Storage Charging RC LiPo Batteries | Quick Tip | Motion RC

Storage charging is imperative to keeping your LiPo batteries healthy and helping them last much longer. Links to all products below:

The 4.0 amps on the screen (which you correctly said was the 1C rate for battery you used) is the charge rate if the battery is somewhere below the storage voltage value. It is not the discharge rate. That particular charger has a discharge rate of 0.1A-5.0A, but it can only disspate 36 watts per port. If you put a fully charged 6 cell battery on it, the discharge current can be no more than 1.43 amps (36 watts / 25.2 volts =1.42857 amps). A fully charged 2 cell battery would discharge at about 4.29 amps (36/8.4=4.2857).

Great advice to anyone who is just getting into lipo use.

Key word “religiously” I’ve heard that a fully charged lipo after 24 hours the lithium begins to destabilize, it’s a slow death basically, I wouldn’t recommend anyone take that chance, I tend to charge and use my packs within a few hours or less, I have some lipos that are almost 7 years old and still balance out nicely, I keep a close eye on all of them and periodically load test them to confirm each of the cells drain equally, if I notice a significant diff in voltage drop I won’t use that pack, great to see these informative videos James 👍👍

The best video I’ve seen on the topic. Clear and concise. Thank you!

I have batts a few years old as well and they're fine.

Good video James!

Thanks for this video! I balanced charged a 3s battery for the first time and didn't do the setting for storage charging right and this video helped and now its storage charging correctly! Thanks!!!!

i have 4 batteries i stored in the fridge at 3.8v / cell for 4 years. checked them occasionally over that period and they never moved. brought them back into use last week and have noticed no change in performance or cell variability. take care of your batteries and they will take care of you!

Haha, the pressing left/right to see per cell voltages wins this video Video of the Day!!

I just subscribed this is the exact info I was looking for about the storage.
I was very unclear what the storage meant so I went into my Duo charger and saw that you could not change the storage any lower than 3.8.

New to LiPo batteries and you answered my biggest question. Will storage mode raise voltage as well as lowering it, automatically as needed? YES! Very good to know and will be my most go to function. Thank you for the insight.

Thanks for the video. Now, how about some options for discharging packs more quickly? Obviously flying a plane will do it quickly but that's not always possible once back at home with a number of packs needing attention. I devised a board with 4 - 12V, 50 watt incandescent bulbs w/sockets wired in parallel. Each bulb will draw up to ~4 amps of current. So having them all screwed down shows around a 16A - 17A load. I incorporate my parallel charge boards and my watt meter for this also, having each pack's balance plug plugged into the board. Then I use one of the cell meters with the alarms set to 3.8V. I unscrew bulbs to lessen the current draw as they near equalization, finally using a cell meter on each pack to make sure all is well before putting them away. Saves bunches of time when many packs need to be discharged. My setup, because of the 12V bulb rating are only good for 2S - 4S packs. If I'm just storage charging a pack or two I will use that function on one of my chargers but it is a slow process.

Thank you James, as always a great tip!!

[colinturner]

Didn't even know my charger had that function ... thanks!!!

[mikekixaxe]

Great Vid. ! So when it gets to 3.8V, Unplug and put it away ? will that charge stay at 3.8V for how long ? I guess im only use to Vehicle batteries where you can just plug it in a Maintainer and leave em plugged in for say the winter etc. for storage. thats a Nice charger you got there too wow ! thanks man !

[Hanmieson]

Thank you for this easy to understand video, helped alot.

[easystar]

Fantastic video and great piece of advice. Many thanks.

[JeffsCustomRC]

Great information and tips as always James, hope to see ya tonight 👊🏼👊🏼

[juansaladzar]

I have been using the same lipo for 31 yrs now brah 👍

[nicholasadams]

So a 1C rate for a 5500mah battery would be 5.5, correct? And my charger in storage mode will stop when it's complete ? Any help would be great, thank you!

[firewaffle]

Hi, if I just used my battery until the ESC cut it off, can I leave it at that cutoff voltage for more than 48hours?

This is actually for my RC car, I don't actually have a storage charger so currently I leave them at that cutoff voltage and then charge them before I drive the car.
