Is a discharge bank needed?
 

I saw a i charger with a discharge bank for sale.
what is the purpose of this and should I get one as well?

Thanks

If you have no clue then probably you are no racer. Did you try the search because about dischargers there are plenty of topics to be found.

We all start out different.

I’ve never used one. Guess I’m not a racer

Everything you need to know is explained here:

True, but you have seen them, heard of them and/or even know what they do. But for him I advise the start is the search button on top of the forum list and do some reading instead of starting another new topic next to all others.

With 3 fresh questions in this electronics section which from all the answers easilly can be found I have a pretty good idea he did not even gave it a try to find some answers by himself.

A designated discharger is very beneficial.. I've pre charged 2 lipo only to be run out by rain a hour later.. a discharger can make storage level way faster and easier than a charger.. bulb .resistors is way faster.

Understanding Lipos more important. Doesnt matter to a racer or Basher. Earier when lipos are out with the Airplanes. Minimum voltage was 2.8-3.0v, you were fine. Now a days you ESC cut out set to 3.2v. Way before 2.8-3.0v. New charger now have more brains than any of us RC'er!!! Stop when its is safe charging, discharging, and storage. It stops at the beginning #of cells, and voltage. View do's and don'tt of lipos.

Yes. Nothing to do with RC all to do with good lipo battery care.

this is NOT how you foster a desire to learn.....anyway.. ryan harris does a good job of explaining the benefits of these technologies.. but for the most part dischargers are used to rapidly discharge, then rapidly charge batteries to keep them nice and warm.. like most things batteries have a optimal opterating temp, and with batteries their resistance will be lower at this temp than when cold.. whether your club allows this is completely region dependant as it CAN induce a higher risk of lipo fires.. and it will shorten the max lifetime of the cells. so i dont think its somthing to consider for club racers and stuff.. but if you are going to a national, and can run 5 minutes with no warmup on track, and not hit anything while running 95% or higher average consistancy... then its a benefit..

i will also add the point that say you charged two batteries for a bump.. its not ideal to put the fully charged one in the box and leave it there til next race.. often many chargers has pissand discharge rates. so a rapid discharger will help you to get it to storage voltage while you are still at the track.. higher end chargers with that discharger option are quite useful for versatility. this will be my 11th year racing and ive never felt i was disadvantaged against the guys who do all that battery business.. i just plug in a $100 charger and put it in my car when its done.. but i guess im not a RACER either then....

if im gonna be hyper honest, getting your TIRE prep, car setup and driving style sorted will help you a million times better than extra crap on your desk...

So you think all the students making school exams need a team to give all the answers? The students will not learn a thing while taking the time, do a lot of reading the school books and search articles on the internet does give them knowledge.

Also with a bit of thinking about the user asking ths he is no racer. Does a basher need to get the max out of his battiers with a discharher while most of them already run their batteries empty?

I’ve seen others use them. But haven’t seen any advantage to them. If I ended up with a battery charged, I’d either run it after racing, at home, or just wait till next race. Which was usually only a week away. I’ve not seen any effects from leaving a battery charged.

We use our discharge bank for 2 purposes. Yes, I cycle batteries. Just part of my process and I lose that advantage the first time I wreck.

Now that that is out of the way, it also makes quick work of storage charging my batteries. Between my kids, myself and my wife, we have 6, soon to be 7 batteries to put into storage mode. If I had to do those on my protek 610ez, it'd take all week. Using our icharger and discharge bank, they are done pretty quick.

I also have a skyRC BD250. It can get stuff into storage quickly once you figure out the cutoff voltage that'll give you the desired storage voltage after rebound.

We don’t need anymore Search Police in here, it’s more annoying than people who are not searching

Who is "we" or are you only talking for your self? I even did pinpoint him to any infomation, you did not gave any answer.....

I did make a discharger (topic can be found with some search) and did notice the power over the whole run did become more consistent.

Leaving Lipos charged is the number one thing that hurts them tied with over discharging. I think race grade packs are far better at dealing with it, but you don't find serious racers leaving packs they care about fully charged from week to week. If you accurately track IR's you'll see them degrade by doing that. Puffing is extremely likely as well.

I'm pretty sure cheaper packs are far more failure prone to damage in general, just being lower quality cells.

Proper lipo care helps them last far longer than just leaving them at whatever charge state between runs. I'm at the point where I put my packs at storage voltage (3.8-3.85v) or post run do a balance "charge" where the charger just uses the balance circuitry to make both cells perfectly equal.
