12.8 volt 20ah lithium lifepoe4 battery box. Has 10 amp fuse installed inside. The case has some weathering on it but other than that it’s a great unit. The battery can put out 10 amps. I never tried to connect a trolling motor to it. I’m not sure how many amps the small ones take. This battery is rated for somewhere around 3,000 cycles. I maybe cycled it a max of 50 times.
