Anyone willing to share a good LTO supplier?
#1
I am looking to buy 100 LTO 40 or 45 Ah cells.

I need to find a supplier who is known for providing good cells
so I don't have to mess with shipping them back.

I also need a way to test them individually.

I was thinking about building 6S 12 volt packs
and stack them to get 48 volts.
Probably use 4 in parallel to get a total of 6 x 4 x 4 = 96 cells

I was thinking
- I wouldn't need a BMS if I can get I can combine cells with similar internal resistance
- I would add a balancer to each 12 volt pack.

Is there anyone on this forum who is willing help
a newbe who is trying to DIY some LTO battery storage?

Anyone?

I reached out to Craig, but he wasn't willing to share his supplier because
"I literally spent over a thousand dollars trying to find a good one".

Gonna be tough finding LTO cells, especially if you want new ones.
Any specific reason why you want/need to go with LTO specifically? You could go with LiFePO4's and get pretty close performance, and cheaper overall in the end.


btw, your link goes straight to a login page (at least for me)

I'd be OK with lightly used ones if they meet specs.

I want LEO'S because
- they last forever (at least longer than me)
- they work in any temp
- they are practically indestructible (you can under charge them to zero or over charge them without destroying them)

The only negative for me is the weight, but I will never move them once in place, so that is not a problem.


Thanks for replying.

I'm building packs for remote off-grid, that need to be reliable.
So we've been getting cells from suppliers that sell them to car stereo enthusiasts.  Showtime Electronics is one supplier.
They're XS-Power rewraps of 40Ah Yinlong, not brand-new but still decent grade cells. 
If you want to get in on a group buy, get on the facebook group 'yinlong only'.

LTOs had a problem last time I checked: high self-discharge rate.

They have very, very low self discharge. I have had one stat on a shelf (shed) for a year and it still had the same voltage....

My supplier was in China - check my build thread, they are listed but I can't remember them off hand at the moment.
If you can't quantify how much they cost, it's a deal, I'll buy 5 of them for 3 lumps of rocking horse ......
