Outside of just doing an in-water test, how do you burn test your DPV batteries? Resistor bank and voltmeter? Looking for a way to properly burn test my DPV at home with either a DIY solution or something off the shelf if a company makes a tester. I have a DiveX Piranha (non-PTB) but would also hope the tester works with other DPV models if I decided to upgrade/buy another.
