Hello @Obrokoff , regarding the LTO batteries - very cool - allow me to throw some ideas out - just food for thought.

One of the frustrations(for me) of all traditional high capacity batteries is the universally followed rectangular "brick" shape packaging.
That fact forces one to mount the thing in only the usual under-hood engine bay location.
However, there are many unused spaces in the vehicle, which are a bit oddly shaped, and the traditional rectangular "brick" shape just will not fit.
On the other hand - by re-thinking how to package the individual cylindrical LTO cells - could they be mounted somewhere else?
Seems like a great opportunity.
Like underneath - in the several spaces between frame and body?
Or above each rear wheel well?
Or in a long tube shape, right on the floor, wall to wall, just behind the 2nd row seats?

Getting that battery out of the engine bay, and it's heat stress, and take the weight off the heavy front end, put it mid-ship...etc.
And - distributing the batteries around these areas - could allow increased very large total capacity - and yet without costing useful cabin space.
Anyway - you get my thinking?

There are many ways to make complete batteries

So these batteries are just for a solar or auxiliary power system?

My work is looking to get into batteries for energy storage systems (ESS) for stuff like remote towers for telecom, off grid solar stations (data storage and EV charging) etc so I've been soaking up a lot of battery info. The above link for the lithium titanate batteries is helpful too!
 
It’s a main power on Hdj80 twin batteries setup
No kidding?! Well it looks good, from what I understand the lithium titanate batteries have a very high cycle life, decent low temp function, they seem to handle a fairly wide range of voltage but might be a bit picky at the high end of charge voltage, and mediocre energy density. It sounds like they are a little costly, but maybe for a solar power storage system they would pay off in the long term. Might need a smart BMS tuned a bit for their voltage range etc.

Please let us know how they work out!

Yours is 12v or 24v?

30000 cycle of recharging, works from -35’C to 60’C, can give more power then AGM, calcium and other regular batteries.

I pay for 12 pieces 490usd, 20 usd for cases and 10 usd for aluminium bus.
Good quality 105D31R/L batteries costs about 230-250 usd in our local shop.

Price of titanate is not much more. But less weight, more power, more reliability.
 
Put batteries under the hood.
So little and so powerful.

I think two batteries in a left tray is a better way.

So. It’s amazing.
