    3-5c break in discharge

    Thunder Power, in their battery instruction sheet, recommends to discharge their batts at 3-5c for the first few cycles. Correct me if I'm wrong, but I don't think that can be done in the boat. Does anyone have a low cost method of discharging batts at this rate? I have an E-flite inline Power Meter which will tell me amps and volts, but what is the best thing to use for a 3-5c load? Lights? Resistors? Any help would be appreciated- thanks.

    I put a few cycles on them with my charger before use, at .5C charge 10A discharge, It is less than 3C for most cells as my charger only goes up to 10A discharge, but it has to be better than hitting them hard right off the bat.

      What kind of charger do you use?

        Mainly a Fusion 702b Emperor, but I also have an old Schulze 330d and a Hyperion 1210i that get used infrequently when I am desperate.

        I have just been reminded that although the fusion does 10A discharge it is to a maximum of only 50W, so though I set it to 10A for all my packs it never actually gets up there, 50w is 6.75A on 2s and 4.5A on 3s which is almost exactly 3C for my Minis which use 2S 2200mAh or 3S 1500-1800mAh, and 1C for my bigger boats as I run 2s 6600mAh, 3s 4500mAh and multiples thereof.
