  • Best Value for a Well Built Battery!
This is not only a very competitively priced lithium battery, it is well built and has a lot of useful features to monitor your battery and it's performance. The bluetooth range is insane! People have always said "buy American" such as a company that has the initials BB, well we now know that those are high price and low quality. I highly recommend this battery. ... show more

  • Great product
So far this 300AH battery has performed well. It’s been in continuous use since installing into a 2024 bumper pull RV. These new RVs have a 12 volt only refrigerator now. Turning the refrigerator off is not an option when living in the RV. A good battery is needed to make it thru the night, and this one can handle two or more days without charging it. I like the Bluetooth monitor app too, super easy to use. I am on the road all winter in this RV, with many days boondocking. It’s kept charged with a 400 watt solar system. ... show more

  • first one did not live up to specification, Good warenty support.
Battery does not charge correctly. BMS cuts it off at 13.9V and never displays "full". Their ap works well over bluetooth and indicates cell balance is a problem. No idea if it will deliver that 300ah. However the state of charge SOC is wildly inaccurate and Remaining AH also off. Both often show SCO 100% and only 200Ah remaining. the BMS went weird, it was being discharged and now shows 100% state of charge and its clearly not! before that it was down to 90% and I was not charging it. Zero stars! its a dud. Its an expensive failure. I will not buy again and likely return. however they now want me to ship it and I didn't keep the box for a 61 pound battery I can barely lift I have received a replacement. So two more stars for customer interface and timely handling. I will alter the rating again if it works correctly. EW and I worked to diagnose the problem and their offer of a replacmment and return shipping was accepted. The replacement arrived and after charging and testing works properly. Overall Eco-Worthy handled the problem well and the replacement working correctly. For their service rating is not 5 stars. If I should need another I would buy again. ... show more

  • Solid lithium phosphate battery for my camper trailer
Very satisfied with this lithium phosphate battery. I installed it into my camper trailer with the battery box shown in the link below. It’s a solid box but weighs only 9lbs. It’s a bit pricey but well worth it. Keep in mind the box’s stated dimensions are external dimensions. The internal dimensions are smaller. However, the battery (16.3 x 8.46 x 10.24 inch) fits inside the box with some room to spare. If you don’t secure the battery it will slide and bounce around. To secure it, I cut some slots in the bottom of the box and used straps to prevent back and forth as well as up and down movements. Additionally I used rv leveling blocks to prevent the side to side movements. I drilled some drain holes in the bottom in case water gets in. The lid comes with a vent plug. Since this is not a lead acid battery that requires venting I sealed the holes up with caulking. That prevents rain water from getting in. There are still access ports around the edges of the box for wiring. So it’s not completely sealed by any means. However with the lid installed, rain water won’t be able to get in unless it’s super windy; hence the drain holes. The Bluetooth connected battery management system is awesome. I can now monitor the wattage each device consumes as they’re turned on. My camper comes with built-in lithium compatible power center as well as lithium compatible solar charger. So it was a straight forward install. I did purchase a separate ECO-Worthy 20A lithium battery charger which I used to charge the battery up before the install. It didn’t take long to charge the battery from 25% to 100%. When it finished charging, the built-in BMS reported the capacity at 303AH. Prior to purchasing the ECO-Worthy 20A charger I purchased the NOCO 5A smart charger which is supposedly compatible with lithium battery. However it was never able to charge the battery up. I’m assuming that it’s just too small for the the 300Ah battery. Lastly, it would be nice if the BMS is WiFi capable and it’s able to send you status notifications.

  • Solid build but doesn't charge past 292.5 ah.
The plastic case and build seems very solid. The integrated molded handles makes it easier to wrestle this little beast around. The state of charge indicator lights are somewhat helpful but the Bluetooth app gives more specific details about the state of charge. Despite having purchased an Eco-worthy smart charger compatible with this battery this battery isn't charging past 98%. It won't go past 292.5 ah. Pretty good but I don’t think they ought to advertise 300 ah if that's not what they are delivering. I deducted one star because of that. Update: After using the battery for one full summer on numerous outings in my tiny teardrop RV it worked great. My biggest power drain is my 12 volt frig. This thing powered it for five full days in 90 degree weather. Also supported my husband's cpap on all those days but one, we switched to a portable power station because this batter was getting low. Also, I have gotten this battery up to a full 100% charge. I am not sure if it just needed a chance to get some use or if it was me not being sufficiently patient. It is highly possible the problem was me, not the battery. I think it goes into a slow trickle charge the last part of its charging cycle which takes a lot longer to complete that when the battery is at a lower level. I added back the star I deducted last year because it seems to be fully charging as advertised. ... show more
