ECI Power 12V 5Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery | 2000-5000 Life Cycles & 10-Year Lifetime | Built-in BMS

I have several of these batteries that I purchased off Amazon. The last one received was missing the terminal bolt and washers. I contacted the company about the issue and they replied within several hours (I was impressed by that) and apologized that something was missing from my order and they would send replacements out. 2 days later I had a FedEX envelope on my front stoop with the missing hardware! WOW! Not use to that!Now that is service!I use these batteries everyday from Cellphone power to Deer Cam in the wood (last about 2 months) . Never had an issue with the batteries. Great stuff.-Doug

I was quite surprised at how light in weight these batteries are compared to the deep cycle batteries I was using in my boat. I'll be buying two more for my smaller 12' V-bottom boat. The smaller boat I have to really watch my weight as I load the boat and when I'm on lakes where I can only use an electric motor, I've had to lug a heavy deep cycle battery, These batteries were so light I carried 2 of them down at a time to my pontoon boat. I use one for the trolling motor and one for the anchor winch. I've been using them all summer so far and it's not died down as a regular deep cell battery would. I even had a problem one night with the gas engine not starting and I had to use the trolling motor to get the 24' pontoon boat back to dock. I would estimate that I've used the trolling battery for about 18 hours so far and it still powers my trolling motor as it did when I had it fully charged. I did read that I could hook the two together in either series or parallel, I suggest reading up online on the advantages and disadvantages of both hookups. Next summer I think I'll buy 2 more and hook 2 in parallel to each of my devices and see if I can make it through the summer. I also thought about getting a solar panel to charge the batteries, that way I wouldn't have to worry about taking them off the boat till it's time to store them for the winter. I'll update you on how they handle solar charging once I do that. The only drawback that I found was that you have to use electrical terminals to make the connection as the terminal posts are too small for conventional battery cables to hook to.

It fit in my loadtrail trailer electric brake battery back up box by bright way group

This Battery is very well designedI been using it on Ranch solar Ghost Gate openner lasted approximately 3yrs with no issues

This battery worked really well until the warranty ran out after about 14 months of service. The battery would no longer charge initially I thought this was a really good product. It did what it was claimed to do but with an only lasting 14 months, I just can’t recommend it anymore The company would not even give me a partial rebate or do anything on a refund.

Fantastic batteryGreat battery for the priceHolds charge wellGreat replacement for Non lithium batteriesUse it in a scooter daily with 0 problemsBig power improvement over nicads

Been running the 10 AH battery for 2 years now on my Garmin 73 ice fishing bundle. Battery lasts 3 times as long as Garmin battery. My brother in-law bought one for his Humminbird Helix 7 his lead acid would last maybe all day fishing. This battery lasts 3 days and we are fishing all day long with them on LOTW in baudette.Lighter and less money.

I bought 2 at the same time. One was DOA. But the one that works is pretty good. I would say that the build quality is lacking but it is lightweight and has worked perfectly the few times a day.
