Great video Tony, thank you - found it and the CK61 ones very useful. You mentioned in passing using the pack at home to discharge it more fully before recharging for band practice. For what it’s worth it’s generally not necessary to regularly discharge modern LiPo batteries down, they can be kept at or near full and be perfectly fine. That said if the supplied manual says otherwise, go with that of course :) Thanks again!
Another advantage of running on batts: It can help reduce audio hum when using external amplification by eliminating the ground loop formed by the power supply leads and the audio lead.
Tony, I recently bought one of these initially for use with an Alesis Recital Pro, and then sold that and got a CK88. I want to pass on a 'cautionary note' to you and your readers on this Battery Pack. It is noted as 12V, but on close view of BOTH the label on the pack and in the instruction sheet, the output is not well regulated, and the voltage actually ranges between 9V and 12.6V. Both of the keyboards mentioned here can use batteries, the CK88 (8 AA's nominally 12V) Alesis (6 D cells nominally 9V). I did some voltage measurements over time comparing to the 5 Led 'meter' on the pack. Just leaving the power pack on continuously to where only 3 Led lights showed, and an hour into that, the output voltage had dropped to 10.54V. When only the 2 lights showed, the voltage was down to 10.4. At some point around this lower voltage, a well designed keyboard voltage regulator circuit 'should' shut down the board. However, as a cautionary note, I do not plan to run the board with less than 3 lights showing in order to avoid a risk
You can be confident the Yamaha has got plenty of protection against out-of-range PSU voltages - the circuitry will likely be protected both by hardware and software - particularly since it is designed to run on 8xAlkaline batts which will droop all the way down to
I bought the same model to fit under a pedaltrain nano board and power 3 pedals that draw a total of 1280ma at 12v. I feed the Talentcell into a CIOKS DC4 and the CIOKS feeds my pedals. The CIOKS can accept 9-24v on its DC input. I get 3 hours with this setup which seems to align with your 5-6 hours. The Yamaha CK88 states "11 watts" and at 12v would be 916ma. I know there is some power loss on my side as the CIOKS probably converts the voltage. The provided 1a charger cannot keep up with the 1.28a draw of my pedals. Even when I power off the largest pedal (900ma) and reduce the draw to 380ma....the charger still cannot keep up. I tried a 3rd party 12v 1.5a charger and that one cannot keep up with 380ma draw either. I don't get it. I also have the same experience with the lights not being accurate. I am deciding to keep the Talentcell or not. I am going to try a 3amp 12v charger as the manual states it can accept 3amp on the input and see if that keeps up with my pedals.
That sounds cool - I've switched to a 2 keyboard rig so trying to decide between a 2nd talentcell (with USB as well) or just go back to plugging things in lol. Thanks for checking out the channel, feel free to subscribe
Excellent! I’ve been using an amazon 8 AA battery pack to power my Yamaha MOFX. It works well but I’d have to bring more batteries for anything over a couple hours. This is much better. I’ve already got a battery power Bose S1 as my keyboard amp so it looks like I’ll be set for outdoor gigs next summer.
Cool! Have you ever used your Bose S1 as a monitor (connecting the output to a PA)? The sound guy told me the signal was so hot out of the Bose that he had to have me turn it down a bunch to have any control on the PA mixer (as a result it was turned so low I couldn't hear it anyways).
@@PianoTone Playing solo: The S1 has a 1/4” TRS balanced line output. I use a 1/4” TRS male to XLR male adaptor to go to the PA. An xlr to xlr transformer comes in handy if there’s ground hum. It works perfectly when it’s just myself on a solo gig. 1/4” mono from the S1 output into a direct box would probably work too but it wouldn’t be as clean. Your sound guy probably forgot to pad the mixer input or was reluctant to turn down the mixer input gain for your channel. Most “sound guys” never crack a manual. Playing in a band: I always DI the keys. I often use the S1 as a powered monitor with my personal keyboard/vocal/band mix coming from the mixer to the S1. If a separate monitor mix from the house mixer isn’t available, I DI the keys AND put a splitter on my mic. Sound guy gets separate vocal and keys and I can adjust my vocals and keys volume on the S1 without messing up the house mix. Note: the S1 has rather low microphone gain. I have a boss VE5 harmony/vocal effect unit that bumps up my mic gain giving a lot more vocal volume from the S1. The speaker stand pays off big time when you need to project over a crowd.
If you turn off the CK88 internal speakers and use external powered monitors - it will likely run all day on that battery pack since the audio amplifier is the biggest power draw.
Funny you should ask I'm actually agonizing about a mixer right now. I'm close to switching to a 2 keyboard setup for gigs so I need a small mixer for my 2 boards before they go to the amps/PA. I own a Yamaha MG06X which is a fantastic mixer, and it even has balanced XLR outs so it could serve as both a mixer and DI box - but it needs power. I have a cheap Moukey 8 channel line mixer (I reviewed that actually); they're crazy inexpensive and can be powered by USB but I've heard complaints about noise if those are powered by a USB hub vs. plugged into the wall. I also have a Roland GO:Mixer Pro which is awesome (but only one keyboard channel so that doesn't help me) so I'm deciding between just bringing the Yamaha and living with DC power (which saves me buying anything else and also saves me buying a DI box) or looking for a USB powered option and getting the beefier Talentcell. Most places my band is going to be playing are pubs/bars/halls so power's not an issue, but have to admit I love being fully battery operated!

Oh ok thanks for sharing that! There wasn’t anything in the manual so that’s great to know

Update. I received a 12v 3a charger and it is able to fully charge the battery while running all of my pedals at the same time. @@PianoTone
@@jayfoghino5392 Sounds nice, which model have you ended up choosing ? I am also interested for a DC4-powered pedalboard ;)
Good vid Tony. Very informative. Thanks and thumbs up.
Thanks!

Yeah I ended up never having the speakers on anyways and got tons of time (you can't hear them when I'm playing with a band)
Hi Tony. You referred to a USB-powered mixer? Which one do you use?
