ECO-WORTHY 12V 30Ah LiFePO4 Lithium Battery, 4000+ Deep Cycle Rechargeable Battery with BMS for Ham Radio, Fish Finder, Kids Scooters, Power Wheels, Trolling Motor, Replacement of 12V 35AH SLA

Got three to run in parallel for my shed and they are every bit of 150ah. BMS has been solid and the Bluetooth feature is pretty cool. Only thing was they didn't come charged and arrived at 30%, so you may need to charge them but it's not a big deal. Highly recommend especially for the price!

Initial impression is terrific. Arrived very well packaged. Had a 40% charge and after a couple days installed in my camper my solar panels had it charged to nearly 100 in less than perfect weather. Being able to monitor the remaining charge and current draw is really great. Only minor complaint is that the screw on battery posts are on the short side. I have 3 cables to connect, but managed to do it. Time will tell and I will update if needed.

Mounted sideways with no problem. Forward facing sonar readings very clear without interference. Small size made it easy to install in a tight space. Would recommend charging it between long fishing days. I tried to squeeze in 3 long days of 10 hours fishing/day (with sporadic but often use) and on the 3rd day the battery depleted early. This is probably normal as battery size/ratings are important. I use it for forward facing sonar (exclusively) and have heard the black box which converts the data may slowly drain a battery if left plugged (without disconnecting or placing an inline on/off switch). I do disconnect the batter after every use to avoid an issue. Seems to take a few hours for full charge. I purchased a charger that does not have a battery percentage gauge and wish I had, to more easily assess battery status. Easy to use and would recommend, just make sure it is rated for enough run time for your application.

I’ve got three of these in parallel. Not a lot of hours or load on them, both even a full cycle of charging yet. Fit and finish seems fine. The Bluetooth connection to my iPhone is a bit unstable, and doesn’t have a dashboard view at all - I have to tap into each battery to see anything beyond whether Bluetooth has dropped yet and the name and MAC. No draw or voltage or capacity without tapping into each individual battery, and only one at a time.These are app issues but affect the battery’s review since that’s a selling point.I intend to update if anything further. 4/25 purchase. 6/25 review.

2- 150 aH for use with trolling motor. It was a little longer than the old batteries I replaced, but that is OK. Also the terminal screws could be a little bit longer. Early user so have to wait to see how dependable they are. But I love the Bluetooth app. Very useful.

We’ll described

I've had the battery very long and it's done stopped taking a charge battery dead will not charge whatsoever. 4/6/25 after all the trouble I had with the battery I found I had to hook another battery to it for 30 minutes and it then would Charge back up this was on the 4/4/35 and it's still charging today 4/6/25 .

This battery has been running great for over a year without issues. It's situated in my greenhouse, which occasionally drops below freezing temps, but this battery holds strong, even with a relatively generic BMS system. Being LiPO, it's heavier than others, but the durability makes up for it if you're in a stationary installation.
