Default Re: Ordered a 48V Plum Quick Speed Motor

Just remember mine was a converted 36V resistror type cart kicked up to 48V and then the PQ motor installed...overall I have gone from 13 mph to 19-20 and PQ is redoing my original motor as we speak, and I will post those results also when I get it...but...so far so good and I am running the stock 18 inch tires.

Scubby, The #s I am gonna give here come straight from the Trojan Battery site...for a 48 volt pack :
100% = 50.93 volts
90% = 50.47v
80% = 49.99v
70% = 49.49v
60% = 48.96v
50% = 48.41 volts

Remember the battery pack will have a high reading immediately after charging. This reading will settle after 30 minutes or so to a true reading....and 50% discharge is as low as the pack should be drawn down before recharging....
If you suspect your pack is not well check each cell with a simple hydrometer

Thanks Scotty

I was trying to show toogood4ubalius79 that it's OK to have the charger stay on the 2 AMP for a while. My batteries are brand new T-1275's and after the surface charge wears off they stay at 51.1 to 51.4 until I use the cart. Since they are new I try and charge them even when they are only at the 50 volt level which I get by going around the block a few times.

And the goofballs? what is that?

This link is from Trojan's Battery Testing Page listed below:http://www.trojanbattery.com/Battery...e/Testing.aspx

"If battery registers below the Table 1 values, the following conditions may exist:

1. The battery was left in a state of discharge too long.

2. The battery has a bad cell.

Batteries in these conditions should be taken to a specialist for further evaluation or retired from service."

Trojans Testing Page goes into alot of helpful detail about exactly how to test for battery condition.

Default Re: Ordered a 48V Plum Quick Speed Motor

OK finally had time to install and test my new Plum Quick motor this Past
weekend.
Just so you are aware my OLD motor was also a PQ standard wound motor,
It came with the cart when I baught it and is reported to be 3-4 Years Old.

SPECS.
1997 48 Volt DS
Battery Pack Voltage 50.8 Volt
Upgraded #4 gauage cables - just upgraded by me
Stock 225 Amp controller
6" lift, rear seat,
22" tires on Alum. Wheels, 15 lbs. pressure

OLD PQ = Up hill speed 8.5 mph
NEW PQ = Up hill speed 9.0 mph
OLD PQ = Flat land speed 14.5 mph
NEW PQ = Flat land speed 16.0 mph
OLD PQ = Down Hill speed 25.0 mph
NEW PQ = Down Hill speed 30.0 mph

Conclusion.
PQ may have made improvements in the past 3-4 year on winding process
or my old motor was degraded because of age.
Definatly more torque , dont have equipment or know how to measure this.
The thing which seems out of bounds to me is Why is the Down Hill speed
20% faster with the new motor , when the up hill and flat speeds only
6% and 10% respectively.

Open for thoughts , openions , discussions

Does PQ post any information in regards to what specs their motors perform at given certain controllers and so forth.

gmorrison,

what kind of hill are you talking about (grade slope or what kind of grade change)? Unless it is a really steep hill I would think you should be possibly be getting a little more than you are. I also think that is funny you get a such a larger percentage downhill, you would think that the flat land would be higher as well.

I upgraded my speed controller this past weekend from a stock 225 to a 480 (and #4 wires) and felt a significant increase in torque and a little speed.

Not to my knowledge,
I talked to the owner last week and according to him , the website was
developed by a friend 3.5 years ago and has never been updates.
Also according to him he has over 350 Motor/controller combos.
So call or email him see what his is willing to commit to, it would be
GREAT to have ALL this in writing !!!
