Has Anyone Had Any Experience With Ezeal Battery Company?

[White Lightnin']

I was searching for batteries and found the Ezeal Battery Company in Houston Texas. Has anyone on this website had any experience with the company? Can anyone tell me of any experience they have heard about?

I've copied the link below from the batteries I found. The company information can be found at the bottom of the page.

Never heard. No link...

It would have been nice if I'd included the link I promised. I'm not totally accustomed to Apple computers.

They sell the same EVE 230Ah grade A EV cells that I bought from Amy in china (docan).

Mine were 651 US dollars delivered.
$55 each, plus shipping.
Good cells. Mine all measure 244 to 245Ah. And low impedance look perfect.

How are you getting by with four in a series?

Ordering these batteries fro Docan in China will give a price of $69.00 each.

Ordering them from Ezeal gives a price of $81.36.

Why I was thinking six I ill never know.

8 lifepo4 = 24V nominal ish.
7 lithium ion, lipo, etc. As long as you dont mindthe odd fireork display.

Both end up a little higher than lead volts but acceptably so.

Will the EVE batteries handle going up and down hills without suffering any damage?

[Burgerman]

They can.
They are capable of 1C continous. So 230A for 1 hour.
And intermittently, for a few seconds more...

Maximum Instantaneous Discharging
Current 3C 60 seconds (thats 690A!)

If your chair took that much the motors would turn to smoke after a few seconds. It can only maintain 120A for a couple of seconds before the power module rolls back power.

What is used to separate the cells? Do they need to be separated?

[Burgerman]

They need something extra as well as the blue plastic sleeve they come with for safety. It need not be thick. Just abrasion resistant.

A 1mm fibre plate comes with them from docan.
I wont use that, it needs something under it too, and around the perimeter.

So I will use a roll of duct tape, and plastic sheet card or these:

I have a couple of $10 - $20 multi meters in the tool box in the garage, but I have a feeling they are not be accurate enough for what I am wanting to measure. Can anyone tell me of a Fluke meter that will make the measurements I need that is not overpriced for what I am wanting to do?

I went to the Ezeal website today and bought batteries. Including the roughly $80 shipping charge I paid about $73.00 for the batteries. I could have waited to get the batteries from China, but I have no idea what tariffs may be applied by then.

I need to get wire and a fuse yet and I can think about getting the batteries put in the chair. Unless I am overlooking something. Can anyone tell me what fuse I need to install between the batteries?

[Burgerman]

I always use midi 150A fuse, at the plus end or the centre between cells 4 and 5.

In fact I am considering adding 7x 200A fuses - one between each of the 7 cells in this new pack. Cant face building it at the moment its too cold and stopping in bed. Will happen in the next week or so. Then go into the salsa.

But 1 is enough really!

If you are charging with a ZXD and a hobby charger, then the ZXD is as accurate as you can need for that job. Just connect it as a volt meter.
If you get a fluke or any meter just be sure its accurate. Some of the cheap flukes are not. I have one thats about 0.1V out...
I also have a expensive 289 which you do not need (me either!) but I get that calibrated with certificate by fluke every so often. Its the one I trust!

Close enough!

Still overkill.

[White Lightnin']

Shirley, I appreciate the reply, but I haven't the faintest idea about how I'd go about ordering it. Thank you!

Search for its name

Its not cheap, good meter though.

I bought flukes best meter. USED in the US for around the same price, which is a quarter of its retail price. Then sent it in with a fault, lifetime warranty. They replaced it wih a brand new one...
Heres amazons crazy price... https://www.amazon.co.uk/Fluke-289-True ... B51HI?th=1

I suggest you probably dont need to spend more than 40 uk pounds for a good meter. Mine is complete overkill. The UNI-T one I linked also too much. You might get the same one for half that on aliexpress for e.g.

E.G
https://www.aliexpress.com/w/wholesale-ut-61e.html

UNI-T, Fluke, Brimen, etc all make good meters.
The reason people buy fluke isnt accuracy its because they never change the design... Take the miliatary, they train their guys using a fluke xxx and then they know how to do x job. They want that same meter ALWAYS. So they dont have to rewrite 5k servive manuals for a tank or an aircraft.
Same in industry. Its about standardization across tools and processes in big organisations where a different meter throws a spoke in. Plus they have lifetime warranty etc. And silly pricing...

U61e+ sells $
62 here.

I can order one, and ship it together with ZXD & PowerLab 8.

Be quick. Your parcel is scheduled to part tomorrow.

[White Lightnin']

Shirley, thank you, but I ended up buying a Fluke. The decision was a matter of logistics. The repair shop is only about 300 miles away vs across the pacific ocean. At one point I lived only about 12 miles away from Everett, Wa and my leg shop is still close to there. I will get near there from time to time. I sure appreciate your offer.

[shirley_hkg]

That's fine, absolutely.
