    • Do you have to break in a new Lipo ?
    • Is storage change needed, if you fly every few days
    • I have read to follow the 80% rule. Drain out no more than 80% of the lipos capacity. Correct ?
    • If I storage charge do i keep them in the fridge ?
    • If the packs are really warm do they have to cool down before i charge them again ?

      Its cool man!

      I only store my packs in the fridge during summer, but make sure to take them out at least 5 or so hours before charging so they can get up to temp

      The fridge is good if you are not going to use them for awhile (3 months+) but make sure when you take them out you leave them out for a full day to get back up to room temperature before using them.

      If you have over discharged the battery, putting them on a slow (1-2C) charge can actually help cool the batteries much more quickly. In an over discharge scenario, the batteries will actually keep heating for quite a while if you do not put them on a slow charge

      I wouldn't have believed it if I hadn't seen it. THey were som old practice packs for a pro, he beat them to the point of puffing, smokin hot. We threw them on the charger at 2C, and they cooled off quite a bit quicker than they would have otherwise, and they weren't heavily damaged. They were in the 3.2V/cell range after a 3:45 flight

      I wonder if the batteries are cooling because its reversing the direction of power flow just experienced after a heavy discharge. Interesting and good to know to say the least.
