LTO batteries

Hi all,

It looks as if LTO batteries are becoming available.

I've written to the company below for pricing on a 100 amp-hour nominal 12 volt battery.

They can be charged at 10 C. (i.e. 1000 amps)

They work from -50 c (-58 f) to 60 C (140 f)

The cycle life is 30,000

Assuming a 100 amp-hour jar:

They can be drawn from at up to 10 C (1000 amps or 12000 watts)

They can be drawn continuously at 3C (300 amps or 3600 watts)

It seems to me that they would be a great choice where battery space is limited.

from OSN POWER

Anyone know much about them?

    Since they are rated to 10° F and use with "electric skateboards"
    I would make sure they are "Thunder Proof"

    I'd also ask about the physical size of a 100 amp hour 12V battery. Since it appears that the energy density is close to 1/3 that of a standard lithium battery, it may be impracticably large.

    FWIW, I came across this link:

    Some are not as specific but I think the primary use is for start batteries due to higher discharge rates and low temperatures.
    But seems OK with deep cycling.

    I am curious about how the start batteries and alternator work together.

    An ‘independent’ (objective) white paper would be useful.

    They do make LiOn and LiFePo4 but LTO is a different battery.

    I would be very interested both 100 AH and around 24AH prices.

    Also charging specs. if the OP can respond when the company gets back with them.
