Thanks everyone for your helpful advice. I'm going to give the diode method a go over the weekend - if I can get my hands on the diodes easily enough. the alternative was to buy 2 x 2V SLA batteries - but at $A31 each it seems like an expensive option - especially since I've already got 6V and...

Hi, Thank you for your reply. The load is basically an induction coil (just for demo) - throwing sparks only 2-3cms. The issue is that I have several 6V and 12V SLA's - good for the "big" coils, but some of the smaller coils only need 3V or 4V. The constant voltage is not critical - hence...

Hi, firstly apologies for what might seem like a 'basic' question, but I've been trying to work this out for a while. I have a sealed lead acid (SLA) battery - 6V 4AH. I would like to use this battery to power a 4V coil (for a display) - that is capable of (potentially) drawing the full...
