You should only use LiPo Amigo boards to charge 3.7V LiPo or LiIon batteries, and you should make sure that any project involving LiPos is sufficiently protected from being dented, bent, punctured or crushed.\u003c\/p\u003e\n\u003cp\u003eWe recommend only using LiPo batteries that have own internal protection against overcharge, over discharge and short circuits (all the ones we sell do).\u003c\/p\u003e\n\u003cp\u003eIf you're using a battery bought from elsewhere, \u003cstrong\u003edouble check that the polarity of the wires matches the markings on our board\u003c\/strong\u003e (red to + and black to -) before you plug it in!

Don't do this if you're using an unprotected battery.\u003c\/li\u003e\n\u003cli\u003eThe battery protection IC on LiPo Amigo Pro limits charge and discharge to about 1A. The pads marked NO PROTECT can be bridged to disable this (no protec, only attac). Only do this if you're using a battery with its own protection that can handle the higher discharge current. We wouldn't recommend trying to draw more than 2A from the battery, as this is the max rating of the JST-PH connectors.\u003c\/li\u003e\n\u003cli\u003e** You should only use the DEVICE connector on LiPo Amigo Pro for powering devices that can handle 4.2V - that's the maximum potential voltage that can be supplied by a fully charged LiPo. Don't plug in things like micro:bits that can't deal with LiPo voltages!\u003c\/li\u003e\n\u003cli\u003eThe DEVICE connector draws its current from the attached LiPo so it will only provide power if a battery is plugged in. There's no boost circuitry on board, so it won't power Raspberry Pi computers or other devices that need 5V.\u003c\/li\u003e\n\u003cli\u003eFor connecting your device to LiPo Amigo Pro, we'd suggest using this \u003ca href=\"\/en-eu\/products\/jst-ph-2-pin-jumper-cable-100mm-long\" target=\"_blank\"\u003edouble-ended JST-PH cable\u003c\/a\u003e or this \u003ca href=\"\/en-eu\/products\/jst-2-wire-assembly?variant=711377809\" target=\"_blank\"\u003eJST-PH wire assembly\u003c\/a\u003e.\u003c\/li\u003e\n\u003cli\u003eBecause we hate leaving unused space on our PCBs, we've broken out a bunch of other headers that you might find it useful to solder things up to.\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eThe LED headers can be used to connect up an external LED to show charging or on\/off status - useful if you're building your battery charger into an enclosure.\u003c\/li\u003e\n\u003cli\u003eThe SW headers can be used to add an external momentary on\/off switch to enable and disable the power output of LiPo Amigo Pro.
