2pcs 3.7V 1600mAh 1S Lipo Battery JST Plug Rechargeable for RC Racing Drone Quadcopter Helicopter Car Boat Spare Parts

Nowadays when it comes to portable electronic devices the most commonly used source of energy are so called lithium polymer batteries, or LiPo's for short. They offer a great volumetric and gravimetric energy density, and come in all sorts of shapes and sizes with different capacities and voltages to suit your application needs. It all sounds great, but the question is how safe are those if you accidentally overcharged or over discharged them or in the worst case even create a short-circuit Let's find it out. First off, I separated my batteries into single cell batteries with a nominal voltage of 3.7 volts And multiple cell batteries with obviously a multiple voltage of 3.7 All of the single cell types hid the terminals underneath a protective barrier of Kapton tape which I easily removed Three of those five lipos did not feature any protective circuit at all which means if you act stup
