Alright spruce I will have a look tomorrow
I had a look and couldn't see their class rating. Its always good to have an outside company test the performance of the batteries. (NCC Verified.) Sometimes the manufacturer can hype up their product.
As Jonny posted, it would be good to run a pump and electric reel if the manufacturers specs are right.
You will also need a 20 amp intelligent battery charger.
You also need to consider the weight. Its a beast. At 41kgs its heavy. If you have to take the battery inside for charging then you must consider this.
