    I have been so happy with the BTR3 that I know BTR5 is going to be a sure buy. Specs sound great.

    I’m already going to order an upgrade balanced 2.5mm cable for my earphones just so that I will be able to plug it into the BTR5.

    Surprised still no reviews.

    Hi, I am using Fiio BTR3 with USB Audio Player Pro (UAPP) and I see that it uses the Android driver.

    I want to know if it is possible to use the HiRes driver with the Fiio BTR3, and if so, how can I select it.

    Thank you.

    Hi,
    my battery seems to be worse and worse everyday so I asked FiiO for replacement and they told to me that they can't send me new battery but if I send them my device they can replace the battery. I'm afraid that costs of sending this from UK to China and back will be more expensive than new device.
    I'm an electronics technician so I disassembled my device to check what's inside. Inside I found AEC471738, 300mAh battery. This number is a size of a cell so it's 38x17x4.7mm. The problem is there's no battery sized like this with that capacity. It seems that AEC which is manufacturer of FiiO batteries is only one company which can make 300mAh battery that size. The smallest battery I found with 300mAh capacity is 40x17x5mm and all smaller batteries are 250 or max 280mAh. So my question is the AES batteries are so good that they packed 300mAh in 250mAh sized battery or it's 250mAh battery with bad value printed on cell?

    If you do a browser search with the word "AEC471738" you will find a PDF file with a list of AEC branded batteries. The AEC471738 is included in the list, with a minimum listed capacity of 300 mAh.

    I found it too but isn't that weird that only AEC can make batteries like this?

    You can find similar batteries online by other manufacturers. It is possible that you can fit a 402030 (4.0 mm x 20 mm x 30 mm) battery in the BTR3, by getting rid of some of the outer plastic cover material. The 402030 comes in 200 mAh and 300 mAh capacities.

    If you search hard (ha ha), you will succeed at getting a suitable replacement battery.

    There is enough space to fit 40x17x5 and already found and ordered matching battery. Anyway it's still weird for me that there is no way to buy same battery as original and now I'm gonna have to cut out plastic clip from the inside to fit bigger battery at same capacity.

    Can you please upload some pics and instructions on how to open up the BTR3 and carry out the battery replacement.

    It would be very useful to the rest of the community. Cheers

    It's easy like replacing battery in Chinese toys. You just need to pry plastic cover with some flat but not too sharp tool and swipe it around. There is plastic clip on the top so don't pry from that side. It's glued so you gonna have to use some force to take it off but don't try too hard to avoid puncture the battery. After you take off plastic cover peel off battery gently and desolder wires. Next solder new battery and use some tape to stick it to motherboard. Place plastic cover and use some glue (B7000 preferable, avoid Super Glue) to stick it. My clip felt off many months ago, so my plastic cover looks different but it's just a piece of plastic.

    Hi to all,

    I have just bought the Samsung S4 (model T830) tablet with Bluetooth 5.0 but I cannot connect it with my btr3. Does this happen because of the lower version of btr's 3 bluetooth???

    Dear friend,

    Please check whether your BTR3 is in pairing mode first? After turning on the BTR3, you could hold the multifunctional for about 5s to force enter pairing mode. The blue and red light will flash alternately at that time. Can't your S4 search the BTR3 still?

    Best regards
