modality - a method of therapy that involves physical or electrical therapeutic treatment. rehabilitation - the treatment of physical disabilities by massage and electrotherapy and exercises.
An AA battery is a 1.5 volt battery so if you connected 8 together in series you would have the 12 volts, but you would have no where near the amount of amps necessary to turnâ¦ the engine over.
In most cases, youâll be using an 18650 battery, and the usual 10 A rating will be more than adequate. Using ohmâs law (I = V/R, or amps = voltage/ohms), you can see that even for sub-ohm builds of 0.7 Ï, 4.2 V would lead to 6 amps of current, which is still within the capabilities of most large batteries.
