Hi guys,
I live in Montreal, Canada and cannot find a battery for my Roland accordion fr7x. Any thoughts?
Thanks

i just checked and indeed it appears neither Roland US nor Roland Canada
are carrying battery packs for the FR5,7, or 7x
BTY-FR
Amazon shows 5 in stock at a ridiculous price
there are articles here about making your own if you search

Here's one such post:
Battery pack for FR-7/7x/8x
Related thread: FBC-7 Eliminator This post was initially intended to be in this thread because Id like to clarify some points raised in the thread. But then I thought it was deserved its own thread. ... the 24 volt battery pack for the Roland models FR-5, 7, 7x & 8x ARE NOT made from the...

Before you start, a cautionary tale.
I once owned a battery operated screwdriver/drill.
The battery of this drill was worn out by age.
So, when I chanced across a battery rebuilding business, I thought I'll have them rebuilt the drill's old rechargeable battery.
( These guys had been making/ rebuilding batteries for 50 years)
All went well, until I actually got to using it, when a cloud of acrid blue smoke arose from the armature: goodbye drill, goodbye battery, goodbye rebuilding batteries idea
!
Nowadays, I'd just go for a new drill (or a used mains electric powered one.)

I live in the Montreal area too. You can order them at any Roland authorized dealer. I ordered mine from Long & McQuade in Longueuil. There is also the DIY option available too if you are handy.

Thanks so much for the info. What is the DIY option?

hehehe
you pick up a little battery welder
and some nickel strips and then a batch of NiMh batteries
then you need to buy a baggie of Thermistors, use 1 for each pack you make,
and a Molex connector
you get two to use like that and the wires are already there.. just cut the lengths in half
then some heat shrink to cover it up
now this size and quality battery works fine, charges nicely in the Roland system,
and gives good run time.. it is of course less than half as powerful
as the factory battery, but those industrial size cells are rather expensive for 20, and
harder to put together, while the AA size pack can be easily built in the
W configuration just like the original, but smaller, for under $50 bucks,
and you can make a bunch of them without going broke
if you need the longest run time for serious Gigging, AA battery packs
aren't enough, but if you are only doing 1 or 2 hour events, or just
want wireless freedom when you practice, they are great

Thank you so much. It was so kind of you to explain it in such detail!

Or you could use 7 larger batteries and go from 1 hour to 12 hours continuous of playing… lol

20 NiMh batteries at 1.2 volts each gives a nice 24 Volt output
at a pretty steady current until near depletion
unfortunately, more powerful NiMh SubC / C are too chubby for the compartment..
the original batteries HR-4/3FAU sanyo, are the optimal choice
but still cost around 10 bucks apiece
if you are thinking of trying Lithium
7 batteries x 3.7 volts = 25.9 volts while their fully charged
initial output voltage could start as high as 28 volts
and you could not charge them with the Roland system as designed,
and you need a voltage regulator control circuit on top of them to
regulate their output to 24 for the Roland
it is possible, has anyone done it successfully yet ?

Whilst I think all the suggestions are well intended .you have paid good money for the
Roland accordions......and you want to cut corners with cheap home made batteries.?
if there is still warranty on the instruments..I'm sure the warranty would not be valid in the event of problems..... Just my thoughts.....

i don't think there would be any FR-5, 7, or 7x still under warranty in the USA at all..
the initial period here was only 1 year
Roland Canada and Roland UK offered better warranties
there is nothing cheap about a home-made battery if it is built correctly and
carefully using good components.. this isn't Reed tuning or Rocket science..
the people making batteries for Roland are just like us, use small spot welders
and heat gun the heat shrink tubing with hands just like yours
no big deal, really
those specific TEnergy AA cells i pointed to are very nice quality and easy
to work with and last a long time.. i know the AA packs work well
and charge easily with the Roland pedalpowerboard because i
have been using them in the Studio to test them for a year now
i am getting too old to pull 4 hour gigs, so what do i need
the heavy original battery packs for anyways ?
i also made my own half height battery holder backplate with a
finger to push the hidden switch in so i can change them easily
and quickly
i believe in customizing things for my convenience, today, rather than
keeping things in pristine original condition for someone to
enjoy when i am ded

All very good points. Thanks for your as always very knowledgeable reply it's most appreciated.... Keep music alive Ventura...that's an order !!!!!!
Two people that I know of, yes (7 batteries at 3.7 each is 25.9 and seems to be within the safety margin/capabilities of my 8X for playing and charging, cannot speak for anyone else).
Dov Raines... and myself. I've not gone past 12 hours of playing time, but its still going strong the 2 times I went to 12 hours. I did not do it his way (set the accordion playing demo songs for 18 hours... LOL), thats would drive me crazy. I am on my 2nd set, first one was done 2 years ago and 2 months ago I went higher MAH (5500 mah)... it sure seems to be working.
Is it cheaper? Well, not sure in the USA, but in Canada the price of the factory battery pack (which I did purchase), was $421. The DIY was under $150... so in that sense, it is less for me.
Would I suggest someone else do it? Absolutely not. If you are not sure of what you are doing, it is simply smarter to pay for a new one from Roland and enjoy.

Lithium tech is really doing wonders for us.. making many things possible
i did pick up a small but amperage rated to handle the current draw of a
loud Roland 24 volt regulator that would fit on a pack inside the compartment,
but it is still in my "project" pile..
because of the dearth of replacement parts for V Accordions, i do not want to risk
over 24 volts personally
