Finally chose lithium over lead-acid for my portable jump pack

Was stuck between a $200 AGM unit and a $350 lithium one for my side gig. Picked the lithium last month, and it fired up a dead Cessna 172 battery in 30 seconds flat. Anyone else made the switch and seen a big weight difference in your kit?

Wait, doesn't the cold weather mess with lithium packs though? I used to think lead-acid was way more reliable for that reason lol. But a buddy of mine brought his lithium jump pack out when we were trying to start my buddy's dead truck in like 20 degree weather and it fired right up no problem. That totally changed my mind about them. Now I'm looking at swapping my old heavy lead-acid battery for a lithium one just for the weight savings, honestly. The portability factor is huge when you're lugging gear around.
