safety precautions
warning ! working with batteries is fun but be aware :)
1.) Do not let the red and black wire touch each other, otherwise the battery will short circuit.
2.) The batteries are loaded with power, do not directly solder onto the battery - use insulation tape.
3.) Always be to charge and discharge the battery with the correct voltage and ampere. Lithium batteries can bloat or even explore when charged incorrectly (always use a li-ion protection circuit and voltage regulator as shown below).
