I flew a 12 a/h LiFe PO4 this year and can't say enough about it performance. I haven't seen the voltage drop much below 12.9 V, even on a 4 hour flight with everything on, Radio, transponder, Power flarm, Model-20 & Garmin GPS's, SN-10, B-500. AND it weighs half its lead acid 12 a/h brother which would give up in less than 3 hours.

I been thinking about changing to the LiFe Po4 well but must admit I am somewhat apprehensive.
It sounds like the 12ah version should be better (space allowing) than the 9ah for obvious reasons and I am not sure about the charging procedures either.
The chargers these batteries come with are they sufficient enough?
Can one leave them on overnight, etc, do they overcharge or like the gel cell smart chargers; switch to trickle charge?
If I sound ignorant about this, it is because I am .
Any advise would be appreciated.
