I'm building an emergency solar generator for use with some low-power HAM radio equipment and this is wonderful for this. Being 10Amps, it'll be able to run my 5W transceiver for several days. The battery itself is quite light but feels well-made. Being LiFePO4 instead of the older Li-Ion battery chemistry, it's not quite as likely to burn down your house...but still keep a close eye on it when charging. A standard acid-gel battery charger won't work with this. You need a charger especially designed for lithium batteries, though most of those will have a setting for whichever battery type you have.
Overall, I'm very pleased with this battery.
