Hello VA,
The BMS is what Nick is now providing with his packs from HAC.
SD Technology Pt. No. BML-14 v1.03. We now have 5 packs running around our club. Three are 7 modules, mine is 14 modules like yours only split 6-8 (06 Precedent), the last one is 10m/5c paralleled for 41.2V fully charged. It is on a bone stock 36V TXT. Still only goes 20mph but has great range with the double pack and less weight. It is quite peppy and rides so nice when you get the LA battery weight out of the cart.

Looking good.

205/40-12 tires convert to 18.5" tall so if my math is correct 12.44:1 stock gear ratio, 32 mph would be about 7250 rpm.

Does that sound right?

OOPS - Error on my tire size 215/40-12 need to change that. My cart is Precedent with the 12.3 ratio. Next week installing new 10.3 transaxle and Executioner motor. Isn't the 12.44 ratio EZGO. Earlier question: Charger is one of those Chinese models that Nick likes to use.

ScottyB,
Back to tires on TXT upgrade. They are 205/65-10 for the 20.5" tire and the 12.44 axle. That would be 525 axle rpm @ 32mph. Thus a motor rpm of right at 6500 if the calculator I use is correct.

Even 215/40-12 tires only work out to 18.77" tall. However, the numbers on the sidewall are very approximate and can be off by an inch or more in either direction.

So is the 20.5" tires mentioned in your first post the actual measured height of the tires on the EZGO 2006 PDS you put the lithium batteries in?

If so, the motor spins at 6527 RPM at 32 MPH.

The XCT logs motor RPM (they call it speed in the data log) as well as Field amps, so what is the field amps when you are running at about 6500 RPM in the log?

If it is dipping below 2A, you might want to start monitoring the motor temperature.

The weight reduction is nice. Mine was minus 250 lb with the 14 modules. It rides great with two people in it but it's like an empty pickup truck with just me in it. The springs are designed for the heavy battery load. I have my charger external - looks like a different unit from yours. I also got my stuff from Hybrid Auto but back in December.

Here is a pic of the charger I got from Nick when I installed mine Oct '15. This one is Chinese as well. I had fuse blowing problems early on with mine and also with the new one installed in this post. The solder actually melts and opens the circuit. Chiinese spare built in fuse did the same thing. I found those oddball size fuses 'made in America' and have had no problems since. Also a pic of one of the fuses. The wire part of the fuse is still in tact, solder melted.
