Miady 12V 8Ah Deep Cycle LiFePO4 Battery, 2000 Cycles LFP8AH Rechargeable Battery, Maintenance-free Battery for Fios, Power Wheels, Solar System, UPS and More

I use this Lithium 12v 8ah battery for a Canadian wilderness trip. It powered a Garmin 4 CV Striker the whole 8 days of fishing. We didn't necessarily fish all day every day, but I never had to recharge it. I fully charged it before leaving. It read 13.3 or 13.4 upon departure. I don't remember which. It only went down to 12.7 V at the end of the fishing trip. I did a lot of mapping of the lake expecting it to drain the battery but it help up, as I said, without having to recharge. Great little (light weight) battery for my intended use. I wouldn't hesitate to order any of Miady lithium batteries. Their prices are very cost effective.I also was able to carry it on the airplane without any trouble from TSA.

Battery came dead, 0.1 volts. Would not “wake up” as others have said. No instructions other than a tiny leaf of paper saying to charge at 0.1 C. Would not accept charge. Ball is in your court, Miady.

I use this battery to power a Xiegu G90 ham radio that has a very low wattage output. I can run the radio with its LCD screen for seven hours without a problem. I soldered Anderson Power Poles onto the tabs for quick connecting to 12 devices. I am very pleased with the battery. I haven't had it long enough to validate the longevity of the device or its long term Battery life, but for my low power needs, the size and the weight is perfect.

I bought this for use with a radio that requires only a few amps on transmit and only a half ampon receive. I get tired before the battery does; so far so good.

Update: After 1 year of light use, the capacity has dropped to 0.5AH. I wish I had the ability to test while it was still under Amazon's return window. I was somewhat concerned when purchased, but lacked the ability to fully test. Miady claims "18 months hassle-free warranty. 24*7 friendly and professional customer supports", but they don't have a warranty claim form at their web site, and ignore comments left at their contact form.First thing, out of the box - the terminals are not Faston F2 size, which is 1/4" wide. They are F1, which is 3/16". Now I have to go buy terminal connectors. So, it isn't a deal breaker, but Miady ought to list the correct terminal size, so right off, I'm down-rating them for failing in their listed information.
