Quality is fantastic! My old one died and I didn’t realize how bad it was until I got this one. It has more power and lasts a lot longer than my old one! I also LOVE that it’s lighter!

I was looking for a 50ah lithium battery to power a few electronic on my boat but didn’t really want to power them from the same battery because I read this could cause interference. I ran across these in the 2 pack while looking and figured I’d give them a try based on their reviews, price. I’m running a Garmin 94sv Echomap UHD Chartplotter and a NMEA 2000 network. I run both on their own battery and could not be happier. They are very light weight and compact so they fit under the center console of my boat perfectly. I can run all day (about 8hrs) and still have power left over!! Very pleased so far.

Haven't had it for long yet, but so far it's working fine for an electric Power Wheel kid car. Feels good quality (but surprisingly lightweight, like most LiFePo4 batteries, when you're used to SLA).

Great! Very long lasting and good capacity.

I purches 2 of the 16Ah battery to use for external power to my tactacam trail cameras. I chose them because they are much smaller, lighter, and work well in lower temperatures than lead acid batteries. I have not had a chance to use them yet but I will update this when I see how long they last. One thing I did not think about is that you will need a charger made for lithium batteries. Luckily I already have a NOCO Genius battery charger that can charge them because a normal lead acid charger will not work properly. So far I really like them but I need to see the performance before I can give it 5 stars.

Good price

Excellent quality product. There is no cover for the terminals making it not 100% waterproof. Batteries have been installed in my golf cart for over a week and the kids along with myself have really been putting them through the ringer lol. Batteries are light weight; study crafted and hold a great charge. Wish I would have bought these sooner!

Update,Battery is great. Further testing revealed my charger would work fine when connected but quickly goes to a dead short.The charger was draining the battery until BMS cut out.Battery is fine!Was thrilled with this battery until it refused to charge after about 20 cycles. Not sure why but BMS cuts out while trying to charge it
