Where'd you get the "understanding" that a 10ah battery would give you 6hrs runtime with a Livescope setup ??
I got a 50ah Lithium and only got 6hrs runtime, but I think it was only 75-80% charged when I used it. I got a 50ah because I've read that a Garmin 93sv & LS can pull close to 5a/hr ... and I don't usually fish more than 10hrs straight on any trip. I believe I should get a good 8hrs continuous running with the battery fully charged. Now .... I've only used it one time, and like I said I don't think it was fully charged when I did use it .... and I haven't had the opportunity to use it a second time, when I know it's fully charged, to see what length of time it will last before shutting off.
The battery is a ECO-Worthy 50ah and I got it and the charger for around $250 ... and I just looked & could get the same two items for $200 right now. (shipping is free in USA) And NO ... I'm not promoting the battery or company ... I just bought it to try it out and to save on weight, since I have to carry batteries to & from my boat & carry them up/down stairs, due to living in an apt complex.
