Only a thick mat calcium neg plate telecom battery demands a definite ampere charge limit. The rest are "phugger in and hang on". I've seen 27 Odysseys accept 60+ amperes. My 31 Lifeline gobbles 109 amperes saturated acceptance @ 14.4
Is this thread about coverters or battery chargers and what to what musical chairs generators and charge devices...?
Anything but a power corrected charger for the small generator is a waste of time and money.
When thinking charge devices think new Ford pickups with a 270 amp alternator and the vehicle batteries. Does it kill the batteries? No.
A Meanwell RSP 320-15 set on 14.4 volts is the way to go with a little Yamaha. It is chugging away as hard as it can and what else could you ask for? You aren't going to find another more efficient way to use the 1000 watts, period.
