were old. These were higher capacity batteries (100Ah vs 75Ah). They proved to be a drop-in replacement for the existing batteries (they were just a bit taller, which caused no issues, and a bit narrower, which required moving the adjustable plate that holds them in). They wired in with the same cables, in the same order. Each battery weighed in around 22 pounds, much less than the 50 pounds per battery with the lead acid, which should also provide longer runtime. I had to replace the Ryobi original charger with a LiFePO4 capable charger, but that was the only change needed. The batteries have run the mower wonderfully. The charge holds for hours of heavy use in tall, wet grass or pulling a thatcher in multiple passes around my yard. No issues with longevity or delivering enough current to run the mower. No problems with using the mower for a long time on a hot day. A full charge, with the charger set to deliver up to 13A (seems to deliver a max of about 9.6A), takes about 4-5 hours from a full discharge. The mower is kept indoors in an integral garage (part of the house), so the batteries are not exposed to excessive heat or cold, which should help extend their life. I am very happy with the purchase. I expect to get many more years of life out of these than the lead acid batteries could provide, especially since the LiFePO4 batteries are not vulnerable to the sort of damage that a deep discharge could do to the lead acid batteries.

After switching to the DC HOUSE 12V 100Ah LiFePO4 batteries in our RV, replacing our old AGM batteries, we've noticed a significant improvement in our travel experience. Here's our detailed review: **Pros:** - **Lightweight & Compact**: These batteries are a game-changer for those who are conscious about the weight and space. We were able to install them easily due to their 30% weight compared to traditional lead-acid batteries. - **Longevity**: With a life cycle of over 3000 times and a lifespan of up to 10 years, these batteries promise to be a long-term investment. Hopeful it's the truth. - **Safety & Certification**: The advanced Grade A LiFePO4 Cells and UL/UN38.3 certification give us peace of mind regarding safety and reliability. - **Warranty & Support**: A 3-year warranty and the promise of comprehensive after-sales support add to the value of this product. But we didn't used it so far. **Cons & Concerns:** - **Voltage Concern**: Upon full charge between the recommended 14.2-14.6 V, we've observed that the voltage always decrease to 13.2V within an hour after plug off the shore power or solar. This seems slightly off from the expected 13.6V (or at least 13.4V), which is stated in the manufacturers manual for a **full** battery. While this doesn't seem to affect performance (the Voltage stays at 13.2 V for a very long time) , it's something we're keeping an eye on. **Overall Experience:** We've been using two of these batteries in our RV, and they've handled all our power needs efficiently. The automatic BMS should working flawlessly, providing protection against overcharging and short circuits. The wide application range means we can use them for various purposes, which is ideal for our versatile travel needs. **Verdict:** We're awarding 4 stars due to the voltage observation. However, we're monitoring it closely to see if it impacts the overall capacity. An update will be posted soon to share our findings. For now, we're pleased with the performance and would recommend these batteries to fellow RV enthusiasts looking for a reliable power source.
