Aims LiFePO4 battery

Was wondering if anyone has had any experience with this battery. It is on Amazon for 749.00 with a 10 year warranty. I have purchased their inverters in the past, but never knew that they made batteries as well. They have 50, 100, and 200ah 12 volt batteries.

I have an aims 2500 watt inverter charger. They were great on the phone so I would say call them and ask about their batteries. Generally, they sell retail on their own site theinverterstore.com so if there is anything less than legit about the Ebay thing, they'll know.

When everyone and their brother comes out with a product like this, it signifies the market for that product is in a bubble.

Right now, Renogy has a 20% sale on lithium batteries. So their 100am Lithium battery is usually $799, but with 20% off, it's $639..... Just wanted to pipe in...

I have an AIMS 12v 100ah LFP for my trailer. So far it has worked only ok for me. It appears to be the converter that’s causing the problem. It randomly goes offline when the converter is connected to it without being plugged into ac.
I’m still in the process of debugging the issue. Their tech support wasn’t really helpful.

Only 10 years? With so much competition around these well established brands should give 20 years warranty. After all, you can be sure that a brand like Aims or Ruixu or ShinBin will certainly be around and happy to replace your 10 year old battery in 2029.

Aims has been around since 2001 - so I think they may have a bit of staying power...

So, I just ordered their 100Ah battery. In the end, I made the decision based on their customer service and tech support. When I had an issue during my inverter charger install, they were great. (My fault a not theirs) It also doesn't hurt that their tech guy is into barbeque so he knows exactly what my goals are for the trailer conversion - just sayin....
Anyway, $749 for the battery is right within my means. I know I could have gone premium with Battleborn, but I'm comfortable with Aims. We'll see how it goes.

do they rate batteries like tires?

I tend to trash-talk Aims inverters because they're right up there with Xantrex for being well-known to over-rate their inverters and inverter-chargers... but we have 5 customers that I know of running their 200Ah LFPs in multiple configurations and all 5 of them are extremely happy with their performance over the past 6-8 months at least. It's not much for a long-term statement, but it's a start at least.

I'm guessing this is insider humor.... My apologies. I have no idea what this means.

As far as over rating their inverters, It'll be a long time before I get to a 2500 watt load so I may never truly find out. I bought bigger than I needed cuz I was hoping not to have to make this purchase again for several years.

Additionally, I tend toward brand loyalty as it has paid off for me many times before.

I received and installed my 100ah battery yesterday. So far so good, it was totally uneventful. I called Aims tech support prior to install for any last minute tips & tricks. I also asked if the battery's BMS had low temp cutoff. It does not. (the 200ah does) Since my EPEver CC does, its not that big a deal. The only issue I may have is if I plug in to shore power under temp. One of the main differences between the green Aims inverter chargers and the blue ones is less features. That includes a temp sensor, auto generator start, and there was something else... I forgot what. Anyway, If I'm gonna plug in, I'll have to warm the battery first.

Anyway, it won't be till the summer before I really stress the battery so no real review til then. That said though, I gotta say this:
I'm as good as the next guy with math and better than most. I can calculate a projected run time for a given load. In the end though, there's just no substitute for plugging my little dorm fridge in to the trailer last night and seeing that my system has kept it running over night and is still going. Yeah, I did the math. Nifty never the less. ?

Are you happy with the Aims inverter? I am considering one for a project.

A couple questions:
* Do you know if it marine rated?
* It looks like the settings only allow you to select the battery type...and you have to accept the profile for that type.... is that correct?

Let me first say that I over-bought, meaning that this inverter/charger offers way more than I currently need. I was kinda planning for the future. To that end, I have not yet really stressed this unit enough to get close to any limitations or deficiencies. What I have learned subsequently is that the difference between the Blue chasis and green chasis are some features that I may have found usefull. Specifically, the smaller aims batteries (50 & 100) have no cold temp cutoff. Thats no issue for Aims, as their blue chasis products have that feature in the unit, the green does not. The green chasis also lacks auto generator start. Consider these fatures before you select the product. For me, at the moment, I'm rarely plugged in. I'll make it through this winter with the Cold Temp Cuttoff out of my EPEver CC.
Regarding Marine application, I truly doubt it. I would call them though for the most accurate info.
Regarding battery selection, I cannot customize charge profile the way I can on my SCC with the MT50. I can't speak for the blue units. You'd have to call and ask.

All that said, my experience with them as a company has been basically positive. That's more important to me than stressing over individual features. If the product works as advertised and the company is reliable and helpful, I'm in and I'll stay loyal. My experience with Renogy was NOT that way so I moved on. For what woulda cost them 10 to 20 bucks, they lost the sales on ALL my current hardware. I digress....

I know there are lotsa people here who wanna argue specs, thats just not me. I want reliability and a voice on the other end of the phone.
So far, I have that with Aims.

That's a nice tidy setup BJ. Those fuses and bussbar setup look like excellent quality.

Thanks. I like tidy wiring.

do you have any input / experience with the AIMS inverter/charger and a LiFePO4 battery bank ? I have their 3Kw inverter/charger in my 5th wheel. I'm concerned with the absorption period being way too long and not moving in to the float state until after a long period. that dial on the battery switch is very difficult to use. does the current drop fast enough to quickly end the absorption period before any damage occurs ? or does it just stay on for a minimum of x hours ?

So, I never really thought to ask the question. Even though my trailer build is on going, my focus was more on the charge profile of my EPEver CC. I'm rarely plugged in. Like I described earlier I bought based on future expectations rather than immediate need. I have a 2500 watt Inv/Chgr with only one battery.
Sorry I have no real world data yet. That said, did you try their tech guys? I've had good experiences with them.

Brett.

I did get a response from their tech guys; I asked them specifically about having an absorption period of zero for LIFePO4. they said that there was NO problem with a long absorption time period. said it would not hurt a LiFePO4 battery. their bulk charge voltage is 14.4, their absorption charge voltage is also 14.4, and their float voltage is 13.6. the absorption period is a minimum of an hour and a maximum of 12 hours. It is a multiple of how long it took to get to the 14.4 bulk charge voltage. so it just kind of substantiates my original thoughts that their charger is just a modified lead acid algorithm. it doesn't take anything in to account for a LiFePO4 battery.

I think that this is true for a lot of "Lithium capable" chargers. It is easy for them to have one profile with adjustable parameters. This is ok as long as they give you enough flexibility on all the different parameters. The absorption time is one that is often not very adjustable. Being able to disable the equalization cycle is a must.
