you can get them cheaper than this btw
my 70/80 ah s/h $30 battery does a reasonable job
I take it camping to run two small lights and also use it lightly
to run the fan on my scope and when needed a small 12 v hairdryer for dew control.. I try to draw as little as possible from it specially when the hairdryers out.. the nice thing about the box is its very portable.
yeah I guess its only good for a couple of nights, but I find thats enough to get buy with.
I recharge with one of these as my worst experiances with wrecking batteries is nearlly always been overcharging.
