Ray,I had similar worries. What I got back from WarpspeedCE was that using the battery was important. I can tell you, it hasn't been an inconvenience in my system at all. What I did was spend a little more on a battery that I worked with WarpspeedCE on selecting. This has a couple of advantages: First, it has never run down. I have measured it after a month of extended listening and it has always been nearly fully charged. I learned that more frequent recharging rather than deep cycling the SLA batteries is preferred, so every few weeks I recharge it while I am at work (I have certain "long" work days that last 14+ hours so that is when I charge the battery...disconnected from the WS). Second, I know I bought the right "type" (both in type of battery and in connector style). Third, WarpspeedCE made the power cord with color coding for the tabs so it is simple to make sure you have the polarity right. And since it is a quick disconnect on the back of the WS, I never removed the power cord tabs. Very simple and worry free. You can see in the photo that the battery has a manufacture's "red" positive marking and the power cord is color coded "red" for positive and "black" for negative. Here is a quote of my charging comments and batter type from earlier in the thread, if that is helpful:Best,John
Hi, This may seem like a stupid question, ... here goes. I am thinking about getting one of your couplers. If I happen to wire the battery or 500MA 12VDC backwards, I know the LEDs won't work. Will this damage anything else?Also, I think I asked this before, and received no answer to this. You say the voltage requirements for this coupler is between 12V and 24V. If I raise the voltage to say 18V assuming I am using the same like a 500MA wallwart, will there be any differences here?Ray Bronk
Ray,The 'Squid (control circuit) will not conduct if the polarity is reversed. I suggest you do not do this deliberately just to find out -as this voids the warranty, and so with plugging-in an AC supply which definitely will break it. With a voltmeter and an ohmmeter, no way you will still reverse it...otherwise for your safety and that of the equipment have someone technically capable do it. Labeling and double-checking your work before plugging-in will also prevent accidents. 6V thru 24V will work.Battery power is still the best source of DC power. SMPS or even linear PS will still have spikes, ripples, and noise artifacts that will couple to the LDRs. I recommend you acquire your SLA battery/charger before you receive your unit. If you don't mind using alkalines, which I do use...I can also build a 4x 9V battery harness on request.
Ok, I meant it more as a precaution for everyone who reads thru our posts. Usually one's questions are someone else's too.Anywhere between 6V to 24V is optimum dc voltage...will not affect performance. I've tried listening with 9V and 12V battery supplies but can't tell the difference. I've only bench tested with the other voltages like 6V, 18V and 24V.I've had my (8x 1.5V)x2 Duracell alkalines for 13 months now and the reading today is 11.11V. For the 4x 9V at 3 hours daily use on a V4, I expect it to last 6 months or more. I say forget about the wallwart...
Also by being at "The CZ", I won't have to think twice if my postings have promotional content? Please correct me if I got that wrong.Thanks!
I'm saddened to learn that the fine craftsman from Oregon who took on making the Warpspeed front/rear panels has passed away. For privacy reasons I won't state his name here as he is not a member. I'm proud that his work resides with my work and is being enjoyed both visually and aurally around the world.Rest in peace KMK...
