Looks neat, I'm assuming that RE0 is a DAC output that controls the current source, but not sure about DE0's connection to I-, if that's also a DAC pin can it handle the full output current?

See pic related. The only switching frequencies present are the PWM frequency and its harmonics, but the duty-cycle varies at a much slower speed. Low-pass filtering the PWM waveform results in the whole thing being smoothed out to look like a sine wave. Look at how class-D amplifiers work.

Do you mean LiFePO4 (lithium iron phosphate chemistry), or lipo (lithium polymer pouch)?
