48V 100AH Lifepo4 Battery 5120W Built-in BMS, Up to 15000 Cycles,48 Volt Lithium Battery for Golf cart,RV, Marine, Boat, Solar Energy Storage, Camping, Trolling Motor

I liked it so much, I purchased a second one. Plenty of power, we use it with a Bodega refrigerator freezer combo when we go grocery shopping. It runs the refrigerator 45 min to the store, 3 hours of shopping and a 45 minute ride bck home. I have used it on 5 of those journeys and it hand plenty of power left. I put it on the charger after the 5th trip and it only took 30 minutes to bring it back to a full charge. I have 2 refers and 2 batteries. Very pleased with this brand and they are priced right.

I’m a DIY solar guy, with multiple small installations that function independently and often remotely. I have solar panels on my truck for charging my tools, on my greenhouse for running fans and lights, in my garden powering an electric fence, on my chicken coop automatic door, and even on an outdoor bathroom. Sometime soon I hope to build a large array to add even more functionality and further reduce our reliance on the grid. Batteries obviously play a key role in all these installation. Due to the high cost, I’ve mostly bought and deployed smaller capacity batteries with lower amp hours that barely suffice and sometimes fall short. For some time now, I’ve been on the hunt for a light-weight, affordable and dependable 50Ah battery that can serve as single-unit power stations for these dedicated off-grids installs, be easily transportable for on-the-go applications, OR be ganged together for larger stationary arrays.By every indication, the DJLBERMPW 12V 50Ah LiFePO4 Lithium Battery looks to be an excellent candidate. The battery came extremely well-packed, and just has a quality feel and look to it. They even included an extra pair of standoffs/connectors. You can really feel the difference in weight vs. lead-acid. Initial tests so far meet all advertised specs, and I look forward to getting a lot of use out of these.

Good value

Works very well.

I bought 3 of these about 8 months ago. When spring came around, I got them setup to run my trolling motor. Within a very short time, one of the 3 batteries started having issues with the BMS. For a while, I was able to wake the BMS and get it charged and in use. But it kept going back to sleep until finally it wouldn't wake any more. To exchange, I have to send it back out first. With it being peak boating season, I bought a 4th so I could avoid downtime. That 4th one also only lasted a couple of weeks. So now I have 2 batteries and 2 bricks.Voltage can read anywhere from .8v - 12v when its not charging. When I throw it on a charger, the charger will wake the BMS up, it will read 14+ volts, the charger turns off, the BMS triggers again causing the voltage to fall under again. I've tried 4 different LiFePo4 chargers, I've connected the good batteries in parallel to these, nothing solves it. My guess is either quality control issues or cheap BMS.

The battery comes well packaged, has handles to carry. Bought two initially, added one more along with two extra solar panels. I am running my pool pump motor with a total of 3 batteries and 1,200 watts of solar power. So for so good, don’t know about longevity and number of cycles? Overall, a good battery for the cost.

Haven't had it out in full time use yet but it seems to be a great battery so far. Package came on time and packaged very good so it would not be damaged. Very light weight and also came with a very nice manual on company's products and all specs on this battery and more. Showed me they have pride in their products and seem very quality oriented. Plus I got it on sale so that was a bonus. Using to power my trolling motor for my kayak.

So far so good. Tried on boat for one summer. Hope it survives the winter.
