DC HOUSE 12V 30Ah Mini LiFePO4 Lithium Battery, BCI Group U1 with 30A BMS, Low Temp Cut-Off, 4000+Deep Cycles Perfect for Fish Finder, Trolling Motor, Kids Scooters, Power Wheel Chair,Boat, RV, etc

With my latest set of AGM batteries already not fully charging after only about a year, I decided to convert my eWheels Bugeye 3-wheel scooter to LiFePO4. I chose to use 4 of these in series instead of a single 48V cell because these are drop-in replacements for the 4 standard AGM batteries. Since a meter designed for lead-acid batteries isn't accurate with LiFePO4, I chose to add this meter: https://www.amazon.com/dp/B0DBVRGFT2. Rather than measure voltage and estimate the remaining charge, which isn't very accurate with LiFePO4, it measures the actual current and calculates remaining power based on the capacity you set (30Ah, in this case), so it's very accurate. It said I was down to 3% when one BMS shut down, so that seems to indicate the stated capacity is spot on. I also went 32 miles where I could only go 20 or so on a new set of AGM's, so that seems to confirm it. A bonus is that the voltage holds up till somewhere below 10%, so the top speed doesn't decrease as the battery discharges.I chose to use this charger: https://www.amazon.com/dp/B0BGMCL1L7 (for all 4 in series). Being only a 3A charger, it'll take 10 hours to fully charge from fully empty, but I rarely will be getting even below 50%. And I could re-use the existing charge port without worrying I might be exceeding it's current capability.

This is my 2nd or third product from DC House, I bought this to replace a riding mower battery (it basically would energize the solenoid and power the lights) but unfortunately, it doesnt fit in the battery compartment so I will have to use it for something else. I might replace a 20 AH battery in a homemade portable power station I use for camping to charge lights and phones while off grid. I was able to use it during a storm that had knocked power out for a few days and it definitely held its own. It came pretty well charged but I have a LiFePo charger that I hooked it up to and it was fully topped off after an hour or 2. Readings all came back in spec and is still holding strong. No issues so far. This was a test of the brand to see how I like them. My goal is to get a couple of the 48v 50ah or 100ah batteries for a solar system I am in the process of putting together and I wanted to check the brand out, so far so good

I have two of the 100ah batteries and they work fine so I got these to make a portable power source. Just like the big boys these are working out well also. Very satisfied with them.

I bought these batteries for my Jazzy Elite mobility chair. They came charged and ready to use. The price was very reasonable. Exactly as described. Highly recommend.

Excellent quality battery. It is super lightweight and runs my air bubbler all day!!

Good battery for the price does what it’s intended for

I would have loved if These were 1/8 thinner then I could fit four in my scooter to really improve its range

I know they aren't rated for this, but I'm using it for a 80s motorcycle.Cranks just fine.If you pull a dumb and leave it in gear when cranking the overdraw protection works great, just cycle the key and it gets power back just fine.
