I point them to <a href=\"https:\/\/www.multirotorsuperstore.com\/lipo-break-in\">this guide<\/a> I found on <a href=\"https:\/\/www.multirotorsuperstore.com\/\">multirotorsuperstore.com<\/a>&#8216;s website.<\/p>\n<p>Break-In Procedure:<\/p>\n<ul>\n<li>First Charge of 0.5c up to 100%<\/li>\n<li>First Discharge at\u00a00.5c to 3.7 volts \/ cell<\/li>\n<li>Second Charge of 0.5c up to 100%<\/li>\n<li>Second Discharge at\u00a00.5c to 3.6 volts \/ cell<\/li>\n<li>Third Charge of 1c up to 100%<\/li>\n<li>Third Discharge at 1c to 3.6 volts \/ cell<\/li>\n<li>Fourth Charge of 1c up to 100%<\/li>\n<li>First flight with moderate current (gentle flying) to about 50-60% of discharge limit<\/li>\n<li>Fifth Charge of 1c up to 100%<\/li>\n<li>Second Flight with moderate current (gentle flying) to about 70-80% of discharge limit.<\/li>\n<\/ul>\n<p>So lets get some terms out of the way for those that don&#8217;t know. C means capacity. So if you have a 1300mah battery 1c is 1.3amps, 0.5c is .65amps. How do you know where the discharge limit is? Get a current meter and fly based on current used (mah used).<\/p>\n<p>&nbsp;<\/p>\n<p>So I do not follow this guide exactly. I actually do a lot more cycle before I fly the batteries. I typically have them doing charge \/ discharge cycles for about 48-72 hours. Is this overkill? Probably. I do 1-2 times at 0.5c\/3.7v, 1-2 @ 0.5c \/ 3.6v, then about 5 times at 1c \/ 3.6v, and then another 2-3 times at 1c charge \/ 5c discharge (or the highest your charger allows).\u00a0Following all that I do about 4-5 flights gentle around 50-75% discharge then I start to hammer on them.<\/p>\n<p>Now does all this even matter? I don&#8217;t know&#8230; I am not a battery chemist. I just know that the batteries I have seem to last a bit longer than most. I also know they don&#8217;t get too puffy until I start abusing them where as the batteries I had when I first got into the hobby they were destroyed within 20-30 flights.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When I get a large amount of new batteries in a lot of people ask me if the batteries need to be &#8220;broken in&#8221; or not.
