ECO-WORTHY 12V 300AH Lifepo4 Lithium Battery Bluetooth with SOC LEDs and Low Temp Protection
I’m am a little disappointed that I can’t control the battery more mainly turning it off at the battery posts like the 280 battery I purchased from your store.With the solar overkill app.please look into that.Safety First.
Thank You
Regards Randy
Just got it installed to replace 2 Lead Acid batteries. Works great in the camper I use a DC to DC controller from the Alternator and also from shore power going through the onboard converter, charging just fine.
I love the battery. It looks good, is well-designed (I really like the “swelling containment” aspect of its case that will keep it working and not distort the outside of the case even if the battery were to swell up a little), and it works great. But the first time I charged it when I got it (which takes a while on a 300 Ah battery), I excitedly watched on the cool Bluetooth app as it slowly took a full charge. But when it got to 97%, the Bluetooth shut down and the app couldn’t see the battery anymore. The red LEDs on top of the battery showed the level of charge so I wasn’t completely in the dark, but I really liked the functionality of the Bluetooth app. I'm working with their support team, so hopefully we'll get this resolved. I looked online and saw that others had experienced what I did, and a workaround suggested was to run the battery all the way down, then charge it again. That worked! I was happy. So I started charging it again. And again, the Bluetooth shut down as it got near a full charge. I have another battery meter on my auxiliary power system, so I can get a rough idea of the state of charge, but I would have preferred the more accurate reading the app gave me (when it was working). On the plus side, I bought this battery after buying a competitor’s battery, which failed before I could even use it, so you’ve got at least that advantage over your competition. I figured I’d return the competitor’s battery and use the Eco-Worthy, but then I discovered (my fault, I didn’t read the fine print on Amazon when I bought it) the competitor’s battery was not returnable. But at least their support team responded to my inquiries and replaced the battery. So now I've got two 300 Ah batteries, which will give me all the off-grid power I’ll ever need. So there’s that. I do like the battery a lot. The app, not so much.
These batteries appear to be great. Nice looking great size and well packaged. After charging, one charged to 302ah the other 296ah. Manuel could be improved by including recommendations for victron solar charger profile.
