I need advice about the best choice of batteries for an asg 29e. lithium

ion would be outside manufacturer's remit and the insurer's plus too many

risks-the fuel tank is directly above the battery housings. I would like

something with at least 9 amp hours, whether gel cell or mh.

from another posting -

I did, however, get behind my panel last week and changed out my master
switch for one more substantial in current capability and have experienced a
major improvement in function of my equipment. The switch that was
installed when I bought the glider was adequate for the CAI302 and the
MicroAir 760 but, after installing a Trig transponder, a Dell Steak and a
Zaon MRX, all operated from the same bus, the current capacity of the master
switch was the limiting factor. After two flights with the new master
switch installed it would appear that the problem is solved.
