DR.PREPARE 12V 100Ah LiFePO4 Battery with Updated LED Meter, 1280Wh Group 31 Deep Cycle Lithium Iron Phosphate Battery with 100A BMS for RV, Trolling Motor, Solar Power, Off-Grid, Home Energy Storage

First full charge then discharge to 10.5v with a fast bounce back to 11v. I'm happy so far. This was a 2 amp rate and it held extremely steady till the end. A heavier test will be next. Before I run the second 20 amp hour battery test though I have fantastic results from the hundred amp hour battery that I also purchased! I had to baby my tester as much as I could to pull enough juice out of it in a reasonable amount of time but I managed to get 99.12 amp hours and roughly 9 hours 57 minutes at about an 8-10 amp draw rate. I'll admit these are the very first charge and discharge tests on these batteries that I've received within days of this post but I will continue to test and I will update on each of these batteries if anything changes for the worse. So far though $120 for $100 amp hours and $46 for 20 amp hours is a pretty good deal!

This big battery that cost around a dollar per amp, not per watt. I have use it for running my small microwave over as 100% off grid. This battery has came in almost dead, that has taken so long while to charge it with 20 amp charger. If you use it on average electric car, that will give you around 10 to 12 miles range. At first I had saw Dr Prepair, at first; I thought it Dr. Pepper HA-HA. After I had saw from Will's on YouTube, as he is is impressed of the built quality. This single battery is so great for trolling motor for you boat with 3 times longer run time that much heavier lead acid battery. You will getting around 1 extra MPH of speed.

Very good life batteries, very nice to have an charge inducator

Seems to work ok. But no Bluetooth to see info on an app. I thought I ordered the Bluetooth one but here I am. Hooked it up to a shunt to hook screen monitor to. Not that big of deal. It is nice to have that storage of power for night time camping.

Surprised me , replace 8 6 volt batterys that weighed over 480 lbs with 4 of these . Works great . They are 27 lbs apiece which is 108 lbs .

First of all, as far as the products go, it seems they most of the time do well, I just got a faulty battery from the beginning. My problem is with the customer service and seller. One of my batteries wasn't charging equally with the other no matter what we did. Charged it separately and no matter what it would never charge equally with the other battery. Anyways, got in contact with the seller after a few months and they basically told me that it's fine... Well it wasn't, lifepo4 batteries are not supposed to do that. Fast forward a couple years and the battery that was having the issue just dies on my randomly, so we disconnect it from the other and are able to eventually bring it back to life. A couple months later it quits again out of the blue shutting down my whole system, so I reach out to customer service for a replacement battery since it was under three years old as the warranty states that a replacement battery will be provided. After they sent me through a ton of hoops that took days of communication before they would offer any kind of replacement, we were able to get the battery to charge right again, but at this point the battery cannot be trusted anymore after failing twice that close together. To which the company said the best they can do is a 50% discount on my next order, like I would ever buy from them again. At this point I looked up their warranty and told them that their warranty stated that if it's a manufacturer defect they must either replace the battery with a new or refurbished battery or refund a certain amount depending on how long I've had the battery for (which they have the order date on file by the way, they should know this). They then told me that yes this is true, and that they could offer me a 50% refund or a refurbished battery, but the battery may be a few months because they didn't currently have any refurbished ones to send out. After looking at my order date myself I realized that my batteries weren't over three years old yet, which under the warranty policy means they have to with provide me with a brand new battery, or an 80% refund. After telling them this they said that yes that is what the warranty states and that they would now assist me with a new battery (all of this u had to fight tooth and claw for), but that they needed me to send back the bad battery to them through a fed ex pick up, which where I live does not work, fed ex can not get to me. Also no fed ex stores around me can accept batteries due to hazardous material laws. When I told them my problem they proceeded to ignore me for days....and days... Until I finally got sick of it and told them I would just accept the 50% refund since I couldn't do the FedEx pick up. Guess what? they got back with me immediately after that and told me they would do the 50% refund.... Shocker. Either way, the other battery I got from them originally seems to be an okay battery, and they're products seem to be decent, but do NOT expect them to stand behind their warranty or help you out if you do have problems unless you fight them with every step, and are also willing to quote their warranty to them. They want to do the BARE MINIMUM.

The shipping was fast. On arrival, multiple tests were completed, and the battery performed better than advertised. The battery will be put into service on my 5th wheel RV, working in conjunction with my Pecron E3600 solar generator. This battery replaces my conventional lead-acid battery to power the many 12V appliances and lighting. The test will be over the next couple of months as we travel through varying winter conditions. Charing is a combination of 400 watts of solar and the RV's converter.

Works great haven't had any problems out of this battery. Have been going o 6 months now problems
