That battery upgrade is a giant leap!mellymelsr said:

Good Job Melvin!
If some day I buy, I would go for the black version.

Yeah man, the quality time spent with it at breakfast that one morning sorta planted a bug in my head. The fact that it has such nice acoustics, actual metal for the speaker/main trims, and the high-quality components used for the controls, the wide variety of inputs (memory card, XJR, etc.) and kick-ass radio reception, and now the battery life of over a half-day... yeah I'm soldmellymelsr said:

Congrats Eric! The red one is sweet, I wanted a white one but I guess they never made one 
Battery upgrade??? I'm curious to hear more about this. Did you add another battery or find a good replacement?mellymelsr said:
I took out the stock battery which was a very cheap brand called Power Kingdom...lol. It was rated at 2.6 amp hours. Cranking it at the gym gave me less than 4 hours at 60% volume. That simply would not do. I measured how much available space I had. Then I researched what size and amp hour batteries were available. I wanted to make sure I didn't add too much weight. I settled on a 5 amp hour battery because it fit in the available space and only added 2 pounds. I preceded to do real world testing. I left it in my garage thumping at 70% volume with max bass to test it's limits. 14 hours later it was still going with power left. The replacement battery is a Duracell 5 ah and the difference was well worth the $35 cost. Also the original battery was only good for 50-75 recharges. The Duracell is good for 400+. So replacing it was a no brainer.trippy1313 said:
Oh yeah that's a definite must for only 4 hours at barely over half volume??? That's ridiculous.
2 pounds more is nothing for that kind of improvement. What's amazing is your new 5ah is lasting more and 3x they're supposed 2.6ah. I think they grossly overrated that label.
How much bigger in size volume is the Duracell?

Yep, a 2.6 amp hour cell is a little small for longer cranking sessions. The 5aH cells aren't that much bigger and should offer plenty of runtime. Considering SLA cells don't like overly deep discharges, having a bigger battery will offer better run times and longevity due to shallower discharges.Reli said:
I run 7.2aH SLA cells in my DIY builds - overkill really but for long weekends away from AC cranking the tunes and charging cellphones, this size cell has proven to be a wise choice.
It's the same height but the Duracell is twice as thick.trippy1313 said:
60% volume on this box is very loud. The bass hits very hard as well. Indoor volume setting is around 30% for me. I could probably get 18-20 hours at that volume with the bass at 50%. I purposely did my testing with bass and volume much higher to better test the limits of the upgraded battery. I am very happy with the results.
Mel and I did a tag-team video, and I played around with it in Movie Maker.....first time user! Had fun splicing in some music and captions here & there. I challenged myself to reduce it to 10 minutes or less, and I did it!

Excellent Review Mevin and Hans! That was two Professionals in action! 
Good job!
Basically when one removes the 7 screws that hold the front Al top panel gives access to the internals parts of the box right?
Love to see what is inside.

So far I've only taken the speakers out. They don't have names on them.
Well let me first say thank you for going to the trouble of making this video. I always hesitate in comparing old school boxes with the new stuff as I don't want to upset the diehard fans of the 70s and 80s gear.
What your video does is break the bad news to the vintage box lovers in such a way as to still acknowledge where the old tech devices still hold their own - in styling, loudness and mids and highs.
Even via a YouTube video, it's immediately obvious how low the beats go on the DJ Boombox. So to discover how easily the box internals can be accessed gets me thinking about all the sorts of interesting upgrade and customisation options.
I'm loving the use of old school and super reliable SLA battery technology - cheap and easy to swap out a tired cell a few years down the track with minimum downtime and fuss.
Those drivers are the real deal - you can tell they're expecting to see some power! You need plenty of power to sustain high bass output and the DJ Boombox obviously has all the power it needs.
To have all of the above in a cabinet design that pays direct homage to the classic 70s/80s 1 piecers is the icing on the cake.
Thanks again for your efforts,
James......

Sorry, I listen to Boomboxes....why would I know that word
Someone has to do an "Alien Autopsy" on this DJ Tech DJ boombox for the new and exciting boombox that is "in the works".
