WELL CONSTRUCTED . ARRIVED SAFE , NOT TESTED YET , WILL TEST AND REVERT
excellent product it does what it's supposed to do. I would not recommend it using on lithium batteries and leisure have a smart charger otherwise for lead acid battery or efb or AGM is perfect. really good and it's good for if you're designing a backup system. for my purpose I have removed the transformer as I wanted to be powered up from the low-voltage side and that is going to be the sensing side for to switch on the relay on and off when it reaches it's low threshold and switch off when it reaches it's maximum threshold voltage.
