CS9000 7200w 10.44v (but with extra click of volume that wouldn't gain with NSB but would dropped NSB to 9.65v)
Spl gain .5db exactly.
These test where done with a charge of 20 amp and up to 16.7v for a min, then charger off for burp.
But the biggest improvement.
If anyone knows an NSB90 at all you know that it does it's best number nuked a little. For example the NSB will put out more power when charged on a 20 amp up to 16.5v than if charged with just 2amp at 15v. In our test we saw a .4db difference when tested this way and a .4 difference in voltage drop on the NSB. But with the CS9000 it didn't matter. If you charged it on 20 amp or 2 amp it did the same number with same voltage drop. This is very important because this battery doesn't depend on that big surface charge to do it's power. So the total gain is as much as .9 between batteries depending on way the nsb was charged. Over all very nice investment.
Next test CS9000 vs. Batcap 8400/DD battery
I expect with in .2db
And this test will be done only with Batcap charger. So, no charge over 14.2v

Intresting Tests..... Thanks for sharing the results with us. I would love to see the DD vs CS Test.. Keep us up dated. Go Team Cactus...

Thanks for sharing and Most people are fully aware of this. We don't do this for an extended period of time. We have been doing this to our nsb for a long time and they still as strong as they where when they where new.

Update: Came back next day and burped it with no charge and backed up the number from day before. Only loss about .2v on voltgage drop. After a little charge gained another .1db. So still very satisfied with results.

Hmmmm... SO you say you are still gaining from the bat??? Every day you test you see a gain just off the bat. Just remember what I told you about the voltage drop...

How much ampere did u get out of the batt?
My guess, about 600A @ 10.04v... he probably doesnt have a clamp that reads that high or I suppose he would have posted it too...
yes, maybe. But then u can read the amperage on each amp and multiply it by 2, 4 ...
it would be still nice to see how much ampere you got out
lol.... how cares what a draw... it is louder that is what counts in DB Drag. The score shows on the meter is what counts.

Ive already let mine sit for over two weeks and then just go to the shop and burp it out of the blue and it'll post the same if not higher socre then the time before.

But .1 of a db can be gained in a lot of different places, might not be from the battery. Could be from just the subs being cooled down? But also could gain from cycling a new battery and getting a better charge through it, or even something stupid as something changing inside the vehicle that gained that .1?

when i did my 160.8 in street C my batts dropped to 9.8v and pulled 2300 ampere out off them (4 amps)
now i have 10.4v left , dunno what ampere's i get now , same amps , same impedance

interesting. I charged my nsb90s up to 16.5 today and saw no gain at all. How long should I keep it in the 16s? I had it fully charged on my powermaster charger at 14.75 then switched to my manual charger after for around 25 minutes.

I don't recommend this for a long period of time because it will over charge the battery over time. We do it for short burst to get the battery back up quickly after a burp. A lot of things come into play if you will see a gain this way or not. What kind of amps do you use? Our amps are very voltage dependent and react differently to other amps when it comes to higher voltage. What kind of draw do you have on the batteries? I see you are in street C. We also have a street C car with two NSB's and we do see a gain once we give them a little higher voltage charge. But again it may be our amps. And we only see this difference if we use full power and drop our battery into the low 11 to 10v range.
