He comprado tres de estas baterías para el sistema solar que estoy haciendo en casa, el rendimiento es muy bueno con estas baterías, la calidad de construcción se nota y las pruebas que le han realizado han sido muy exactas, justo con los datos que tiene en la descripción

Use:Battery swap and UPGRADE for 36v gold cartQuantity:3Weight:-22lbs each! (For a total of 66lbs)-I switched from 6 Interstate lead acid (55lbs each totaling 330lbs) losing 264lbs from the cart and it certainly feels it!Charger:-Updated to an on board charger (15amp Noco Genius "Gen5x3")-I keep it connected to my batteries and simply plug it in when I'm done using the cart. It charges each battery individually and stops charging individually as well.-I'd go bigger maybe 20amp or 30amp if you want a fast charge. It works well, but it did take aprox 14-16 hours to charge them back to full after the trip mentioned below.Practical test:-On 07/12 the wife and I took the cart out on a date night The new batteries on a full charge read right at 42v on the voltage meter.-That night we drove 24.2 miles over the course of 4 hours averaging 14mph with LED headlights ON-When we got home and they read at 39.1vPARTS USED FOR BUILD:3 of these batteries- $187.99 each1 Noco Genius "Gen5x3" $187.991 Pair of 8in wires (golf cart wires)-$121 Pair of 14in wires (golf cart wires)- $142 Longer terminal bolts(aprox 1.25in)- had'em1 Master kill switch- $13-This helps make sure not of my accessories aren't leaching my batteries-IMPORTANT: Using this became the connection point from the far end of the sequenced battery + side to the positive cable coming directly from the cart (I would have had to buy a very long cable, one and then connected them with a creative solution) GET the SWITCH.GRAND TOTAL for swap:$790.96NOTES:-The bolts (Phillips head) that the batteries come with are pretty short but worked for all the terminals that were minimally occupied (battery charger &battery charger and cable).-I had to use some longer ones on the terminals that I tied my accessories intoOPINION:I was extremely skeptical making the switch and opening the money. I could find but 1 other review that did this swap, it was very helpfulDo the swap! If your hesitant it's understandable but these are less expensive (overall), light in weight (your cart will go faster) have better longevity and can run for longer periods. I believe the batters would have kept running after the trip mentions above.I am so glad I did! For the money the outperform lead acid, save a ton of weight on the cart and should last 3-5x times as along!

Light weight and heat price

I needed to replace the battery in my boat I use to run my 12 inch UHD2 Garmin unit and Livescope. I have a friend who had bought this battery in a lower amp hour version and has gotten great use from it so far. I read its specifications and it seemed to be a well made battery. The price was equal to a lead acid battery instead of being the jacked up price of a pure lithium.I knew I would have to buy a battery charger either way so I ordered it. I have been using it for 3 weeks, running the 12" Uhd2, Livescope "black box" and a 9" unit. I start off my mornings showing from 13.4 -13.6 volts and after 8 hours of fishing still show from 12.9-13.1 volts and according to the charge lights on the battery case it is still at 3/4 charge.My livescope is showing up much better / brighter. So far I am thoroughly pleased with this investment. The paperwork with the battery said it could be charged over 4,000 times and should last 10 years. If it does, and I'm still able to get around then - I'll be buying another just like it.

So far so good. This battery has been doing all that I ask of it. I’m currently running a 600 W inverter and plan to expand my system as necessary. Will update this review if anything changes.UPDATE: 4/4/25 I now have 6 of these batteries! They all are working great! My end goal is a 16 battery bank giving me 48v at 400AH. My calculations show that this will run an air conditioner or electric blanket over night with no issues! I’m glad I chose these batteries as the price is right and the quality is great. I will say you save about 10 bucks buying from their website directly. The lowest price I’ve paid was 139.99 at the time of this update 141.99. Who knows where they will go under the new tariffs?

Been exploring solar options and tried multiple brands of batteries. This brand uses high quality prismatic cells. Four 3.3v rectangular shaped. Internal BMS not employed because I'm careful not to go outside battery parameters. Have not needed warranty support on this brand but buyer beware I have had vendors claiming to support without returning emails

2/3 batteries arrived and would not accept a charge from a charger with the exact specs they recommended. Now they've charged me 1/3 of the product cost to return, but didn't tell me about that 'fee' before sending back their junky products. Complete rip off, stay away from this brand.

This is my second DJLBERMPW 12V 100Ah LiFePO4 and they work great. I have connected them in parallel and used my 150W constant current electronic load tester on the pair and the test results were 206AH and still going with just a little over 10v left on the battery bank, I have done this now a few times now with consistent results I say that's a win. I can not comment on the longevity only having them for a month or so. The MFG dates are within a few months of receiving them so they're fresh builds and the quality is outstanding. I am very pleased with the batteries and plan to order a few more, the first 2 are for a 24ft camper I would like 2 more for my boat and possibly a 5th for the camper. I recommend trying them I think think they are a great value and quality and should last.
