Squid Posted March 19, 2019 Share Posted March 19, 2019 Depends on what the specs of the battery are. Not enough info to even begin to answer your question. Link to comment Share on other sites More sharing options...

FXRich Posted March 20, 2019 Share Posted March 20, 2019 your battery fully charged will put out 4.2V at 30A you can have a 0.14 coil. 3.7 is the nominal voltage the less the charge the lower the volts, the more it is charged the more the volts. You should build to the highest volts. http://www.steam-engine.org/ohm.html thotz 1 Link to comment Share on other sites More sharing options...
