Hi All, I would appreciate some advice as to how to go about selecting a BMS for a performance EV application. We are looking at building a 320V pack using LTO's, should be a 96s 2P configuration. Maximum 90kW for 1/4 mile run for hopefully under 15 seconds. We have built large domestic high voltage pylontech systems and LV systems with high current. We have a capable team however I would highly appreciate assistance from someone who has built a similar battery for a performance application.

1. Which brand is recommended?
2. Do we build a master slave or go with a single large BMS like the Orion?

Thank you.

Can i ask why choose an LTO instead of a more conventional chemistry like NCM or others?

You said EV performance application, and if it's LTO i'm guessing it's like a drag race rather than a track car?

But then again, if it's performance application, wouldn't 96S be too low for LTO? (actually looking at your voltage, 320V 96S means each cell is 3.3V? but isn't LTO 2.4V? do you have some secret battery ;))

Hi there. Ill look into NCM. Drag race for hopefully under 15 seconds. Sorry you are correct, 2.4V so would be like a 144s 2P. Have you ever had experience with this kind of pack before? Thank you for your feedback. much appreciated.

Orion would be another popular choice.

Orion worked well for us in the past
Hi there. I am under the impressing Drag race for hopefully under 15 seconds. Sorry you are correct, 2.4V so would be like a 144s 2P. Have you ever had experience with this kind of pack before? Thank you for your feedback. much appreciated.

LTO seems to be safe and able to handle a fast charge and discharge.

You hope to build the EV battery by yourself?
Do you considering let the battery company to do this action?
Usually LTO is not a good solution for EV as its size aand weight is too big. NMC and LFP is better.
LTO used for electric truck or electric bus while the temperature is wider.
If you need, you can contact me by whatsApp(Tony +8618894149209).
We would like to provide the solution for you.

Would second the use of Orion's BMS2. It is a great unit that has a lot of flexibility and capability. Depending on your budget, it may be a bit pricey, but it really does a lot reliably.
