or this .....

I'm not in a hurry. But can order anytime, whatever works for you. Thanks!

That CATL turns out to be a 70Ah cell only .

Seems what Gnomatic has been chasing after are better better picks .

Or this 80Ah one , @£22.00

They are ALL from the seller who SNAKER purchased from .

[expresso]

thats a good size -- would fit easy in my box width wise - just a bit taller - but will work - i make it work

if you are up to getting some for me - - i leave it to you which is best cells - 80ah would be great -

what your showing is in pounds or liters ? cost of each cell - etc.

these are NOS ?

These EVE-LF90 has many sources to choose from , even brand new from factory , mostly NOS .

They are 36mm thick , but a bit shorter .

It will be only one foot wide for the entire pack . Think again if your P220 why can't carry it .

Right now I''m torn. I like those 75ah cells I've been looking at. In part because they are easy to fit. I could put them in their own enclosure and set enclosure in my battery area. The cells would be well protected. My battery area has several slots and openings to the outside of my chair. So with these cells its easy to have a well protected pack, and still a 150Ah pack is pretty darn good. Snaker likes his!

The EVE-LF90's are very tempting though. 180Ah. Insane. In the winter I could go two weeks between charges. But space is tight with those. And if I give them their own enclosure for protection I feel they need with my battery box and all its gaps and holes, I'd have to mod my chair, no getting around it.

I was not considering them for the full chair pack inside the P222 - i have lead in that chair only with this 60ah ADD ON i just put on -

i was thinking of making Another ADD ON - for my new chair i should get in sept. - its the bounder - and will have 100Ah lithium in there already - i was going to add another ADD ON to that chair -

36mm thick makes things harder - it may fit but i dont know - to pack it well etc, - i know for sure 30mm would be great - and fit easy - the Cell Genomatic picked would be good also - the height is the other issue for me 200mm and under would be easier for an ADD ON - and in the chair -

hard to decide -

[expresso]

i guess i have a few options on my end maybe - i can consider maybe doing a full pack in the 222 chair - but i am worried concerned about that - the lay out and taking the chair apart etc, is much harder for me - would need to make two 12 V packs or 2 24V packs and connect - balance wiring seperate etc, never done it this way
would be my first - so a bit more planning involved

then i would need 16 cells - instead of 8 - have to think it over good - they have to fit in a MK 24 size - i cant do any modifications -

its tempting but unsure if its worth it for that chair -

[Gnomatic]

For your add on, 36mm * 8 = 288mm or under 11.5inches. Is that too long for your add-on box? If so, the cells below may work better

75Ah, gets good reviews, 195mm tall

The cathode/anode and a diagram immage is on the data sheet.

Heres a diodes for dummies page https://www.dummies.com/programming/ele ... ts-diodes/

Put the positive from your lithium battery into the flat part of the arrow if it helps! Thats the anode. But just think of it as an arrow. Your lithium positive goes to the spiky looking connector... on your diode.

Yours is inconventionaal looking, and heady duty, and to work at high amps such as ramps or steep hills, it may need a heat sink. But for normal use, the heavy wires, and ring terminals should be adequate to lose the bit of heat it makes.


Getting it backwards wont hurt, but the lithium wont do anything. Its as if its not there. No current will flow.

Ok when i get it - i will post a pic of how i would do it and then you let me know if its correct or not - the arrow part would be then facing my ADD ON pack wiring - you say Use Pos. - would Neg. wire be the same effect and safer for some reason ?

75Ah, gets good reviews, 195mm tall

yes its too long - its not long by much but after i added in the silicone between the cells etc, and packing - this is why i had to extend the box some -


i dont mind those 75ah Cells either - - in order to make it fit with out me having to cut it and extend it - 30mm would be best - i can wrap it - pack it and still drop right in without me cutting it up to extend it - makes things easier for me -

195mm height would be perfect also - i may be even able to close the top lid - thats what i would like - but worse case i can deal with a bit taller - not much but this time around i rather have it 30mm thick each cell

i may just do 8 Cells - thinking about taking my chair apart to get inside etc, - i dont have the help for that - chair is fine with the lead inside and 60ah ADD ON now - so this can last 5 years this way easy i think - may end up just being indoor chair by then or sooner - and will be my back up to my back up chair once i get my new chair -

i do want to add more lithium to my new chair also - and 75ah or 80ah - as long as they fit 30mm or maybe 32mm max width - and 200mm max height with the posts - between 190mm and 200mm i think can work fine - if you pull the trigger on them - i be willing to tag along with 8 also - it possible

[Burgerman]

Its super easy. Impossible to get wrong.

t wont make a vast difference, about 0.25V OVERALL.
But 2 in series, or a Silicone based one would. But you dont want to use the lead hard?

So when your lithium is down to 3.1V per cell, the lead WITH the diode will be 24.55V instead of 24.8V.

So your lead battery will each be 12.275V instead of 12.40V. Its about 10 to 15 percent of the lead charge.
Your volt meter will drop faster, dont let that confuse you!

If you did it with a silicone diode, your lead would be used down to about 12.05V or about 80 percent approx at your 3.1V per cell liuthium end.

You are collecting lithium packs faster than me!

[Gnomatic]

Yeah, I'm thinking of going for it. The 75Ah ones, because I KNOW they will fit any of my chairs easily without modding anything. 75Ah for an addon is pretty massive.

150Ah pack made from those cells would give me 67% capacity increase over my 90Ah pack for my chair. Plenty for a long run.

I got the one u linked to. Yeah I rather keep the lead to last longer so I don't have to replace them I try one when I get it. U have. Link to the silcone diode also just in case. Thanks it's even fine the way it is really. I mean 30 miles !! It too bad as my last resort chair. I needed this 60ah done fast. Or else I be. Very limitined And it's summer

I mean it's not too bad

[Burgerman]

Even if you dont use it, its very hard going back to lead. Or rather lead alone in your case. Even new lead bricks seem pretty dismal after having had silly lithium range capability. Its not so much about "needing" 30 or 50 miles of actual range. Its knowing that its there. So your range anxiety goes away. Someone asks you to a BBQ in the evening, or ddown to my grass airfield at 8pm for an hour, and even after a busy day, you have no fears of not making it back home. No matter what or where you end up.

And like last night/today, my carer forgot to plug in my charger power supply to the wall. No power. Couldnt charge my chair. And yesterday I went miles to the optician in town, and then spend the rest of the day fixing my garden... Seeing is nice! So had I been using lead, I would have been pretty much screwed esp if I was a normal user.

As it is, no problem. Lithium easily does two big and busy days. But even my lead Osyssey BM1 chair can be charged from 100% dead to 90+% full in JUST 40 mins. By my van at 100A as I drive somewhere. OR in the house in just 1.5 hours or less by my 40A/50A bench chargers or power supplies. I got that covered either way.

[Gnomatic]

Its not so much about "needing" 30 or 50 miles of actual range. Its knowing that its there. So your range anxiety goes away..

This is true on a couple fronts. 1. With lead bricks alone, you just have a lot less range than lithium. Period. 2. If you're maxing out your lead bricks and cycling them deep on a regular basis, they die a fast death. So you limit your range on lead even more to baby it so it might last 6 months.

I will never go back to lead alone - - and from now on - my ADD ONs will be 75ah - nothing less will do after seeing how this 60ah is working - i feel much better now and dont feel limited to go out - i can go far and not worry as much -

i was actually trying to achieve 36 mile run round trip - i am a bit shy of that now - if i take the city bus one up to end - i can then make up those miles and make my trip - may give it a try tomorrow - either it works or i will kill my pack trying to get back

Bad news . Those cells are gone . Can't see any good picks from Snaker's seller for the time being .

[Gnomatic]

Crap. Those seemed to get excellent reviews. However, I'm not in a hurry, so will wait from some more good ones to turm op. Thanks for checking.

[shirley_hkg]

MEANING that you can fit 210Ah in place of lead, provided that you have JUST 4MM mm extra width available over a grp24 battery.

The math:
Cells are in mm:
130.3
37
200

37 x 8 = 296
37 x 4 = 148

We have a 240mm tall box. With 260 (or more) x 340 (or more although this way not an issue)
Arranged as
||||||||
||||||||
2 side by side is 260.6 (plus 3mm insulation from 1mm sheet so 263.6 total)
8 deep gives 296 (plus 9mm insulation so 305 total)

So with careful measuring it might just fit 16 cells.
210Ah in place of 74 (45 to 50 usable) So 5 to 6 times stock range. For £512

HOW MUCH will this cost to ship to UK in pounds for 16 cells and a huge 210Ah pack?
Thanks!

Air freight : £6.75 / kg to UK ; custom fee included . No more extra at all . That's what I've been told.

EVE-LF90 , Rated --- 3C (5C max) ; IR @ 0.5mΩ .

90Ah cell , NOS @£27.50

* * * *

EVE-LF105 105Ah * * * * 2018 batch NOS @£32.00

Any guinea pig ? ? ?

Found a reliable source ( refundable ) of EVE-LF90 cell @
£27.00

Will get myself a set .

BM are you still insist the 105Ah one only ?

[Burgerman]

Not neccassarily. But still need to measure and cant yet to be sure.

[ICEUK]

Shirley what r the dimensions and any additional info?


Thx

Depending on the size - and weight of the Cells -

i may be interested if it fits my needs for 8 of them possible -

thanks

We are doing a 2P8S pack .

Is it still save enough to eliminate the insulator between cells of the same group ? It will save 4 insulation sheets in a row then , ie another 4mm in length .

Hope it helps .

I really like the size of these cells and how small of a package they end up being for such capacity. Having all the terminals on one end is nice too. I hope several of you do builds with these, with lots of pictures for us mentally challenged individuals
