So I asked awile ago what motor controller to use with this motor:
Rich answered: "Looks like it's 1.0 Amp @ 12VDC so the 2.5A L298n H-Bridge will be OK for it."
But I didn't ask what kind of battery I should use with it.
What I need to know for the battery:
Good kind of battery that lasts really(and I mean really) long.

Motor is 6-12v so use a battery that can supply 6-12v
Motor is 1A at 12v so use a battery that is rated at 1Ah if you want it to run for 1 hour before recharging, or 20Ah battery if you want it to last for 20 hours. etc.
Battery is entirely up to you. LiPo are light and have large capacities, a 2S 5000mAh would work and last 5 hours. SLA batteries are heavier but have large capacities, a 12v 9Ah would last for 9 hours. This is all based on only the motor being powered, time will be reduced as the load increases.
