Replacement batteries for ADJ QA5 wifly pars
Dan Nicholson:
Hi all
UK DJ here. I have 3 ADJ QA5 wifly pars that seem to be dying a death, after a full charge they last about 10 minutes on the battery.
Has anybody had the same problem? I'm thinking I need full replacement battery packs, which aren't cheap. 140 euros EACH from the ADJ parts site. Or alternatively getting some from Alibaba, although I don't totally trust going down that route.
Would love to hear what others would suggest
The battery packs I need are 18650, 6600mah, 22.2v, 18 cell (6x3)
Thanks

Have not used that light, but like the manual says: "Please do not let the battery fully die, this severly shortens the life of the battery"
Even if the battery status indicates “b050” is displayed (the battery is at half life), running the battery dead could kill cells- no life. The wifly par should have a LVC (low voltage cutout) to protect the batteries, but evidently does not...
Likely individual cells have died, it is possible to replace them, though may require a tack welder and a lot of time matching cells..
Good luck!

At least they ask nicely! But yeah, I hate equipment that just can't be turned off and left in the truck after a long job... Unfortunately with the battery-powered lights they really need to be billed as a semi-disposable item. Between drained batteries and ever-changing wireless equipment they're not a long-life item. They're great money makers but likely won't last the 10+ years we can expect from more heritage flavors of equipment... For liability reasons alone I'd say repairing a battery is a nonstarter. Hopefully Dan charges enough to use these lights that replacing the batteries every dozen(?) jobs or so can still be profitable!

Thanks Jeff for your reply. To be honest these have done me really well. I've had about 12 of them for about 7 years now and done hundreds of events with them, they certainly last a lot longer than 12 jobs. I might have to bite the bullet and get some from Alibaba!

Thanks Art, yeah I do my best to not let them die. I think the main culprit is sometimes accidently leaving the wireless dmx switch on, there's no light to indicate its on.
I imagine the whole pack has been affected, and as I don't really know what I'm doing probably not worth trying to repair!
