When I ran 17.5 TC we would run a cycle charge/dis/char I had no delay all at 40 amps. My packs would be about 110-120 degrees at best but the IR's were 0.6-0.8 per cell all the time. Didn't hurt the packs at all.
With that in mind I now run MOD tc 5.0 turn and my packs after a run are 130-140 degrees.. So the pack is getting used much harder in mod then it was with all the 40 amp charge and dis charge...

Before a race, I discharge at 30A when my IRs are high (usually in the 4 oHms and higher range) when it's back down to 1.5ohms ... I just charge and don't do cycles in qualifying and the main. BTW... I race stock.

wow... what batteries are these? Never had a pack that has IRs that low after cycling even multiple times. Does it fade after 7 minutes?

My fantom packs were that low when new, and will still get to around 1 milliohm per cell when cycled properly. Typically fade at 7 minutes isn't even a thing unless you're running 1/12 scale or VTA since most races are 5-6 minutes.

never had luck with Fantom batteries...motors are good.

I want to switch over to this higher amp charging . Can I get away wih just the charger and power supply or do i need the discharging bank?
What is the benefit? Quicker discharging?

Higher discharge rates lower internal resistance. High charge rates will help lower it, just not as far as it would if you used high discharge in combination. The charger will do 30 amps on a 2s pack, no extra equipment required besides a power supply.

without a discharge resistor you will maybe get around 4 amp ... to get 30 amp discharge you will need a resistor or use a lead acid battery

high amp discharge all it does is heat up the pack you can also lower the resistance with a lipo warmer set no more than around 100-104 degress. keep the battery warm while charging will lower the resistance with out the high amp discharge abuse

Heat wears out the packs as well. performance costs

I agree with you

"30m" as in 30 minutes?

hanulec

Yes 30 minutes

Always test it with an old pack first ..

guess we don't need warming sacks for lipos in Florida, its always 90-100f lol
