ECO-WORTHY

So far so good! Installed in my boat for 6 months. So far great. Seems to stay balanced well. Bluetooth is fine, but app needs to be rebooted after a bit. Once I understood that bug, I can live with the lost connection. I use two Victron smart solar controllers and 2 Orion 50 amp b2b. To charge. Boat lives off grid.

I have 8 of these (2 series of 4 wired into parallel). I am happy with these batteries’ performance and value, though I wish I had gotten the version where the BMS communicated with the inverter. Since I didn’t I’ve had to set the inverter to treat these batteries as Lead-Acid and estimate the State of Charge by the voltage (which is very imprecise). They get the job done though.

I've been using two of these in my truck camper and they work great. Replaced my lead acid deep cycles and I was so glad to see them go. I run 4 camper jacks at once after they have been sitting for weeks. Love them.

After install, I discovered that the BMS was not working, the battery charged and discharged just fine. When I contacted eco-worthy, they said to try and update the software, but that required a Windows computer that I do not have, so they sent a replacement battery and a prepaid return shipping label. I know it sounds simple, but if a product does what it supposed to and a company fixes it when it doesn’t I’m very happy.

I bought this from AliExpress when it was on sale and I got $42 off extra. $265 before taxes in June 2026. The battery came in a really padded box and got to my house in 2 days from a local warehouse. The metal case is strong and the cells are bolted into a metal frame and then the frame is bolted into the metal case. There is a power button and two terminals with recessed screws around them. The physical build is very good. The BMS is a JBD unit and it hooks up to Overkill solar app, which is nice. The manual tells you to use the Elephant app but Overkill works, too. The cells are not perfectly balanced at full charge and the balancer is too weak to balance them. I would probably need to spend several weeks or more with it in absorption mode to balance the three high cells down. You can remove the cover and charge up one cell but I don't have a bench top power supply yet. The AliExpress listings all show the big orange sticker on the side by the new models are all screen printed white and blue on the sides.

It was easy to setup and I have not had any problems so far. I have used it with 1 Vatre server rack battery and have just purchased 2 more of the same batteries and have yet to install.

I bought 2 of these batteries bundled with a 5kw inverter off of Amazon to build a hand truck dolly solar generator for home backup. These cubix 100 batteries have been working very well. Afters months of ownership ecoworthy has worked hard to keep my business. They have made great updates to the app to make it run smoothly, their Facebook page has been helpful. The two batteries have 15 cycles through them and have worked without any issues. Arrived very well packaged with no damage. Setup was super easy and ecoworthy have youtube videos to help if you get stuck. The battery life is getting better every cycle. Since i purchase the two initial cubix 100 batteries I ordered two more arriving tomorrow. I trust these batteries to keep my 6 essential circuits running when the power goes out and I'm excited to add two more. Buy with confidence.
