Another great review Jason. Where do you stand on connecting two of these in parallel vs. getting a 230ah battery like the Litime? It would be used for mainly powering 12 volt lights and fridge in our camper and possibly connecting to an inverter for powering hairdryer or coffee pot or emergency home backup. Thanks

Thanks Jason, another excellent review. Very timely as I have a upcoming project that will need batteries. Thanks!!!

[@user--PM]

nice review on this "cheap" battery, and yes there are a bunch of them out there. i can see by my price tracker that this unit has had a previous high price of a hundred bucks more, if they sell well from your review i wonder how long that price remains low. anyways thanks for the video. hope you enjoy your toy hauler you customized.

[@Jasonoid]

The price tracking is interesting on Amazon when there are multiple options for a listing. This battery is brand new so maybe it was a different option? I don't think the price will ever be going up to $300 again.

[@RanchoTexano]

Great review and cool trailer build!

[@RanchoTexano]

I may finally replace my RV LA batteries now!

[@OnusBones]

Very nice. Some kind of camper / trailer build will be one of my earliest projects when I retire (possibly late this year). Having a couple of these batteries on hand is probably a good idea. I shot this month's wad on a portable AC unit (not 12V, but only needs 700W), but next month is certainly a possibility. Another Licitti box for one might work well too.

[@davef.2329]

Thanks for the great review. I went to buy one, but there was no provision for using the discount code there. Will check it again later to see if they've updated the site. Nice work on the trailer, BTW. Cheers.

[@Jasonoid]

When checking out on Amazon, you add the discount code under the promotions section. It's kinda hidden.

[@jerrytalley802]

Put a small window in that gives light but not big enough for them to break in. Thanks

[@Jasonoid]

Thanks! Good tip

[@posteroonie]

Eve, like all other cell companies, unintentionally produces some grade B cells which leak onto the market and are presented as grade A's. Many discount battery brands put true grade A cells into batteries that they send to reviewers, but use grade B's to lower costs in the batteries that they sell to regular retail customers. This is fine for light use because issues typically show up in 2-3 years, well after the warranty period, and who puts their battery through a full charge/discharge cycle every day? Recycle the battery since prices will be low enough in 3 years to replace it easily. Because the grade B's don't balance well, and have different voltage drop under load, the whole battery loses effective capacity more quickly than if it were made with grade A's. Prices are so low that I'm not saying that these cheap batteries are a bad deal; the quality batteries have to be about 70% more expensive, it seems.

[@Jasonoid]

Wouldn't they destroy the QR code and battery SN if it was a grade B battery?

[@posteroonie]

@@Jasonoid The QR code, at least the few I've seen, are just the SN. What I don't have access to is the manufacturer's data on how that cell tested out at the factory.

[@adriftatlas]

I remember Will Prowse saying that some of the discount brands will vary the BMS and cells that they use over time. So while a battery bought today may have a good BMS and cells, a battery bought tomorrow may have a poor BMS and cells. I believe there was a video where he compared the contents of a battery sold a year apart and it was different.

[@davefroman4700]

What ever you say Agent Smith....

[@jerrytalley802]

That looks like a well made battery to me. I’ve never seen these but Redodo is very reasonable and 5 year warranty, so unlikely they do bait and switch

[@overland63]

One thing I see ignored on a lot of these lithium battery reviews is any mention of their limitations in cold or hot conditions. The low temperature cutoff is cool, what what does it really mean? Is it safe to still leave the battery in really cold temperatures? Would be okay sitting inside your truck or SUV interior in the winter as the house battery, waiting for the vehicle to warm up inside? Or would that damage the battery? Not everyone lives in a temperate climate. Love your channel. Thanks for everything.

[@Jasonoid]

I live in a high desert so I have very hot summers and very cold winters. Yes it's fine to leave the battery in cold temps, it's also fine to use / discharge the battery in cold temps. The only damage that will occur is charging LFP batteries in cold temps. That's why low temp charging protection is in place on these 👍

[@overland63]

@@Jasonoid Thanks.

[@Kantuski]

@@Jasonoid My question as well, at what 'low' temp will charging a LFP cause damage? I noticed that the manufacturer claims a 5 degree F as their low temp cutout, wouldn't that be 27 degrees too late to provide protection?

[@Jasonoid]

5F is the setting in this model. From my testing, when charging at low temps, the battery voltage jumps quickly to 14v making the BMS think it's full. So you can't really put much current into the battery anyways. If it's cold you can only charge it very slowly at low current which won't cause damage.

[@Kantuski]

@@Jasonoid Thanks. Is low temp protection to stop the ability to CHARGE only or also to stop the ability to DISCHARGE? I have read there are 2 settings for protection and charge was @ 32 F while discharge was @ 5 F, like this spec.

[@RicardoCervera-l7d]

You know I love your videos; can I just swap this out for an RV regular battery, or two, without needing anything else?

[@Jasonoid]

I walk through that 'swap process' in this video: kzbin.info/www/bejne/fHS7p5iwpJ6fiq8 You can use any of these batteries to do this.

[@NatureZone101]

Thanks for the review. Do you know if that "5 yr service" is actually a 5 yr warranty or if it is just a tricky way of not telling us what the warranty actually is? Did they mention anything about that to you? Thanks.

[@beverlyheatherdale4898]

[@Jasonoid]

[@kevinholland4156]

Jason, this would be a good "Perk" incentive. To have a battery spreadsheet would be awesome; like you have nothing to do in your life but to build another spreadsheet.

[@ericklein5097]

I am a little concerned by seeing battery voltage down to 13.0V at 10 minutes...3.25V per cell with a 20A load...I'd expect to see 3.28V or so...but without measuring on the battery terminals its hard to say if you got that 160mV of voltage drop on the cables you used (which seem plenty large) Seeing 12.40V with a 100A load seems about right 3.10V per cell at 1C is where most LiFePO4 falls. I guess the cells are beyond the 6 month "shelf life" and very likely ARE NOT Grade A cells. Would love to see a YR1035 or RC3563 used to do an IR measurement....the test reports from EVE are VERY consistent so its pretty easy to know just off IR if a cell is Grade A material

[@Jasonoid]

Thanks, I'll look into that 👍

Do you have to upgrade your converter on a 5th wheel RV when switching from AGM battery to this battery?

[@Jasonoid]

I did a video talking about that here: kzbin.info/www/bejne/fHS7p5iwpJ6fiq8

[@rhiantaylor3446]

I guess the main issue is confirmation that you are getting grade A cells. Ideally, when it was apart I would have wanted to fully charge battery to check the top cell voltages and then discharge to check that individual cell voltage trend towards the lower limit at the same rate showing that they all have the same Grade A capacity.

[@ericklein5097]

Almost certainly not Grade A. Selling this thing for $200 means they would lose money buying Grade A frome EVE

[@minceym]

Hi Jason another great video. I was in the market to purchase another LifePo4 100 Ah battery to use with my PECRON smart charger. I currently have a LiTime & WEIZE LifePo4's which are still a little pricey. This seems to be a good option. Jason I have one question, why when I charge these batteries at 14.6 and after the battery is fully charged. I disconnect the battery. And after a little while later, I check the battery voltage. It always between 13.4 or 13.6 is that what it's supposed to read? Thx!

[@Jasonoid]

Yes, it's completely normal for LFP battery voltage to 'rest' at 13.3v - 13.5v after being fully charged. It won't ever stay at 14.v very long.

[@minceym]

@@Jasonoid Okay thank you, I thought the battery was going dead. I'm going to purchase this battery. I was trying to stay with the named bands. But it looks like things are changing. Thanks again for helping me with my journey using Solar, Power stations and batteries. Stay Blessed!

[@AbstonsGarage]

So with this BMS you are able to see each cell correct? Some of the other LiTime batteries do not show the balance info or cell info.

This BMS is 'dumb' , no smart app connectivity or anything. It monitors everything on its own and theres no visibility.

Hi Jason do you have any instructions on making that inline battery shunt? I've been trying to place one inside my licitti battery box. But it won't fit. Any help would be greatly appreciated. Thx!

[@ericklein5097]

Looks like he copied the idea from David Poz who has a video on it. Just to let you know he found out his shunt was 7% off so he has to multiply results by 1.07. I would suggest using something else to calibrate the results too even if its just taking several multimeter measurements of current and voltage throughout a discharge

[@minceym]

[@jeffreyumeh8580]

@@Jasonoid Honestly though if you only want a 12V battery though I think building your own battery is not a bad option if you are going to use EVE cells, because it's just 4 EVE cells in series, I suppose the only issue will be the cost of shipping on the EVE cells, because when your ordering like 16 the shipping is actually pretty cheap, that way you know what cells, BMS and wiring your getting for sure. And as long as you get EVE cells that are pre-tapped all you need are some bus bars which you can lock down with nuts, although again it's not like you are going to save much money though, but if your really that worried about getting a high quality product it's one way to guarantee it.
