Need advice for field power.

[Firestem4]

Hi there!

It's been a while since I've flown but I'm trying to get some gear together so I can start again. I've been trying to decide which way I should go and wanted to get some input.
Should I?
1) buy an AC charger and a handful of batteries. Charge at home and bring the batteries to the field.

2) buy a big deep cycle battery, get a dc charger and only a few lipo batteries. (would need a charger/tender for that big battery which means higher cost.)

3) buy a jump starter that has DC and an inverter built in but less amp hours than the marine battery, and I'd have a few options for chargers, and get only a few lipos.

What would you guys do?I like the jump starter just because it has a few extra uses with a built in inverter and an auto charger for the battery which buying a marine battery is more expensive since I need a separate charger . Although a marine battery has significantly more Ah.

In the end . does anyone need power at the field for other stuff if they bring a truckload of ready charged batteries?

Thanks!
