How many amps are they ???

Battery is approximately a 2.26Ah. Manufacturer rates the battery at 29Wh. Watt Hours = Amp Hours x Voltage. Lithium-ion Iron Phosphate batteries are typically (4) 3.2v cells (12.8v), so, 29Wh = 2.26Ah x 12.8v. This is my third LiFe powersports battery for three different motorcycles, I will never return to lead acid.

Can I use this to start my outboarx and will the outb outboard charge the battery?

Check the CCA (Cold Cranking Amps) of your outboard motor’s ops manual. Advice: Never mess around in a marine environment and you might want to simply get a new battery for your boat. If you’re looking for a jump-start you may want to get a jump-start pack.

Anyone ever tried one of these on a 12v converted N Ford Tractor?

Get a larger one then this size

Does it have enough amps to crank over my Yamaha 1600 cc Roadstar ?

I have not tried it I turned it into a backup power supply when the power is down I can charge my phone or plug in CB radio I know you need high cranking power I don't think you have any problems with this
