wkola, most if not all will agree that if you run down the pack to the levels you indicate then you will be replacing those batteries much sooner which I suppose is good if you're in the battery business.

Your numbers are a bit off but besides that we just don't want anyone reading this to think it is OK to discharge batteries to that level. It is simply not "good practice."

For reference:
A 48v pack at 50% charge is 48.41v or 2.017v/cell
A 36v pack at 50% charge is 36.31v or 2.017v/cell

For maximum performance and service life this would be the very lowest state of charge before recharging. "Emergency" discharges on rare occasions can be tolerated but anything lower than this causes permanent and irreparable damage to the plates. It is just chemistry and cannot be denied.

Not flaming or trying to start an argument as I think generally all discussion is a good thing but some might read this thread and get the wrong idea on how to operate and maintain a battery utilizing best safe practice.

Just my $.02

Spend it wisely.

A hydrometer reading of 1.277 per cell or greater indicates a full charge...not 12.65 or whatever your talking about. Thats straight from trojan batteries site.



I agree 150% with pggroves.

My experience with Marine batteries coincides with your post. My question is where and how you measure this voltage. For full charge; I measure the pack voltage at B+ and B-, while the cart is static. Is that the same measurement you're quoting at 36.31?

Also, I would certainly appreciate any suggestions about a guage that will give me an accurate measurement (more accurate than the stock vertical indicator on my PDS cart). I don't usually run around with my VOM hooked up.

Should I stop, shut off every thing and then take the measurement?

Thanks

Some like the led gauges but to me they wait and wait and then move - in stages so that the first time it drops a light (or two) you need to charge. The analogue red & green style reads anytime you push the gas. Especially when you load the batteries such as full throttle uphill. My 48v cart will touch the red doing this only when ready to recharge or 48.5 volts. Until then it stays in the green no mater what I ask it to do. We have alot of hills...

The voltage reference is open circuit voltage and comes from Trojan.

As far as gauges, I like this one. Most won't like the price tho'. But it is the most informative at a glance.

Man, that trace meter is very nice.

Is the one in the picture the $300.00 one?

Your gauge looks like the one on the right, correct?



Charge it up real good the needle will be in the white to red. Once off the charger look at it again and see where it is. When you hit the gas pedal it will fall toward the left into the green. The longer you ride the farther toward the left it will drop. When you are sitting stil the needle should bounce back toward the white. When it starts staying in the green toward the left is when you need to charge it. If you hit the pedal and it goes to the red on the left it's time to charge it also. Hope this helps.
