Think they will work? (Li batteries).
One horsepower is 768watts. Divided by 2 (for 0.5 hp) = 368w.
368 watts/24volts = 15 amperes of current. That's assuming your motor is ALWAYS running at 1/2 HP, but I doubt it is.
About those batteries in your link: They are 10ah. They show a discharge rate of 20A max continuous, 60A max 2-second pulse. ... For longest lifetime recommended discharge rate 1-5Amps
My opinion ( and that's all it is):
Let's say your bike draws 8 amps at 24v. (running at 1/4hp) That's 8 amps from EACH 12v battery, since they're in series. 8 amps for 1 hour = 8 ah. 8ah is almost depleting those batteries.
If you keep your ride time to something under one hour, you might be ok. Even then, the life of those batteries will be cut pretty short.
If any of this is wrong, I'm sure it will be corrected.
