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.
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. .
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.
This is exactly the information I have been looking for! Thanks for all the great tips!
Oh and I absolutely love my Klinik titanium top screws!
Great info. I'm curious to what your charge/discharge/cycle method is today as this video is now almost 3 years old. Any updates?
Same technic 👍
I think the discharge is what’s crucial. My theory is fast charging isn’t what makes the difference

Just once to wake them up. After that, racing will cycle them 👍

Thank you!!! It won’t shorten the lifespan of good batteries. Cheap ones might not like it too much. Watch the IR’s
Now I understand why people spend so much money on chargers
Thanks for the video! May I ask you wich dyno you use?
Mini pro 👍

End voltage is regulated by your particular event 👍
I’m curious about the two gear diff I’m running an associated truck should I be pulling two of the gears out to free it up?.. thanks in advance.
Can you say how much of an effect you get just charging at 35 amp without the discharging cycle? So just the high amp charge in other words…
Not sure. We cycle up and down normally. I would guess half the benefit?

Is the amp rate for charging, Is that good for 1-6s lipos?
The LRP batteries can you charge these at 3C? Is it Graphene 4 that is current specs? For stock what would you charge and discharge at? 👍
Yes we cycle 35a discharge and 40a charge for spec class racing 👍
Do you do anything with manually ballancing the packs?
What do you mean?
Do guys in mod class do this as well?
May i ask the icharger or much more cell master which charger do you recommend for stock racing? 👍
Icharger 100%
How many amps do you think your motor is drawing while running the car?
On the dyno a 17.5 will pull right around 100a
Where can I get that battery heater box?
DRC makes them
電磁為何要加熱？？？
battery warmer 80 - 90 degrees C or F?
F
