Pros

Anderson Powerpole output plugs straight into ham radio and field gear without adapters
At 5.4 lb it fits in a pack or go-bag
Unusually long 20-year replacement warranty

Cons

Soft PVC pack with no case or water protection, so it needs a box for boats or kayaks
No low-temperature protection: charging below freezing voids the warranty
Much higher cost per watt-hour than hard-case 20Ah batteries
