I incorporated one into my battery box along with a 350W inverter. It's a model 3300. I have sold a bunch of these in my store and haven't had ay problem at all with them. They work really good on the deep cycle batteries and the gell cell or the AGM (absorbed Glass Mat) batteries.
I can ship it to you. You can pm me and I will give you our phone number and the shipping price. The charger retails for $69.95 plus tax approx. $5.70 and $8-$10 freight.
Or you can check with your local Carquest or NAPA store.
