That charger doesn't have a LiHV mode compared to newer chargers. How did you set that up for 40amp charging then so the cutoff voltage, etc was correct?
I really learned some things from your video. Great job! Im starting No Prep, and it looks like the i charger is the one to have. But cycling the batteries at high amps shorten the lifespan if the batteries? Also will I see a big difference in running a two gear diff in my No Prep car? Thanks. .
Great info. For clarity, at the beginning of a race day, how many times do you cycle a pack before running it in the car? And do you cycle between each run? Cheers.
Hi, with the LRP Lipo 8100 mah-HV 1/12 Ultra LCG G-4.1 - 3.7V is 4.2 volt or 4.35 end voltage? I think for BRCA rules in the uk, it is 4.2 but is that fully charged or is 4.35 volt a full charge ⚡️ thank you for input and sorry for the questions 👍
I have started using your method of charge/discharge and noticed that my race pack during discharge cycle heats up to around 135F. Is this normal going from storage to 3.3V/cell? After discharge, I let it cool to about 100F before charging at 40A. Curious to how you monitor and control heat during charge/discharge cycle. Cheers.
Yes. How are your IR? Batteries peak performance is usually around 100deg. I never let them cool between cycles. Immediately recharge. You don’t want them to sit below 7.4/7.6v low cutoff voltage for long or they could be damaged.
@@klinikrc3823 My IR is around 1.8 at charge end. I have been letting my packs cool from 135F+ to just under 104F after discharge cycle and before charge (as per Alexander Hagberg's suggestion). However, I think I may get better performance (lower IR?) if I just go immediately from discharge to charge even if my pack is over 135F. Any additional thoughts or suggestions? Cheers.
