Max Voltage for VL

[digmeup]

As the topic states, what is the max voltage in for the ssc32?
I`m considering using a voltage regulater that has a specified max output voltage of 9,27V.

9V is what most of us use for VL, since 9V batteries are easy to get. Check out the SSC-32 user manual to get all the exact details.

I believe 11V is the correct answer.

btw, many alkaline 9V rectangular batteries right out of the box are between 10 and 10.5V when fresh.

The absolute maximum rating from the datasheet is 26V, but I wouldn’t go anywhere near it. For safe use, I’d derate the usage down to half that, 13V or less. So 11-12V shouldn’t be a problem.

Many rechargeable “9V” aren’t actually 9V, but they are just 7x1.2V cells internally, so they are 8.4V nominal. They can possibly reach 9V at full charge. So these wimpy rechargeable “9V” might be more ideal to use, voltage-level-wise. The alkaline’s advantage is that they typically last 2 to 3 times longer due to their capacity compared to the rechargeable 9Vs out there. The highest capacity rechargeable nimh “9V” I’ve see are 280mAH… Anyone seen higher ones?

Where’d you see the 280mAH?

google “Accupower 9V NiMH 300” and they make some 300mah ones. Of course if you actually get 300mah out of them is anybodys guess.

This is just great guys! All the answers I were looking for!
Thanks! Guess that my 9.27 volts will not exactly kill the poor ssc.

Anyways thanks for the quick replies!
This is why I love Lynxmotion.

It’s from an ebay store called battery monster…

I bought two 9v 280mAH + Charger from this person, but BEWARE, he sent me 9V 200mAH + Charger. I believe it was an honest mistake, but these were so cheap, the shipping cost of returning and getting a new one and the trouble for it didn’t justify me raising an issue… Perhaps if I bought a HUGE quantity, I would’ve complained…

Just to put my mind at rest, probably no issues running off a 12v SLA battery?

Thanks

I just ordered a bunch of these, they are actually 9.6V 8)

Here’s the MAHA true 9.6V fresh off the charger. I almost want to crack one open to see how they did it!

Hmm, my guess would be they crammed in 8xAAAA cells. I think most of the alkaline 9V out there are comprised of AAAA cells… It’s one of the (somewhat) cheap ways to get AAAA cells if you’re very careful and know for certain that your 9V contains AAAA cells.

Personally, I’m a fan of the sub-c size since that size have been the standard for electric R/C cars for over 20 years (possibly longer)…

But wow, that maha cell seems pretty great. My Digimate only reaches 9.6V at full charge.

Ever measure it with a load? Say with the ssc-32 and botboard+atom/atompro hooked up with continuous serial commands spewing out of the botboard into the ssc-32?

I think you’re right, it must be 8x1.4V. I haven’t got that far in testing it yet, I’m just running my SSC-32 off the sub-C’s at the moment. In fact the only reason I have to mount that stinkin battery is for my MaxStream XBee dev board - anything less than 9V and it don’t wanna work at all.
