First charge seemed slow but that might be the chargers fault. Very heavy at 61lbs each. So far, great batteries, I bought the 2 pack. Bluetooth connected and works fine!

I bought 8 of these to replace an aging off grid Flooded PB array. Cost was comparable to PB and the performance is far better with less maintenance. Using an old android phone (EasyDesk) and WiFi, I am able to remotely monitor the battery individual status via the included internal Bluetooth BMS.

This review will just be a delivery and setup 1st time, charging, and Bluetooth dependability and customer support. I will add to this review after installing them on my pontoon to run my Garmin graphs and force pro trolling motor. (36volts) I am in a wheelchair and wanted a battery system I can count on ,not running out of juice while I'm out on the water. My trolling motor can work on 24 volts or 36 volts. Originally I bought this 2 pack on sale and paid 741 dollars delivered. I paid 750 dollars for a 100ah battery at Bass Pro and seen these with 280ah each, and thought, man for the same price I can have 560 ah and run my motor for probably the whole weekend. I actually wanted to run my motor off 36 volts, so I had to add a 3rd battery. What I didn't know was they don't recommend combining batteries that aren't the same make, brand and amp hours!! I was going to just add an extra 100 ah battery I use in my motorized kayak. They say that could cause multiple problems and even damage the new batteries I just bought. So I bought a 3rd eco-worthy 280ah so everything would be identical. I really didn't need 840 amphours to run my motor but I couldn't return them, so I just went with it. It makes sense though, when combining the batteries, they all have bms protection so you want them all to have the same specifications. Even though I bought all 3 batteries then I find out they need to be charged by a 36 volt charger , unless I want to unhook them and charge them separately with 12 volt lipo chargers. So I grabbed a quality 36 volt charger on Amazon made by LiTime because I had a 80 dollar credit from them I needed to use. So then I think, im good now and everything should be fine ..... Nope!!! Now they say if you want them to last a long time, they need to charge and discharge within .1 to .3 volts of each other. So then I buy what they call a battery balancer. Only around 75 dollars, but to protect my 1000 dollar investment, how could I not get one? I know this is a long review, but im hoping it helps other people that might be wondering what all they need to upgrade their boat from lead acid batteries to lithium. So now it's winter in Michigan and won't be installing them until spring. So back to the original review, I got them delivered in a couple days, packaged very good. They came with around 25% charge on them. The paperwork has a QR code that basically registers them and activates the Bluetooth in the app so you can see the state of the batteries. I charged both to 100% and the app shows you a lot of information. Even shows how many amps your charger is applying. ( nice because most of these chargers just have red or green blinking lights and you have no idea how long the charge is gonna take..) Also my chargers claim they are 20 amp chargers, and I was verifying that by it showing the amperage between 19.2 and 19.8 . The app also shows the 4 individual cells each battery is made of, and shows you if they are balanced, ( like i talked about earlier) so the BMC in each battery, balances the 4 internal cells, but when they are connected in series to get 36 volts, that's what the extra balancer i bought does.) It balances the 12 cells in all 3 batteries, not just charging, but also balances them while discharging. I had a few questions and customer support got back to me quickly, and answered all my questions. I was surprised with the Bluetooth, I had them stored in a metal shipping container to be out of the weather and I was getting signal in my car over 40 feet away, and I checked the voltage and few times a week and they stayed the same. Maybe lost .001 or .002 volts a week. It's been about 3 months and all 3 batteries are still 100% charged and never have a problem hooking to the app. So for now im happy with them and once their up and running in the spring, I'll update my review and i can't wait to see how many miles or hours my trolling motor will go on 840 amp hours.

We use these in our camper van and they really hold up and give us all the powere we need. Even when we don't go out for awhile they stay energized. We think they are a really great investment.

This pair of 280AH LiFePo4 battery works great, if my meter is any good, it registered 290AH. Like other 12v LiFePo4 batteries, they all list 14.6V as charging voltage. They may work well in standalone charger with 14.4v for boost, float and equalization voltage, those voltages are not for off grid system that are active 24/7. The BMS in this battery and one of my other brand battery will disconnect the battery from the system momentarily when the charge controller voltage reaches 14.2v, then reconnects to see if the voltage is below 14.2v and stays on if it is, repeating this process continuously until something breaks or break the cycle. This is fine in a standalone charge system, but in the off grid system charge controller will output overvoltage when the battery disconnects, causing the power inverter to shut power to your appliances and power back on when the battery reconnects, like flipping the power switch on/off to all your appliances every few seconds continuous until the solar power output is below the appliances power load. Power spiking to your appliances is harming and eventually burn them out. Fortunately my Renogy 100A charge controller has a user define setting for battery type, which allows me to set the voltages to 14.1v just below the threshold for the BMS to disconnect the battery, avoiding power spiking in my 24/7 off grid system. The 14.1v settings is just my trial and error setting to get the around the BMS overvoltage protection issue, I wish ECO-Worthy tells us what the user define boost/float/equalization voltage setting should be for off grid system running 24/7 and still get the most storage capacity from the battery. My old green label battery brand starts with letter J works with standard 12v LiFePo4 battery setting without power spiking in my fully charged (14.4v) off grid system running 24/7 for a year without any issues, but they have been awfully quiet for me to make any further upgrade investment

I have bought 12 of these batteries so far. All are working just fine. Had some technical issues with the newest batteries that included blue tooth monitoring. It took about a week of correspondence with the company to resolve some minor issue with recharging and having the blue tooth saying the batteries were fully charged Some technical person named Dante helped me through resolving the miss steps. The quality of his service and keep checking back to see things were getting resolved deserves a A++ grade I will continue to buy and promote their products because of his efforts high five for helping me you are the best!
