Charging Extreme DC

GarageBuilt

I use Odyssey batteries & charge them with a Delta Q. Things change. And now I will be useing a welding machine. First of all the batteries will take a very fast charge. And 2nd of all this is what they came up with for me to charge my batteries & push them to 13.8 volts in just min.

The total pack will charge up to 132. volts. So I will need a welding machine that can be set on 132 volts. The batteries can handle a 200 amp charge max. So amps on the welding machine would be set 200 max.

I would charge them as a single pack. And once the pack reached 132 volts.That would be it,

What do you Boys think, Can charging my Odyssey batteries be that EZ.

I dunno man.....I don't like to quick charge ANY battery much less than with a welding machine. I am a welder by trade and have done that to get things going if ya know what I mean. I usually replace the battery when I'm able to get where I need to be.

With that being said.....it's not the VOLTS that bothers me, its the AMPS. The amps is gonna be what kills the battery. Can you drop the amps and keep the volts where it needs to be? It might work better as far as lifespan for the pack. I'm not to familiar with the batteries though, they mght handle the extreme charge rate.

I looked at a Lincoln Welder 225 volts & fixed amps at 50. $265.00. What would I spend for one that would have at least 100 amp draw

roady69, I agree with you that this is not the best way to charge up a battery pack,
But this is a performance thing. I have cut my battery pack down under 30 amp hour. And that gives me around 1 or 2 minutes of run time. And that is plenty. But now I need to recharge to max voltage ASAP.

I saw this at BU does your battery guy stand behind this. The amps and volts are in the parameters but it seems extreme. Electric cars would be popular if this fast recharge was practical.

Odyssey is behind this type of chargering 100%. The welding machine, the volts & amps all came from them. Now its all about finding the right machine.

I will post pic's, display all the #'s & answer all the question, Right here.

Well I am pretty sure welders are AC, and that will not fly cahrging a battery.

The other problem is the amount of power you are talking about, Your residential service cannot supply that much power. It is pure ohm's law P=IE I=200
E = 132 volts
P = 26,400 watts

There is no circuit in your house that can supply that amount of power. Typical residential service is 100, 150, and 200 amp single phase

Just make sure you get a DC welder. Most cracker box 220 home units are AC.

They have me looking for a welder with a amp range of 100 to real low, with 110 volt plug.

I found a off brand at H/F today. It was 110 volt, The amp range is 75 down to 5 amps. The 5 amps is what I need to finish off & bring the battery pack to max voltage. 150.00 bucks

Why, do you say DC, & how low will the amps go.

WHY do I say DC? Because thats how you charge a battery. Thats the ONLY way to charge a battery. You are gonna have real problems finding a charger/welder that will run off 110 Volt AC and put out 100 amps DC @ 100% duty cycle....aint gonna happen. If you do the voltage it going to be REAL low on it and not work to do anything other than charge a low voltage battery. Thats with a transformer based welder, an inverter based welder with those specs is gonna be even harder to find. If you do find an INVERTER based welder with those specs the duty cycle will be too low and not charge at the rate you are wanting to. Your gonna have to have something with a 100% duty cycle to charge.

You need at LEAST a 220 volt AC input/DC output machine or a gas driven welder thats capable of 100 amps at 132 volts with 100% duty cycle at that output. Nothing else will work like you want it to. (They don't make them.) If they are trying to tell you otherwise have them point you to a machine that will do it.


That one you are looking at....those readings are probly "pulsed".....meaning it pulses. Not continuous output of 75AMPS at 132volts DC that you need. What is the voltage at 75 amps?
