reading the artical about battery chargers in the July edition of Practical caravan (page 134)i was astonished to think how Inadequate our chargers are especially as more of us are using heavy drain items such as motor movers etc. to this end i thought it wise to change ours to a more competant unit. The one of choice in the article appears to be "nordelettronica's two- stage NE 143.Does any one have experiance of this charger or the companies web site please.Shane
