What are Ohms core features?
Ohm's core features are it's low weight, long lifetime, superior cold weather performance, and it's
environmentally friendly design. It weighs six pounds, lasts about twice as long as the average
lead-acid car battery, works in temperatures as low as -40C, and contains no lead or acid.
How does Ohm work?
Ohm uses EDLC supercapacitors to supply a high burst of energy to the car's starter. It also uses a
small array of Lithium Iron Phosphate batteries to keep the supercapacitors charged when the car
engine isn't running. These two systems are monitored and controlled by intelligent electronics
that ensure optimal performance over the lifetime of the device.
Will Ohm work with my car?
Ohm's dimensions are 9.0"x6.8"x6.8", and will fit Group 35 batteries. It will also fit in most cars above Group 35, but may require some extra fixturing.
How do I install Ohm?
Ohm is a drop in replacement for your existing car battery, and it's installed in the same way.
Simply remove the positive and negative leads from your old battery, drop in Ohm, and reattach
the lead to Ohm (red/positive lead first to prevent sparking). Make sure to tighten the mounting
harness to prevent Ohm from moving during normal use.
Can I buy Ohm if I live outside the United States?
We ship worldwide for an additional $10 fee. We currently are taking orders worldwide, but there may be a delay for Ohm to ship to certain countries. Please consult your national customs office for specific duties and tax rates. Ohm is not responsible for any import taxes, duties, or brokerages fees which may be incurred on your international order shipment
What are the advantages of supercapacitors?
Supercapacitors are excellent at delivering energy very quickly. They're also lightweight and perform better in
colder temperatures than most batteries.
Is Ohm safe?
Yes. The supercapacitors used in Ohm are mostly carbon and will not explode. The batteries are LiFePO4, which are
very stable and are used in some electric vehicles. We don't ship anything we're not comfortable with our parents,
brothers, and sisters driving with.
How long can I run my stereo or lights on Ohm without running my engine?
Ohm's reserve capacity is 10 Amp hours. The amount of time Ohm can run your auxiliary electronics without running
the engine depends on the amount of current your devices consume. The typical car stereo consumes about 15 amps, which
means that you could run it on Ohm with the engine off for about 40 minutes. If you forget to turn off your stereo or lights,
Ohm will automatically shut itself off to conserve enough energy to ensure you can still start your car.
What is your refund and cancellation policy?
You can cancel your order and get a full refund anytime before shipping. Ohm will likely change before its release as we improve performance and consider input from our first users. If Ohm isn't all you thought it would be when you get it, you
have 30 days to return it. If you choose to do so, you'll be responsible for shipping fees.
When will I get my Ohm?
Ohm is currently planned to ship in early to mid 2016.
