I'm looking for a simple Li+ battery simulator, for testing charging circuits. I don't need anything fancy, and don't even need to measure the output precisely. I need more of a dummy battery, in order to keep the charger trying to charge. Something which simulates a half-charged cell, and will simply dissipate any current sourced by the charger.
Does such a thing exist, or do I need to buy a full benchtop load/simulator?
Thanks!
