![]() ![]() So I decided to get the portable power station so that I can charge the battery at the field. While I was waiting for the Fly More package, I only have 1 battery that came with the Mini 3. Well said! I've been fast charging devices for years and people "can still hear me now." M2P/Smart Controller, Mini, Mini 2, Air2, Air2S, M3C/RC Pro and now the Mini 3 Pro/DJI RC.īack on topic: I'm currently using this 95w charger in the truck and it's been great! I have never seen a LiPo cell rated at less than 1C recharge rate, and I would wager cash that the ones in the Mini 3 Pro's battery are rated much higher, as the recharge rate would be related to the discharge rate, which if a flight lasts about 30 minutes, would make it 2C at least. For Ss & Gs, let's call it a recharge rate close to 2C. That means that a 36 watt charger would recharge the battery in between 35-50 minutes, given the heating losses and balancing inefficiencies in the battery smarts. or, with it's rated voltage, around 18 Wh. For the Mini 3 standard battery, that would be 2.5 A. Typically, the lowest recharge rate would be 1C (1 times the Ah rating of the battery or cell). The only issue is, at some point in time, the smarts in the battery will only allow so much "gozinta" - and DJI has not specified how much that max gozinta is, from what I've read, and the standard battery doesn't seem to mind my 65W charger one bit.Īll LiPos are rated by the manufacturer for maximum acceptable recharge rate. Given the tolerances on a modern LiPo cell, I wouldn't be surprised if a 5C charge rate would be totally harmless as well. If it takes at least as long or longer to charge than it does discharge, there is absolutely zero chance of harming the battery by charging it at this rate. I have never seen a LiPo cell rated at less than 1C recharge rate, and I would wager cash that the ones in the Mini 3 Pro's battery are rated much higher, as the recharge rate would be related to the discharge rate, which if a flight lasts about 30 minutes, would make it 2C at least. ![]() I charge and circle at about 20 metres until the 30% warning.All LiPos are rated by the manufacturer for maximum acceptable recharge rate. ![]() On the plus side, my mavic pro batteries are still pumping out close to their original flight time when i bought them back in 2017. The cells will be much hotter than the case when flying at full power on a hot day. Please note, it is the cell temperature that is important, not how hot the case is. Flying or recharging a hot battery (above the manufacturers max temp) will rapidly degrade the battery. The longer the battery remains at 100%, the quicker it will degrade although not as fatal as going down to 0%įlying in low temperatures only reduces the power output. You can slow the degrade to some extent by keeping the charge between 20% to 80% but you will need to go to 100% just prior to flight. That is a fact.Īlso, you can't stop your battery degrading, it started doing that the moment it was made. The faster you charge this battery chemistry, the faster the cells degrade. I'm sure it has to do something with the batteries firmware keeping them from overcharging. ![]() I have a 45W charger also and I tried that on the 2nd extended battery and it still took 1 hour and 40 minutes to charge so the intelligent batteries must only accept up to a 30W charge at a time. I have the extended batteries which take a full 1 hour and 40 minutes to charge with a 30W charger. ![]()
