Re: Found a discharger that works! Hello Max: What you say makes sense. My iCharger allows selectable discharge amperage to any value that I choose. If you're only discharging at .5 Amps, it could take quite a while to get all of your batts, particularly larger capacity, to storage charge. Unless I have suspect pack or, cell, I only discharge my LiPos once a year, larger capacity at the end of the outdoor season and smaller at the end of the indoor season, so the wait to discharge to storage voltage wouldn't really be a great concern for me.

FYI, I will do 4 6S 5000's at once using my lightbulb method, but you HAVE to have a voltage alarm to warn you when you get to 3.8V/cell so you can shut it down. That is why I am looking for an automated system that will shut itself down rather than me having to constantly monitor it. |

Re: Found a discharger that works! I'm curious about the need for this item? I suppose that if your charger doesn't discharge as well, it has its place, but for about the same price, or a bit more depending on model, you can purchase an iCharger, which does it all. My personal charging system includes an iCharger 3010 powered by a 1000 watt Meanwell power supply. Up to 30 amps charge ability, to a maximum individual batt cell count of 10. Auto charge, discharge, cycle, storage charge - all batt chemistries - and very accurate. It is actually more featured than I'm capable of absorbing, Lol. Peter |

And except for my extraordinary good luck of a 3/4 inch plastic pipe bursting, I would have lost the entire house. I ordered one of these last Tuesday, and it is now in Lewiston NY where I will pick it up tomorrow. I know $115. seems like a lot, and of course with shipping and the Canadian dollar and the GST I will have to pay, it will be more like $200. Let me say that if $200 means I do not have to worry about a house fire it is money well spent. |

Re: Found a discharger that works! There are various Arduino based dischargers on the web and RCGroups. Or there is a commercial one available in 50W and 150W versions for $12.99US: http://www.myrcmart.com/rcx-3in1-bat...ng-p-4766.html http://www.rcgroups.com/forums/showp...&postcount=188 http://flitetest.com/articles/arduin...age-discharger Kevin |

Re: Found a discharger that works! Up to now I have been using lightbulbs and a voltage alarm. It has always worked fine for me. It just meant I had to be in the same room when I was discharging I like that gadget but its a bit pricey for a single purpose item.. Prior to this post I had an idea to arduino something a little more automated than my light bulbs and alarm method. An arduino module controlling a relay is what I had in mind. Only problem is Im not that arduino Savvy. Surely someone can cobble something together for arduino faster than I can and for a lot less than the 115USD those guys are selling that gadget for. |

Found a discharger that works! I've always wanted a proper dedicated lipo discharger and stumbled across this one. Found it threw Facebook and the reviews and videos sounded like it was exactly what I was looking for. So I pre ordered one (2nd batch) and it showed up a few days ago. Well today I went flying and my time got cut short, so I returned home with 4 fully charged 6s 1800ma packs. I threw all 4 on the discharger in parallel and they were safely discharged to 3.85v in less than 20 min :wow2: I'm not a rep or affiliated with this company, I just think alot of you guys will appreciate this post and will be interested in looking into this product. http://www.perfectregulators.com/Uni...Discharger-Pro     Universal Lipo Discharger Pro - Introduction - YouTube Universal Lipo Discharger Pro - Operation and Timed Discharge - YouTube Info from the website : No more using your charger to discharge un-used Lipo Packs to Storage Voltage. The Universal Lipo Discharger Pro is a stand alone, self contained Lipo Battery Discharger that will run automatically to ensure a proper and safe discharge. The Universal Lipo Discharger Pro has an input range of 2s - 7s Lipo Batteries, dual status LED's, dual Cooling Fans, large Heat Sink and most importantly automatically shuts off when storage voltage is reached. The Micro-Controller constantly monitors cell voltage to ensure that as soon as the set storage voltage is reached, that the discharge cycle is automatically stopped to prevent damage to the battery. Operation is extremely simple and there is nothing to press or a switch to operate. Simply connect the main battery leads, then connect the balance adapter. As soon as the balance adapter is connected, the Universal Lipo Discharger takes control. The dual LED status indicator will show when the battery is discharging by illuminating the red LED. While in discharge mode, the dual cooling fans will automatically start and run during the discharge cycle. When the storage voltage is reached, the discharge cycle is automatically shut off, the green LED will illuminate (and if connected, the Audible Alert will sound) to indicate the discharge cycle is complete. The fans will continue to run after the discharge cycle has completed to allow for quicker cool down of the unit. Simply disconnect the battery and connect the next one. If a battery is accidentally left on the discharger for a prolonged period of time after the discharge cycle has completed, the unit will completely shut off when nominal cell voltage reaches appx. 3.75v. This added feature prevents over discharge of connected batteries. Another feature is that the Universal Lipo Discharger Pro can discharge packs in parallel with the use of parallel adapters for the main battery power leads and balance leads. Current is selected based on the cell count of the battery being connected, below is a cell count to current table as reference for max current discharge rate. 2s - (7.4v / 8.4v) 3.0 Amps Max 3s - (11.1v / 12.6v) 4.4 Amps Max 4s - (14.8v /16.8v) 5.8 Amps Max 5s - ( 18.5v / 21.0v) 7.2 Amps Max 6s - ( 22.2v / 25.2v) 8.6 Amps Max 7s - ( 25.9v / 29.4v) 10.0 Amps Max Also included is an accessory port that allows the connection of an optional (purchased separately) audible alert that when connected, will sound a buzzer once the discharge cycle has completed. Battery management will never be as easy with the Universal Lipo Discharger Pro!!! |
