Lithium Titanate (LTO) questions for a new guy

[MarkM101]

Hello all,
I'm running a very basic solar setup in my car/workshop trailer. 150w solar and 4 flooded batteries. My question is about the lithium titanate batteries. Can you charge this type of battery below 32F? I am really digging the cycle rate and just want some opinions on a battery bank built out of these batteries. Also helping a buddy setup an off grid cabin and plan to have about 800w of solar panels running in a 24v configuration. He has a 3kw military diesel gen as a backup. Inverter for this cabin is a Iris 1800 quiet power military 24v inverter. Thanks for your help.

Yes ..... the LTO batteries have a very wide temperature range tolerance. They are good down to -40 c .... which is also -40 F.

Typically they can handle a 5C charge rate and up to a 20C discharge rate and a huge cycle life ... these are pretty amazing cells.

The drawbacks are that they are more expensive than LiFeP04 and they also don't have as good of energy density.
