Joe,
There is actually a difference between the PL 5000s and 5300s, and the at pattern power levels, the 30C 5000s are not much different than the PL 5000s for power (based on the single set of 30C packs I have), but do run 5-10F cooler.
This spring I picked up new sets (5s x 2) of:
TP ProLite V2 5000s (~1195 grams, 20C continuous),
TP ProLite V2 5300s (~1195 grams, 20C continuous),
TP ProPower 30C 5000s (~1300 grams, 30C continuous)
The V2 5000s definitely have more zip than the 5300s. I recently did some logging with the ICE 80 HV.....folllowing numbers are preflight static runup, full throttle in air prior to entering the box, full throttle just after the sequence, and postflight static runup -
5300s, flight 41
Amps - 90.0 / 83.3 / not measured / 78.5
Volts - 37.0 / 36.4 / not measured / 34.8
3880 mah used for P11 sequence (TP1010 recharged about 3500 mah)
Ending temp around 120F
5000s, flight 46
Amps - 94.7 / 89.0 / 79.4 / 80.0
Volts - 38.0 / 37.2 / 34.5 / 34.4
4860 mah used for F11 sequence (TP1010 recharged about 4300 mah)
Ending temp around 120F
Both of these sequences were big and fast in pretty strong winds, 90F ambient, and the 5000s did not dip below 36 volts until after 4000 mah was discharged. I can't explain the difference in mah between the ICE log and the TP1010 charger, but I believe the 1010 to be more accurate (it correlates pretty well with my Eagletree, which is typically a tiny bit lower for mah). And these numbers are pretty representative of other packs I have, the TP stuff is nothing if not consistent.
Regards,
The max current reading logged (90 A and 94 A) exceeds the max current limit allowed by CC ICE 80HV (80 A) by more than 10%. Should the high throttle be lowered a little bit?
Limiting the throttle will not solve the problem. The readings we get on the meters are an average current. The ESC works by allowing full current to run to the motor in pulses, and throttle controls the rate of the pulses. Using the throttle to regulate the current will still let the full 94A or whatever get to the motor, just not as often.
However, if you are running 94A intermittantly, maybe it's OK for the ESC. I talked to Castle and they had me turn off my current overload protection since I fly F3A. We don't use full throttle that often, and I think the rating is max continuous current. Just double check that one as I'm fairly new at this.
