Yea, I know haha. I was picking up a car dolly yesterday and was not able to respond until I got all the messages at once. In the maintenance field in the military, we already knew people gotta give you a hard time, when their true goal is to make it easier lol.
Also, the batteries were already fully charged when I tried that last charge. So I will drive it around for a bit and try what was noted. I only saw the 16v for a couple seconds before it red lighted.
Everything you all have said so far is adding up pretty fast lol. I canāt give much back to this community other than being a test dummy! We are getting a lot of useful information in a short amount of time in my opinion. 1. Military A-holes like to unplug blue tiny wires to piss people off. 2. New algorithms can be chosen with the master switch (even if not preferred), instead of the tap method. 3. Teamwork does indeed make the dream work. And that my friends is a win for this entire community.
That 16v spike is actually often used ā¦
ā¦ to crack the sulfide oxidation that forms on the surface of the plates
I believe it is also used as a brute force attempt to equalize all the batteries. The high ones get overcharged and will come down when cooled, and the low batteries have a more of a chance to get up to full potential.
To get full potential from your pack, the individual batteries must all be in the same charge state. A balanced pack is a happy pack. There is nothing in this basic cart design that monitors the condition of your batteries beyond the pack as a whole. The charger doesnāt see it, and the motor controller doesnāt care. If one battery is lower than the rest, it goes undetected and usually drops down below the save operating voltage and can be damaged eventually bringing down your whole pack.
This is the advantage of installing something more modern. Lithium packs today have the ability to monitor voltages down at a cellular level (even better than checking the 6) 12v batteries manually) ā but who does that?
I have AGM batteries in my train and I installed an active battery balancer which shuffles current around to equalize the voltages across all the batteries. Works great.. keeps them within about 20-30mV after charging. Got it off Amazon.
Thank you both for getting me to this point! Got her on the course today! For some reason the parking brake decided to give out on meā¦ but thatās for another day to look at.. lol .Also, need to buy wheel spacers to make it easier to get on the dolly.. just barely go on those ramps.
Correct. Almost all lead acid cell series packs are brute force eqalized. This includes everthing, even thibgs like the 1000+ amp packs in forklifts.
The DQ is a but of an enigma in its programming / algorithms and its decision making. Iāve never been able to find or get my hands on charge curves or step points. Other chargers out there, not hard to find. Even other high frqequency chargers like Zivan. The cuves are posted by the manufacturer. DQ keeps everything secret.
The DQ is smart enough to get an idea when the plates in an FLA start to form sulferoxide coatings, since its non or poorly conductive. It can tell by the increased resistance and will adjust for it, in output frequency and voltage. How and when they wonāt say.
The catch is, as you said, the DQ cant tell if the cells in rhe center of the pack are sagging. Even the $6k forklift charger cant tell etherā¦
But somewhere in FLA algorithms, it has conditions or possibly a counter or it compares resilts. The programmer software includes features that while not accessable on all chargers or firmwares hint at flash ram.
The forklift chargers and ither industrial chargers have a button to initiate the equalize charge.
For the DQ and most small chargers, to manually initiate or maybe simulate is the better word, one just does back to back charge cycles.
They probaly watched The Hurt Locker one too many times. Its always the blue wire.
I have a suspicion that the DH was disconnected to prevent the GEM from exceeding posted speed limits on site / base.
Thats what i would do to keep it simple.
And hereās the funny part, since i was a squid, it was about 2 years in before i ever ate them. There really are some unilateral truths no matter which of the 5 logos you chose..
The parking brake acts on the rear drums, but since they lack self-adjusters, you have treat it differently. In the end they are just tiny āfoundation brakesā like a car may have in whole or part. If you get stuck, anyone who knows automotive drum brakes should be able to lend a hands on or advice. Dont rely on just the cable take up procedure in the manual. If you need new shoes, which cerainly a possibility on an eLXD with 14k miles, my first call would be to NEV Accessories in Arizona. Then the big dealer in Sarasotta Florida. I forget their name offhand.
Spacers are 4x4 inch bolt pattern. Dont let anyone bullstein you into 4x100 metric. The manual clearly states 4x4. 4" is 102mm so yeah, an over clearanced (or one with blown out donught holesā¦) 4x100 will fit but not quite right. NEVA may have these but they may be for their disc brake conversion kits for 00-04 which iirc, are 4x100 (or 4x100 on one side)..
They will pop up in searches thanks to SCO optimization, but I would avoid Ride-4-Fun aka R$F whenever possible, their parts are largely meh, its a one person operation who isnt very knowedgeable yet touts himself as an expert and is a bit of a jerk.
