Purchased 2 of these batteries to run in series for my trolling motor. These batteries so far have proven to be absolutely amazing. I took my boat out for the first time yesterday, and was on the water for 12 hours, most of which I used the trolling motor and my light bar that is also hooked up to the 2 batteries. At the end of the trip, I had 69% battery remaining, and unlike my lead acid batteries I had prior, I saw no decrease in performance. As a matter of fact, I feel like the trolling motor ran better (less vibrations), although that may be in my head lol. It really made my fishing trip stress free not having to even think about what my batteries are doing or when they will die or slow the motor down. Tons of pros for these batteries: 165AH and a metal case and still lighter than my 96AH lead acids. The app is actually really good, and I can connect to them inside my house while they're charging outside in the boat. (the app is very detailed, showing watts in and out, percentage life left, voltage and more) No power decline unlike lead acid No fear of discharging more than 50% Price is amazing, roughly $80 more than a cheap lead acid battery. There are some things I dislike: The case is a very odd size. It is much taller than a normal battery, which doesn't bother me too much. However, it is also wider than a standard battery, meaning that it doesn't fit in any battery trays. I put some adhesive rubber feet on them to keep them off the deck, and used some stainless cleats and a battery strap to secure them. Not sure I'm a fan of the case being metal strictly due to increased weight, and long term exposure to the elements being that they will be on my boat. I tried to email DC HOUSE and ask what type of metal it was constructed of, and was told "metal". The side mounted terminals aren't my favorite either due to the increased risk of accident touching, however these batteries do come with terminal covers that are nice and pretty roomy for your leads to fit in. Overall, these batteries have very much exceeded my expectations. I was hesitant in switching from my old deep cycles to lithium, but these have so far proven to be an amazing replacement. The cons I listed are really unique to my usage, so I can't knock any stars off for that. If you are like me and wondering if it's worth the switch from flooded batteries to these, don't hesitate.

I purchased this battery for $219 in December 2024, and for the price, I believe it offers excellent value. The 165Ah 12.8v capacity is impressive, especially when compared to other options in this price range. What I Like: Great Price: For $219, the battery offers a high capacity at a very competitive price. Large Capacity: 165Ah is more than enough for most uses and gives you peace of mind for longer power usage. Sturdy Construction: The metal casing and handle are a nice touch. The build quality seems solid, and everything looks well-assembled (I haven’t removed the BMS or inspected the cells themselves, but the top view suggests a high-quality build). Great Performance: The battery held up well during my testing, and I was impressed with its capacity and efficiency. What Was Odd: Voltage at Full Charge: At full charge, the voltage reads 13.4V, which is lower than what I’m used to. I have several LiFePO4 batteries from EG4, and they all charge up to 14.4V. However, after troubleshooting, I realized this was due to a compatibility issue with my charger. Once I connected the battery to a Victron MPPT, it was able to charge up to 14.4V, and I gained an extra 1Ah of charge. So, this is not a problem with the battery itself. The BMS was correct to show 100% state of charge. Testing the Battery: For this test, I used a budget battery monitor, which isn’t highly accurate but serves well enough for basic testing. The monitor readings were consistently around 3% higher than the readings from the BMS, so the capacity I registered might be slightly inflated compared to what I actually extracted. The battery was discharged using a Harbor Freight Jupiter 1000W pure sine wave inverter, running an electric heater. The test lasted until the inverter shut down around 11V. This isn’t a typical 20A discharge test you might see online; instead, it’s a more realistic test for normal usage, as I didn’t drain the battery to its last drop. BMS Estimation: At the start of the test, the BMS estimated around 2 hours and 15 minutes of runtime. The actual result was 2 hours and 11 minutes (see photo). Capacity Used: I was able to extract about 2.03 kWh or 161 Ah before the inverter cut out. The battery itself didn’t shut down during the test. The BMS temperature stayed between 82-90°F throughout the test, which is a good sign that the battery was not overheating. Conclusion: Overall, I am very pleased with this battery. It has performed well beyond my expectations, offering reliable power and a substantial capacity at a very reasonable price. Compared to an AGM battery, this LiFePO4 option has much more usable capacity, and I’m confident it will last much longer. I would definitely recommend it to anyone looking for an affordable, high-quality battery. Read more
My decision to purchase the DC House 165 amp hour, 12V battery was based on the specific needs of a project I planned. While looking at an unused mechanics rolling tool stool I had on hand, I decided it would make a great platform for a DIY power station. Already having a 1000W inverter and a 30 amp solar charge controller available, all I need was a suitable battery. The battery had to meet several criteria. First being physical size, it had to fit in the space available. Second, I wanted at least 2000Wh of capacity. And most importantly, it had to have Bluetooth capabilities, to simplify monitoring, without having to buy an additional monitor and install a shunt. The DC House battery not only met these criteria, but had the additional advantages of a metal case and an extremely reasonable price. My research also indicated the battery was well built and highly respected. Upon receiving the battery, it was fully charged with a dedicated 20A, LiFePO4 battery charger. It was then discharged, running my TV system, at about a 220Wh rate until the inverter shut down on low-voltage. The battery easily made its 2112Wh rating and recharge on solar without issue. The Bluetooth connection was easy to set up and it stays connected well. Monitoring the battery status during both discharge and charging cycles was simple and easy. Overall, I’m very happy with the way the project turned out and extremely happy with the DC House battery. This battery brand may be one of the best values on the market today. Read more
