V-mount battery question for Light

I have Luxli Timpani 1X1 RGBW light. I have some Maxoak BP-GL175 12,000mAh 14.8v 177Wh V-lock batteries that I use flawlessly in my Astra 6X lights with no issues. However, the same battery will rarely work on my Luxli. It will power up the rear display and allow all the controls to be selected but the light will not light at all, the brightness adjustment will not go above 0%. So I turn it on and off remove the battery, etc and every once in a while it will turn on and work fine.

So I tried it on AC power and it seems to work consistantly that way.
Then I tried my Dracast V-lock batteries which are 14.8v but only 90Wh and all of them seem to work every time.
The luxli timpani rated max power draw is 120w.
The astra 6x bicolor is 105w.

It's been over 30 days since I bought it so it says no longer able to return.
So, what about just using my 90Wh batteries with it? Does that just equate to shorter run time, like less than an hour?
Again, the Maxoak 177Wh batteries work every time in my Astras...
Thoughts?
 
In case anyone comes across this thread with the same question, Luxli got in touch with me and said this:

"The developers got back to me and this is what they said : I looked up the Maxoak battery on Amazon, and it seems that the max draw that the battery can handle is less than 10 amps. The Timpani requires 10 amp minimum draw when using a battery."
 
Generally, batt companies and lighting companies seem to be getting better at listing the continuous draw on their spec sheets, but it's still not where you'd want it to be. The continuous draw required for the light and continuous draw offered by the battery is what we need to know. There are situations where you can absolutely power up a light, but you are draining it at a rate that is also greatly diminishing the long term life of the battery. Again, this is where conservative continuous draw ratings are useful.

It's also important (and a bummer) to note that that the batteries that can provide high continuous draw for many of the more recent higher wattage LED fixtures, are also pretty damn expensive. Aputure recommends continuous 15 amp draw batteries for their 300dmk2. Take a look for those batteries on the market and you'll see that a pair will cost you the same as the fixture, more or less. I can run my 300dmk2 on some cheaper batteries, but the operation time is not very long on the highest settings regardless of the w/h rating, and you are punishing the long term life of the battery. You'll also see that a battery with a runtime indicator display will say there is 40 or 50% runtime left, and then the light will turn off, because the battery cannot deliver the draw required.

I guess this is why things are moving toward 26v batteries, but then those are also expensive.

There seems to be no cheap solution for battery powering the bigger and more powerful fixtures for now.

BTW, the Astra 6x requires 8.5-3.42 amps based on the chart found here: https://www.litepanels.com/media/6554/run-time-chart.pdf
That's a 105 watt panel.
