VIFLY 2pcs StoreSafe Smart LiPo Battery Discharger to Storage Voltage with Heatsink for 2S-6S RC FPV Drone Battery (2pcs) (XT60)

Works great. Not a great amount of power disapation but enough. Stops where it should. I have forgotten about them and came back in a couple of day and the batteries were both still at the correct storage voltage. A lot easier than doing this on my charger.

Works well

This is one of the most amazing products I've found in a long time. It does exactly what they say it will. It helps your batteries sooo much & saves there ability to work for a long time to come. I plain to buy more soon. I only wish they had other options for this exact battery saver. I mean different plug types, they have them for the XT-60 & XT-30 plug types. Just not for any other battery plug types (that ive been able to find so far) If someone reads this & know of other ones of this brand that can be used on other plugs please fell free to find a way to get ahold of me or leave comment on mine just any way you can think of lol. I think its well worth the price easily. The description of the product is right on. And anyone can use this without any problems, all you do is plug-in & that's it. But be sure to read instructions due to the amount if battery power you need to have to put it on. Not suree if that's the greatest words to use but shows that you need to read instructions to be sure your doing what is asked. Great product!

Yep. The StoreSafe is safe, and very clever, but too slow. I figured I'd risk it and buy it to at least give it a test. I am really impressed with everything, except the fact that this is not a practical way to discharge my fully charged 4S FPV Drone batteries. To bring a 1300mah 4S1P down to 3.8V per cell, it would take 8 hours or more. The good news are that the heatsink does not get hot enough that it could burn something that it is touching (wood/plastic/cloth); and it is smart enough to know what size battery it is discharging and when to stop discharging. The logic programmed into the little board is excellent, the LED indicators are very bright, and the whole thing is strong and looks like it could take a beating. It is extremely compact so it's easy to leave it attached to a Lipo while in a lipo bag, etc. I will probably use these little gadgets to further discharge packs that are close to 3.8V per cell only as I do not want to wait half a day to discharge my full packs. For that I have a proper charging/discharging setup. One last thing to note: a StoreSafe does NOT balance the cells in your Lipo. In my tests with healthy lipos, it was very good at keeping cell voltages even all the way down to Storage Voltage. Your results will depend on the individual health of each cell and how far apart their voltage is when you connect the StoreSafe device. Overall it is a great value and a clever execution for somebody that understands its limitation (speed).

Very cool easy to use peace of mind protection

Works as advertised. Can take a long time for larger batteries. Simple solution... buy a splitter so you can hook up 2 dischargers to 1 battery... or double split to hook up 4 dischargers. If one fails you still have the others working & they are affordable to replace.

Good idear but painfully slow to drain the battery

Works great

Excelente, me asusté porque fue entregado a un vecino, pero todo excelente

Takes days to discharge a battery ?? maybe my expectations were too high
