Review: Price to Watts is fantastic - UPDATES at the bottom of this post: I just got 2 of the 12V 100Ah Black units a few days ago so future edits will be added. So far I was impressed with the shipping time and packaging. They were individually packed in very strong cardboard boxes with custom fitted foam protection. Shipping took about 3 days to get to my door. They arrived with about 40-50% charge. Very impressed with the weight compared to traditional batteries. If you have ever lifted or handled car batteries, you will be surprised as to how light these are. I went with these batteries due to their price point. Most LiFiPo4 batteries are well over $250 for a 1200W battery but these were $180ea when I bought them. I plan to use these on a small solar power backup system. I will pair these with 400W (peak) solar input through a MPPT controller and they will power a 2000W pure Sine Wave Inverter (always use Pure Sine Wave if you plan to power ANYTHING with a motor, fridge, A/C unit, freezer, fan ect...) I will update after I put these through several cycles. UPDATE July 12, 2024: I have since bought another one of these (100Ah, Black, No Bluetooth) making a total of 3 batteries. I haven't needed to use these all that much, but I have deep cycled them 3-4 times in the past 3 months and have had 0 issues. I have used them as a temporary power source plugged into an inverter during two different thunderstorm power outages, and I have used 2 in parallel to power some power tools in remote areas of my property because I didn't feel like hauling my generator up a step hill. These batteries are pretty easy to tote and was the lazier option. Once I'm 100% sure these batteries are safe, I will setup 3 in parallel attached to 500W of solar panels as a primary power source for my workshop. UPDATE 12/08/2024: I have been using these 3 batteries now for several months. I used them heavily to build a concrete building in a remote area of my property. These batteries powered my electric cement mixer, SkilSaw, Power drills, and lights over the course of several weeks to complete the construction of my Shop. I now use these batteries as my shop's primary power source. I charge these batteries from a 400W solar array controlled by an MPPT. So far, these batteries have had 0 issues. I probably won't do any more updates to this post unless something changes. At this point, I feel confident that these batteries will be a reliable power source for years to come. Final Edit: It is October 8, 2025. These batteries have since dropped in price so I bought a 4th. The 4th battery doesn't seem to keep the same voltage as my other 3 do. Every few months, I attach my batteries to a charger designed to charge / maintain larger LiFePO4 batteries, I charge them all up 1 by one from the same charger. My first 3 batteries charge to about 14.4 volts and will stay at around 14V for the few 100W of usage, or for 2-3 days after a full charge, typical for a 12V 100Ah battery. The 4th battery will drop down to 13.8V within 1-2 hours after a full charge. I charge it at 14.4 volts just like I do the other 3, but it seems to want to run slightly low. This doesn't seem to effect the performance as it still seems to run my inverters ok, just something to note. The other 3 batteries that I have been using every day for over a year now are still working great, I keep them well maintained and never let them get fully drained. I am a little wary now that they dropped the price to $110, hopefully they are just trying to clear out their stock...
Review: Good batteries so far - I bought 2 of these about a month ago, and so far so good. At the time of purchase they were below $300 each, and I said once I saw a LIPO4 battery at this price point I would buy. I replaced 8MM bolts with some terminal extenders since I had 5 different sets of wires attached to it. Replaced 2 75 AH Optimas on my Winebago View that we're getting shot due to over discharge and 3 years old. First off these batteries were a lot bigger than my old batteries. I thought I was going to have to cut into battery box to get them in, but then a friend reminded me that these can be mounted end up. They just fit on their sides! A few things I learned this weekend. The BMS works. This is not a fancy battery and has no Bluetooth to monitor. I overdid it one night trying to see what capacity I had and my Inverter alarmed about 4 in the morning. The batteries were at 10 volts. But at this point they were too low to start my generator! I started up engine and tried to charge by the alternator. But they would not charge since it was below 32 degrees! Actually I was happy about this once I realized how cold it was. Once it was warmer I charged them back and no damage done. No fancy frills but good price for these batteries. Still no word on what kind of warranty they have, there is no mention anywhere and I asked question and has still not been answered. Worth the risk for the price.

### ⭐⭐⭐⭐ Read This Before You Buy a Lithium Battery
*by A***R on March 31, 2023*

I bought this battery to replace a regular wet acid battery to run my trolling motor. It worked great for 2 weeks then went 'dead'. I tried to charge it and it would not accept a charge at all. I put in for a return and had printed out the return label already. Just before taking the battery to the post office i began to look up other 12v Lithium batteries to see if there was something better or maybe i should go back to a regular deep cycle wet battery. Then i discovered about the BMS system: IMPORTANT! The Lithium BMS system has a built in switch than can turn OFF a lithium battery. There is NOTHING wrong with your battery if that happens but if you dont know about the BMS turning your battery off you will think you have a dead battery. There are a number of ways to "wake up" or "turn on" your battery by telling the BMS system to do just that. I tried once before to post places that show you easily how to do that but Amazon wont let me post a link so here is how to find out how to do it. Do a search to watch videos on how to wake up a lithium battery. If you buy a lithium battery or have one now that goes dead try to wake it up first.
