Default Help me find a battery for myu AC-51 motor

I purchased a complete AC-51 motor and I'm planning to run it at 144v for maximum power in the upper range, however I'm having a hard time trying to find a battery for it.

Option #1: Leaf battery:
Very difficult to find good battery pack source, I just have junk yards batteries.
I need a full battery of 48 modules and extra 12 batteries, I'll need to build a 20S3P out of (60 leaf modules) in order to get 150V and 27kWh. At the time I couldn't find any Leaf battery sellers with tested modules.

Option #2: Tesla batteries:
I was planning to get Tesla modules but in order to get 144v I'll need 6 modules of 25.9v each for a total of 155.4v nominal, it won't align very well with the AC-51 motor which ir 144v nominal

Option #3: Enerdel MP320-049 24 kWh Battery Pack
Ths option is perfect but it's very expensive U$ 13,299.00, this puts me out of my budget.

Are there other alternatives in order to make these options more accesible?

Option (4) - two Volt packs - about $2000 each
Seem to be more robust than Leaf packs due to better thermal management - and you can get more power out of them

I spoke with Neli at EV Battery Center, they recommended a 34kWh battery pack made for Merceds by Tesla.



I'm going to need 12 Mercedes/Tesla packs and I'll get the BMS from Orion

Maximum voltage depends on the controller more than the motor, you might even be better of with 7 modules to keep battery voltage higher with almost empty batteries.

I can help you with NEW Volt and FOCUS batteries, not from a junkie like the other guys. Provide a tel# and I will call you.
