Because I gave zero fucks for how actually useful the battery life was, I just wanted the hotspot to turn on again after the LiPo swelled up so much the pogo pins lost contact. NiMH AAs were onhand in abundance for flashlights. They had enough voltage to let the thing turn on and weren't going to catch fire, problem solved. Left it that way for years.
