Default Discharging question

Hello guys just want to clarify something regarding discharging.

After charging a pack fully are you suppose to discharge them straight away or cool them down ?? Some ppl say cool them down some say discharge them straight away

Im quite confused, you know how racers repeak there batteries before they race to get the best possible performance ?? Well isnt it the same as charging a pack and then discharging them 20Amps straight away ??

Im using 3300GP and Sanyo 3000HV. Hope you guys can help

Repeaking is just starting the charger over again to make sure the batteries are fully peaked before you go out on the track. Some people re-peak at a higher amperage. I don't.

Repeak as close as you can to the start of your race.

I also put the batteries right onto the discharger @ 20a right when I'm done with my marshalling duties.

try visiting the smc thread, i got all the info i have now from that thread.

by discharging after charging, what are you trying to do? are you tryin to cycle ur packs? if ur merely cycing ur packs, its better i you let the packs rest for a minute or two before discharging, its more gentle on the batteries as they dont heat up unnecesarily, remember too uch heat is not good for you bats.

however, if your racing, its better if you use the bats within 5 mins from thetime the charge stops as the discharge voltage is higher. Dont u notice, if you run a bat thta was charged the night before and then repeake don the track the pack is not as punchy as a pack that just came out of a charge?

well, hope my inoputs helped, gudluck!

Discharge right away or wait?

When I cycle my batteries they get discharged 5 minutes after they are done charging. After a a race I personally do not discharge them, I just put them away.

Later,

I think it would be better to disharge them immediately after running.

However, if they are too hot, I would wait until the batteries are cool before disharging.

You can also discharge while cooling the battery with a fan.

Hope this helps.

AMP Discharge rate?

Most chargers on the market today discharge at either 10amps or 20amps. Some can simulate 30amps i.e. ProTrak, but for the most part the majority of chargers on the market discharge at 20amps.


My 16 x 5 V6 discharges at 20amps.
