    48 hours seems short, I can get about 70-80 hours per charge. It should fully charge the battery around 2 hours and I keep it off when I recharge.

    You should be able to use the Mustang while plugged in for charging. I think I remember Ray writing about that. You'll get different arguments about Lithium Ion batteries, but my experience with them is that they lose a bit of their maximum charging capacity each time they drain completely. That is below 10%. I don't think the amp will run the batteries that low though.

    Enjoy the amp.

    Ray wrote to me so here is what he told me:

    It makes no difference if my amp is on or off while recharging. 2-3 hours should recharge battery completly. In manual i've found information about 56hrs of usage per one battery charge.

    From my usage of the P-51 , 70-80hrs per charge looks to be the norm. Using IEM do seems to extend the hours slightly more. I alternates between SR80i ( 32 ohms) headphone and UM2 and noticed that IEM last longer. BAse on my usage 3-4 days more before i need a charge.

    P51 can be used while charging. [​IMG]

    As usual all new AMp requires to charge longer than normal on its 1st charge and would reach its optimal discharge cycle after 3-4 full discharge.

    On 75% of the scale and mid gain, when i burned my amp with the help of Aurvana Live!, my mustang was on exactly 52,5 hrs so it's a good score i think. But is it possible to get from him another 20hrs when using it with Westone 3 or something like that? Do couple ohms of impedance make such a difference in battery life in mustang? Anyone?
