Will the odyssey PC680 be strong enough to start my IO390 well? 
My actual battery with 25Ah hardly kicks the prop over the first attempt. Rising the gear with the -32 Oilpump-gear sometimes 
throws the Alt-field fuse. 
The PC680 has only 17Ah, but seems to provide the needed power quicker than my actual battery.

Careful with LiIon technology.  I worked for several years on the electronics and software to control high capacity LIIon systems that required high peek currents.  You have to take real good care of them or they like to burn, well, explode and then burn.
