I design battery adapter to use DIY Bosch cordless tools with Bosch professional battery. It is only 18V because inside adapter I use resistor to set 18V tool variant for DIY side. Temperature information is connected from battery to tool. Due to it is possible to charge professional battery from DIY charger ;o) It is made from old DIY battery..
