LTO battery

Mr. Pink said:

I was just watching your battery monitor (half an hour ago) and noticed that the PV voltage dropped periodically every 10 seconds. Am I correct that this is the charge controller probing the PV output?

Hi. Is it possible to use 6s lto yinlong to start a 12v diesel truck engine? I'm tired of buying lead acid batteries that are unusable after a couple years. The amps required for starting a diesel is crazy high so i wouldn't want to damage the lto batteries. I think the lto yinlong have 10c discharge so at 40ah that would be 400 amp max discharge.

So maybe i would need to have a 6s4p lto which would give a max of 1600 amp max discharge. Or I could use a maxwell esm supercapacitor alongside to help with the burst of amps that are needed to start an engine.

Thanks for your input.
Don.

Im experimenting with LTO batteries so far I like them but have not capacity tested them yet 100% I'm using 12 batteries which gives me a low voltage of 1.6v per cell and high of 2.8v per cell with a total range of 19.2 volts to 33.6 my plan is to cycle them them fro 20 Volts to 33 volts from my testing so far that high end of the charge does not yield that much energy. Currently my inverter works from 33 volts down to 21.4 volts but I have found one or two with a range of 18.1 to 34 volts so they should be perfect. Im just want to do some more testing before I shell out 1500 on the inverter. Most other inverters dont have a range optimal for LTO batteries.

Im working on a testing rig to get full DOD out of batteries and I will report my results hopefully with a full energy per Mv drop in voltage. If i test these and they get close to 40 AH I will use these batteries in my systems. I want to use them because of the high C rate and numbers of cycles possible. Plus I just like trying different things.

The way the math seems to work, 11 LTO cells would put the voltage ranges closer to what inverters expect, at least at full charge, than 12. I have zero experience with this though. I'm assuming a 1.8-2.8v range for LTO. Would I find more 24v inverters available using 11s instead of 12s?

I think they would work fine. Planning a test on my gas truck. Not diesel but I will be able to hear if it is weak.
