Hello,
I'm new to the forum, but I have been watching Will's YouTube (as well as David Poz) for a few months.
I just moved to FL and will install a Solar / Storage system in a few months (right now I'm renovating a home that my wife and I just bought).
We are in a golf cart community; approximately 95% of the people have the noisy / stinky gasoline powered carts (due to range anxiety)
My cart is 2007 Yamaha G29 (Drive) Pb-acid w/ DC motor.
I want to convert it to Li-Ion w/ AC motor asap.
Here's my idea / questions
TEEKON

I haven't researched BMS yet - I would need 24 S 72V, but don't know what amp rating I would need to supply to the controller (is it the controller Amp rating?)

Battery
- 72 V (24 series 3.2V cells). [https://offer.alibaba.com/cps/bednd...Lifepo4-3-2v-280Ah-Lithium_1600218570278.html ]. This would give me 10 KWh, and would require less current (heat / iRMS resistance) than 48V system.

OPTION A: (includes 440A controller)
4KW / 440A
OPTION B (includes 600A controller)
4KW / 600A
They have a 5 KW motor, but they don't have a package including it for Yamaha. I think there is a packaging issue (interference w/ rear suspension).
It may fit however if I modify the cart with a body or suspension lift. If I can make it fit, probably best to go with the 5KW vs 4 KW.

Any ideas for a BMS?
Do you see any issue with my plan? (72V) w/ 5 KW motor? (24 cells in series) [currently TEEKON is not available]
Any other ideas?
THANK YOU!
Paul
