nimh batteries vs lipo

Li-ion battery has high energy density and decreases in capacity after many cycles, but the battery safety is worse than NiMH batteries, and the Li-ion battery pack must be used with circuit protection module, because overcharge and over discharge are fatal to Li-ion battery. Due to the addition of circuit protection module, lithium batteries will generate a certain electromagnetic interference, so for products sensitive to electromagnetic interference, if you want to use lithium batteries must do a good job of electromagnetic isolation. The safety of NiMH batteries is much better, usually without circuit protection module, and not easy to fire and explosion, but the disadvantage is that it will be more bulky.
