havey weight batterys

bought me batterys for the boat, 6 2v traction ones, they weigh a ton i nearly could not lift them in the boat, lucky someone else brought them for us as the car was right down with just 3 in. just hope that they fit in the boat with no problems now when it comes. Hoping it will be the 1st of october need to conferm it this week then the real fun starts. now got my eye on a cheap victron inverter now. :0)
