LiFePO4 12V 260Ah Lithium Iron Phosphate Battery

With only a week worth of usage, they are 10x better than any deep cell marine battery i have used. Would recommend.

Package and product was in perfect shape. I put the battery in a 2019 Coachmen 187RB under the rear dinette seat. There was a perfect place there and it help lighten the tongue of the lead battery and put some needed weight behind axle and on the curb side. I replaced WFCO 8735p onboard converter with a WFCO 8740 AD. It appears that the battery indeed had a half of charge and the 8740 leveled off its initial charge 5 hours later at 13.62 to 13.64 volts. A little earlier to tell how many amp hours I will get. I also installed an eco-worthy 1100 watt inverter. Without charging the battery I turned on the inverter and plugged in a portable Hoover vacuum cleaner drawing 850 watts. It did not phase the inverter nor the battery. I then plugged in the vacuum to a electric company supplied outlet and there was no perceivable difference in the performance of the vacuum. Next year we will see how it performs on the road to Alaska.

Great product. I like it

I got the battery on time and intact. It was nearly fully charged, so I left it alone. It is lighter than a comparable lead acid battery which is a good thing. My intent is to use it to power an inverter to power a small AC unit in my boat. The battery will be charged by the main engine alternator when cruising.

No show stoppers encountered yet and hopefully none will be.

Our boat House batteries were 6x6v Lifeline AGM arranged in 3 parallel banks of 2 in series and which were in poor condition. These were 200ah giving a total bank of 600ah.
The replacement cost of these batteries was over $3000. After a lot of research I decided to change to Lithium and chose to replace them with 3x12v 260ah Eco Worthy LiFePO batteries in parallel.
Not being familiar with Lithium I initially didn't realize that they come less than half charged (this is normal). We have an excellent Outback VFX2812M 2.8 kw Inverter charger and everything was rewired with 2/0 AWG cable and Wirefy 2/0 AWG solid copper lugs. When we connected everything up the inverter was charging the bank at over 100 amps. When the full charge value of 14.6v was reached they just stopped charging. (With lead acid you would have an absorb period and this doesn't happen with Lithium).
I then turned on the microwave oven and the electric kettle and switched off shore power.
The lights didn't even flicker The appliances just continued to run from the inverter powered by the new Lithiums.
(There are similar capacity LiFePOs out there for sale with the ability to monitor the cells over Bluetooth but these were almost 3 times the price).
I found that running high current loads doesn't produce any noticeable warming of the batteries and they seem very well made and excellent value for money. I was able to save over $1000 and get more capacity (780ah against 600ah) in much smaller space. In fact the container holding the end two AGM 6 v batteries has now become a handy storage bin!
One positive aspect I didn't realize would happen is that because Lithiums have much smaller internal resistance the charge current from our solar panels is much higher and doesn't tail off as they charge, so the batteries recharge much faster from the panels.
So, I am really pleased with my Eco Worthy batteries. I can highly recommend them.
(We currently have two Kyocera 140 watt panels in parallel and I noticed that Eco Worthy are producing a higher output panel with approximately the same footprint so we are looking closely at them).
