EZ Peak Storage Charge Mode ??

[R/CBoatGuy]

Just got a new EZ Peak single output charger and an Id 2S 5800 Lipo pack, quick question about the storage mode charge setting. The other night I charged the pack up about 3/4 charge (that's all I had time to let it charge), then only got to run my 4tec 2.0 for about 5 or 6 minutes so I know I didn't run the pack down very far in its charge. Since I won't be able to run the car for a week or 2 I put the pack on storage charge mode, a full 2 hours later it was only up to the second LED on the charge duration and since I had to leave I had to shut it down. Why would it take well over 2 hours (possibly 3-4 hours) to charge (or discharge) on storage mode?? Even at a 4 amp rate?? Just curious...

Can't give you the tech answer, but that sounds totally normal.

It takes alot longer to discharge a battery than charge a battery with the ezpeak. Fear not, it should only take about an hour to fully charge the battery. Discharging is a different story, you'll want to either drive the car some more or put it back on the storage charge so you don't kill the battery.

it's alright son, I'll fix it

My fully charged 6400 onyx 3s used in my old slash 4x4 I had discharged using the charger from full capacity and it took about 18 hours. I honestly don’t recommend the feature because after doing this again a few months later it actually discharged my battery to a point where the charger would no longer accept it as it was under voltage

Thanks for the replies, i figured it was ok but i didn't want to take a chance ruining the pack just in case. I'm not new to lipo's, i have a bunch of 2S and 3S set's that i use in my R/C boats and charge with an Onyx charger, i'm used to seeing the voltage read-out of each cell during their charge cycle. The Onyx doesn't have discharge feature however. With the boats, a 5-6 minute run time is normal and takes the packs right down to the LVC, then i just bring them back up to about half charge for storage (going by the voltage read-out). Even tho i dabbled with R/C cars years ago, i'm definitely a newbie to the R/C car world!

Yeah just be patient,,,it’s worth the wait vs doing harm to you or the battery,,,,it’s an excellent unit and sooooo easy to use......have a blast......tazzzz

Cells may need to balance as well as the amperage being only 1a max if memory serves me right. It takes a while for this to happen if you have a decently large battery. Totally normal and nothing to be alarmed at

[lotust251]

yes if you try to use the store mode on a traxxas charger with a near fully charged lipo it will take hours on larger batteries.

Funny I was just about to start a thread on this very subject. I recently just got back into RC's but had never used lipo's before. I have the EZ Peak Live and two 3s 5000 packs. I've done some reading on them and saw that you're not supposed to let fully charged lipo's sit unused for extended periods of time. Anywho, my packs were fully charged today but I realized I wasn't going to be using them for a few days so I storage charged them. It must have taken at least 6 hours for the two. Glad to know that's normal. They've got to be joking when they say not to leave them unattended while charging lol.

There not joking.. things can happen when batterys charge.. go watch some youtube videos of charging gone wrong . . . good way to loose your house.


And discharge the battery in your rc car or something down to LVC then put it on the charger for storage won't take much more then a 1/2 hour or so.

With a discharge current of only 665mAh (750 for the dual) I can see it taking so long to do so.

I bought a Lipo bag to charge it in. I was charging it in the house, but after doing some reading I'm charging in the garage now. I just don't wanna stand down there in the cold staring at it for hours.

Unfortunately for me, I don't have a garage. I live in a condo (thankfully, ground floor of 2-level building), and the closest we have are carports. While there is an enclosed patio, and an outdoor double-outlet, it (also unfortunately) doesn't work. As such, I have no choice but to charged my LiPos (for Rustler, as well as for Typhoon H drive) inside. I used to charge them on the kitchen counter (engineered granite), but my wife started getting irritated...so I switched to charging them on the guest bathroom counter (engineered marble). Not sure if the bathroom is any better than the kitchen, but at least my wife stopped complaining, which saves me a few headaches each month.

I'm new to the lipo batteries and chargers and am using the Traxxas Ez Peak. After chaging then using the battery I'm not planning to use it untill the next weekend. I've put the bettery on the charger and put onto store mode and pressed start. Is it normal for the LEDs to light up the same as if it were charging? The LEDs lit up from 1a 2a 3a 4a untill the audible sound alerted me. Is this correct for storring the battery?

Yes. You are fine.

[T8R]

Yes. You are fine.

Thanks that's a relief, I didn't feel like having my hoise burnt down.

Great info. guys. Thanks.

I had exactly the same issue but with a 3S 5000 LiPo pack. I fully loaded it, used it on my trx-4 for 20 minutes and then put it to store. It took like 2-3 hours!

I use storage mode on all my batteries after any use where I wouldn't use them again for over 48hrs. I always discharge or charge in lipo bags (Actually I have one big one and multiple small ones (the big one holds four small ones and the small ones hould 4-6 batteries depending on size). The big bag has a hole for the wires to come out for charging.

For my larger batteries, it does take quite a while to discharge on my Dual EZ-Peak and smaller batteries less. I have never had an issue with the charger over-discharging -- it stops when it is at the right voltage.

[olds97_lss]

Kind of surprised traxxas hasn't come out with a purpose built discharger by now. One more thing they could sell for a likely decent profit.

You can get dischargers as well if it's an ongoing thing, like if you charge up 10 packs for a bash day and repeatedly only run down half of them in trucks due to breakage. Then your stuck waiting for days discharging on your charger.

I only know of one that balance discharges that should be reliable:
https://www.amazon.com/Discharger-In.../dp/B07ZD2D8YW

These just discharge, but do it at a decent rate:

https://www.amazon.com/Control-Disch.../dp/B082WC3NM4
https://www.amazon.com/SKYRC-BD250-B.../dp/B087NFJN67

I bought one of these to try out, seems to work well, but I keep an eye on it:
https://www.amazon.com/CellMeter-Bat.../dp/B07LDWK1FN

Seems to work well and drains a 4S 6200mah lipo in 40 minutes or so down to 3.75V, then I put it on my charger to bump it back up to 3.85V for storage when the main draining lights shut off. Waiting for it to trickle down after the lights shut off takes forever because it only does 5W I think internally.

I "modified" it so I didn't get blinded by the lights and so they don't touch stuff, or I don't touch them. Totally hack, but works for me:

I just charged two 2S Lipo 5000mAh Traxxas ID batteries, taking 40 minutes from get from "store" charge to full. I used one battery completely but the other only partially. Using the Traxxas balancer to check, that partially discharged battery was saying it was 88% full at 4.09V per cell. Using the store function on the iD Plus charger, it took just on 4 hours to discharge from 88% / 4.09V per cell, down to the store voltage. I was "supervising" the discharge process, thinking it would not take too long.
