Here is a smart car battery that does not need jumping. The Ohm battery is a reliable battery that lasts twice as long as the average lead-acid battery. It keeps you from accidentally draining your battery. It also turns itself off when it gets critically low. Ohm regulates itself to prolong its lifetime.
Ohm’s supercapacitors are designed to work well in low temperatures. Installing it easy as well. Just disconnect the terminals, drop in Ohm, and reconnect. Like what you see? You may want to support the project on Indiegogo.
