12V battery jump box recomendations?

[LittleBill21]

I almost just made a jumper from scratch. I would have used a high CCA battery, then simply wired in 2 or 0-gauge jumper cables & stored it plugged into a smart charger. Weight wouldn't bother me, I'd have to have it in a substantial box with handle.
The battery was weak on my Deere 3038 so I went back to Wal-Mart getting an Everstart group 51R battery for $79. Only 1 year warranty but it started it fine.

a lipo models weighs less than a pound , will last longer, and take less room

it shouldn't, one bar should be 75%, i routinely run around there with mine, but its not a noco

Im not sure otherwise, but the thing about the NOCO is that at full charge it provides a "HARD" source to your system at a ~15 V level. This zaps your dead battery and the starter. It really spins the engine up for a few seconds. It will start if its gonna. -- At one bar down its more like jumping from a regular 12 battery .. and there also, only for a few seconds. The "Hot" 15V jump is a huge advantage, especially when the engine is cold.

is this some kind of mode? i have an idea of how these work, and those voltages don't make a ton of sense to me

More like a feature of the NOCO. The battery pack has a slightly higher rest voltage than a normal 12V automotive system, and can deliver very high current for a short time before dropping off to normal ~ 11V levels seen during cranking.

Do you suppose that is what the "boost" button on my GooLoo does?

I dont know. Typically you just get whatever voltage is present (characteristic of the type of cells and their current state of charge) and have no option to increase or decrease it with a button.

boost button typical is used when the voltage is so low on the battery the jump pack doesn't detect it. you will see it turn on and the relay click even if disconnected

I am also a fan of the Project Farm comparo on Utube. Very interesting the 2 types of boosters: battery-based and capacitor-based, and how they perform.

And the "winner" is???

The GBX155 Noco won by a mile. It’s also a $400 box. The Gooloo did good for a cheap price.
