I am making a small, portable charger that is going to use this 400mAh battery (http://4tronix.co.uk/store/index.php?rt=product/product&product_id=508). It is going to be an emergency charger. I cannot find a circuit board that will work to make a charger.
Does anyone know a circuit board that I could buy for this?
