| How to discharge LiPo for storage
Sorry, I searched and read so much my head is spinning... My LiPo battery charger does not discharge, it only charges. So how does or what does a newbie do or buy or whatever to discharge his battery (easily) for storage? Battery is 5200 mAh 2S 50c 7.4v |

Simple answer buy a charger that has storage functions. Nothing else is convenient. Sent from my SM-N950U using Tapatalk |

Put it in your truck and drive it until it is at the voltage you want to store it at?

Charger is a simple Dynamite Prophet Sport Mini - no discharge function. Maybe something like: Targerthobby 3 IN1 50W Discharger Voltage Tester Balancer For Lipo Battery https://www.amazon.com/dp/B01ET162I4..._JfnaDbHQK0DH8 |

I have one of these ISDT dischargers. https://www.amainhobbies.com/isdt-fd...fd-100/p700374 Pretty much every charger these days has an incredibly weak discharge function, 1-2 amps at most. This take forever if you have high capacity packs. The ISDT discharger can do 2-3 cell packs at 6 amps so it is much quicker but not so high that it is going to throw off the balance of the pack too much if there is a weak cell. The voltage cutoff is adjustable with an optional PC link but out of the box, it brings the packs down to storage charge level. |

Yes, best to just run it down then if you don't have a charger capable, or if you don't want to purchase something new

Those battery balancers that don't charge can take a long time to balance the battery, and what if the voltage is off. For twice the cost you can get a skyrc b6 mini that will do everything you need and more. Only thing it won't do is check IR.

https://www.ebay.com/itm/Genuine-SKY...oAAOSwN3NcP-pW and it's quite affordable, but how long (guestimate) does it take to discharge (to storage) a fully charged 5200 mAh 2S 50c 7.4v battery at a max of 2 amps? | |

Bout an hour, maybe hour and a half. But also less chance of it heating up as well, so safer. I run it on the desk next to my computer. Easy to spend that much time there. Sent from my SM-N950U using Tapatalk Last edited by Voodoobrew; 06-15-2019 at 10:30 PM. |

Storage charge is about 40-50% charged. So assuming that 60% of the charge has to be removed from a fully charged 5.2Ah battery at a rate of 2Amps: Discharge time = 0.60*5.2/2 = 1.56hours | |
