Does anyone recognize this thingy? It's connected between a 18650 Li-ion battery and a bt speaker. The speaker works for no more that half an hour before shutting itself off and I believe this here is the culprit, given I've tried all the 18650s I have and none of them seem to drop even a tenth of a volt after the chink voice tells me the battery is low. Am I wrong, though?
