Looking at the Nico NPL30 I'm sure it would start your motor, but the specs show it's only a 7.8 Ah battery. If weight is the prime consideration, it will do the job, but not the best $:Ah ratio.

But if looking for more Ah capacity, the TPE batteries look attractive. Their Group 26 is 30Ah, 8.8 lbs, and $228 Or the Group 47 is 11 lbs and probably 40 Ah. Nice is they have a warning disconnect if the battery drops below 30% that can be reactivated by pressing a button, and that they already have brass battery posts built in.
