Has anyone had any luck sourcing a replacement battery for the iBasso D2 Viper?
The specs I found cite an "8.4v 470mAh Li-polymer battery".
Upon teardown of the Viper, what I found were two batteries, wired in series, that both pretty clearly say 3.7v each on them. Other identifiers are "ATL", what appears to be a model number (651748), and a 12-digit serial number starting 430425xxxxxx. They measure approximately 49 x 15 x 8 mm (8mm of the 49mm is for the terminals, the batteries appear to be about 41x15x8mm).
Any idea on where to find these? I've goggled a bunch of "iBasso Viper Battery" variants, as well as "ATL 3.7v" and "3.7v lithium polymer 50 x 15 mm" variants. I also couldn't find any relevant threads here on head-fi. Would love any pointers you all may have.
Also, seems to me that this is more like 7.4v, vs the 8.4v that they stated early on. I should be sourcing matching 3.7v batteries, no? Have my math or electrical engineering skillz failed me?
Thanks all!
