Well i am almost done with the new batteries. There is a little bit of a problem with the bike basket swaying as it is not very strong but we are thinking that i could put the new batteries on the trailor.Fortunately my neighbour knew how to hook all the batteries up right and he used a car battery charger to test them. I have to get my own one. I haven't had a full right because of that sway yet. To put them into the trailor i need a longer cord so i am trying to do that now. I put the batteries in a sort of travel wheeling bag that i got for 95 cents from the local community centre secondhand store. they have great stuff there. Can't wait until i am done :0)
