scottiej Posted April 6, 2009 Report Share Posted April 6, 2009 Not too heavy. What are these 25 lbs ea.? Hmm, How much do 200 lbs actuators cost? lol I like the way you think. Yeah, just under 25lbs. No idea on the accuators... I'm sure JD will know XS POWER Batteries, Chargers & Accessories 888-4XS-POWER Link to comment Share on other sites More sharing options...
loopkiller Posted April 6, 2009 Report Share Posted April 6, 2009 I am getting about 12K out of that amp and those batteries are great for that. But I will be adding power, probably about 24K. These batteries are great cause of the quick power transfer and the fact that I can mount them anywhere. I can stuff them under seats if I have to. You must be running a 16v charge to them then? I know those amps are only rated up to 10kw @ 14.4v. Since the D925 is a 12V battery, you must have one hell of a 16V alt powering that amp to make 12kw. Not sure how else you would get 12kw out of a 12V battery bank. Link to comment Share on other sites More sharing options...

On 16v systems charging at 17.9v, people have gotten 18K out of them.

ISO Posted April 6, 2009 Report Share Posted April 6, 2009 (edited) Glad you like it man. I'll tell you what I'm shocked at how well that battery preforms. I use it with an 80 amp power supply and have a Stinger volt meter on it to make sure it doesn't start haveing voltage drops. (satefty issue to know when I'm over doing things and to turn everything down) So far it has been a great battery and I'm very happy that I didn't pass up on getting it. LOL I thought I was going to have an issue fitting my D2400 in my truck without modifacations, so I called the company I bought both batteries from and they told me that the S925 (D925) would be strong enough to use as a starter battery for awhile untill I could work things out for the D2400 to fit under my hood and all I can say is that I was blown away. (I got things worked out with the D2400) I really didn't think the S925 was going to be powerful enough to start a full size 1988 Chevy K3500 V8 5.7 Litter 1 ton pickup truck engine multiple times without killing the S925 quickly. Its a great battery PowerMaster and thanks to all the dealers. The D2400: Edited April 6, 2009 by ISO Isobaric - Refers to the practice of coupling two drivers together to make them act as one. "Giving up doesn't always mean you are weak; sometimes it means that you are strong enough to let go." Insanity: doing the same thing over and over again and expecting different results.

HHR Ed Posted April 6, 2009 Author Report Share Posted April 6, 2009 And just how are you measuring the output to know that you are getting 12kW out of it? I measure the loaded AC Voltage output at full burp at my frequency of 42hz. (imp rise can change at different frequencies) At the same time I use a shunt connected to a true RMS bench top multi meter set to AC current. I take my 2 numbers and multiply as P= I x E, or wattage= Current x Voltage. Then I also multiply by .707 for the root mean.

You might be right, but from what I understood is that you should already have an RMS value before multiplying it. I thought you only did that with peak values?

You might be right, but from what I understood is that you should already have an RMS value before multiplying it. I thought you only did that with peak values? The meter I used was a true RMS but not with the shunt transformer. This method was approved by the CFO of the company I was working for, he is the head electronic engineer for the company. Usually you dont need to multiply by .707 but its because we were using a seperate shunt to handle the high current.
