Cool! What are you using for BMS? These things must be expensive and pretty big compared to the Leaf pack I am using.

75v and 250ah! That's a heck of a pack!

Were there Tesla BMS modules built into the pack already? Were you able to re-use them?

I'm running 18 series for what sounds similar to what you have there . About 75 volts hot off the charger if I go up to 4.15ish stays above 70v for quite a while once below 65 you can feel the loss of punch off the line .have a 16 volt boost pack though ,in case I come across a guru tuned rxv. My main pack is about 60ah and can charge from 58 volts to 74 with the top off in about 2 to 3 hours .
What's a charge time on a 200plus AH lithium pack?

Do you have a temperature monitoring device on the pack? I think Testla's are liquid cooled in the cars.....but I dunno if that's necessary in a golf cart.

What's a charge time on a 200plus AH lithium pack?
Managing the voltage and charge times must be quite a skill. Speaking of cool stuff, I've been toying with the idea of getting a Tesla lately, and I recently came across the Tesla Model 3 steering wheel. It's got this sleek and futuristic design that caught my eye. What are your thoughts on it?
Now, when it comes to a 200plus AH lithium pack, I imagine the charge time could be quite substantial. It depends on the charger's capacity and how depleted the pack is, but it's all about finding the right balance between waiting for a full charge and getting back on the road. It's fascinating how technology keeps evolving in both the EV world and the DIY electric vehicle scene. Have you made any other interesting modifications or improvements to your setup?"
