Hi great review! Landed on the video for the charger and stayed hooked till the end just to watch those amazing stunt flying. Maybe you could help with a couple of queries My current need is to charge 2 batteries at the same time (2S 4400mah maximum at a maximum of 3C). 1- At home what power supply would you recommend? 2- In the field (without mains supply) what's the best way to charge these batteries say about 4 times? Would be great to have your take on this.

Hi Vitor, for 2s packs you can get by just fine with a 12v power supply. I use server power supplies like these: www.ebay.com/sch/i.html?_from=R40&_nkw=HP+DPS1200-FB&_sacat=0&rt=nc&LH_ItemCondition=3000%7C2500 They typically cost around $50USD to as much as $100USD. I then trick them into turning on and outputting 12v. This mod is widely done and easy to do if only going 12v. To do 24v it's a little more work but not that bad. You can also get breakout boards that do the mod and give you terminal outputs. If you want a ready to go solution check these out: www.buddyrc.com/collections/power-supply/products/ep-buddy-900w-75a-12v-server-power-supply?variant=30274505506902. For a in the field solution I'd just charge off a 12v deep cycle battery or a vehicle battery. I hope this helps!

Just picked up a new P20 charger. I am new to ISDT, but I’ve got a PowerLab 8 and a couple of classic 4-button iChargers. Do you find that the "constant voltage" termination stage at the end of a LiPo charge seems too short? The charger stops charging not long after reaching 4.20 V, as if the CV stage is programmed to not last long enough (or rather, the termination current is set too high). The result is that the full expected capacity isn't being put back into the lipo, and as soon as I pull it off the charger it falls down to a voltage of 4.14-4.15 V. The exact same lipo is at 4.19 V resting after coming off my iChargers or PowerLab chargers. On both of those you can manually choose the CV termination current, be it C/5, C/10, or C/20.

Hi Josh. Thanks for the great review. I might have missed you covering this part, but I'm trying to find out if this is able to charge a 24v battery bank, off of a 12v power supply? Drawing high amps from the 12v is not an issue for me, I have a 12v 100A power supply. I just want to make sure this can charge my new 6s packs, without having to get a 24v power supply. Basically, do you know if it is okay with "bucking" the voltage up from 12v to 24v? Thanks very much for your help and expertise. Cheers and keep up the good work, Steve.

@@stubanshuberi8793 I had a 4010 for a little while then I downsized to the 308 duo and I've been using it for years. The P20 would be sufficient for what you're telling me but here is some theoretical math that may have you getting a P30. To charge 1 6s 5k at 1c(5a) you need 126w, to charge it at 2c(10a) you need 252w. Both of which the P20 is capable of doing whilst still having some overhead. However, if you ever wanted to charge 2 6s 5k packs in parallel, that is where the P20 will fall short and here's why. To charge 2 6s 5k packs at 1c(10a) you still only need 252w but if you go now to 2c(20a) you need 504w and while the P20 is capable of 500w max from a single port you can't do that from both because the charger is limited to 800w total output. In the video I did this test and when I did it as a "dual task" it limits the output to 400w per port. Now lets talk about the P30, taking the same 2 6s 5k packs in parallel from the last example, the P30 will limit out around 29.7 amps. Taking into account that the TOTAL output of the P30 is 1500w with a max of 1000w from the ports although not at the same time, I would guess that the charger will divide that power equally between the ports(750w for each) if you are doing a "dual task" charge. I would probably go with the P30 as it does a lot you more room to grow if you ever went up to 7s or 8s packs. Also, right now I can't find P20 chargers but the P30s are still available on Amazon. I hope this helps!

Josh, GREAT in-depth video. I am getting back into RC after about a decade break. lol. Well, a lot has changed. I am going to mostly run 10th or 8th scale trucks/buggies out on our property. I am in the market to purchase a charger and based on this review, it looks like I am torn between the P20 and the P30. Because of the extra power you get from DC, I have purchased a 400W 24v PS (www.readymaderc.com/products/details/rmrc-400w-24v-power-supply-xt60). I can return it or buy another one if you think it will not work for what I am looking to do. My goals are as follows: I will be mostly running 2s and 3s 5200mAh batteries. I love the dual ports and the fact that both of the P20 and P30 are capable of syncro parallel charging the choice for me is hard. I also have purchased a balance board to speed up the charging time. I plan to have about 6 packs total. Will the PS I purchased provide enough power to parallel charge my packs on one port (matched type packs) and charge another on the other port, or would I have to always use the syncro parallel charging feature? Would a higher Watt rated PS be better to feed either the P20 or P30 charger for my needs? Thank you again...off to watch your review on the P30! I guess the biggest delimna I have is if the charger can NOT provide enough power to parallel charge (3) 5200mAh batters to get at least 1C, would it be better to charge at higher rate on 2 individual ports. Lots of questions....
@JoshMoenheli3 жыл бұрын
I'll do my best to answer your questions. For your first question of if your power supply is large enough, for the batteries that you listed and what you want to achieve, your power supply will do it but it is running at about 80% depending on the efficiency of the supply. If it were me, I'd be looking into a 700-1000w server power supply like the HP 750w or an HP DPS1200. These are cheap and easily converted to run in series. Now I'll give you the numbers. A 2s pack is 8.4v and a 3s pack is 12.6v fully charged. With that in mind, here we go. First let's start with the packs individually, to charge a 2s 5200mAh pack at 1c you'll need about 44w of power. For the 3s 5200mAh pack you'll need around 66w of power. To charge 3 of the 2s packs in parallel you'll need roughly 131w and to charge 3 of the 3s packs you'll need about 197w. So running both channels with 3 packs each at 1c your power supply needs to put out 300-375w without fail. Now, here is why I suggest upgrading your power supply. If you wanted to charge any of your packs at 2c which is totally safe and doesn't harm the batteries, your 2s now needs 88w and the 3s needs 131w. Right there you're looking at 220w. To take this a step further if you wanted to charge 2c in parallel, 3 packs per port the 2s packs need a total of 262w and the 3s packs need 393w for a total of 655w. Now to answer the question of P20 or P30. If you wanted to charge 3 5200mAh packs at 2c in parallel which would be at 31.2a, neither charger will allow for it because of the 20 and 30 amp limits, however the P30 would be a better fit for what you wanted to do. With the higher output wattage the P30 will also give you more room to grow if you decided to get larger packs or higher cell count. ***Disclaimer time, all the above math is theoretical if we were in a perfect world.*** I hope this helps!

@JoshMoenheli3 жыл бұрын
Good question as they are very different chargers. The Q8 Max is a single port 1000w monster and the P20 is a dual port 800w charger. If you're looking at charging a lot of high capacity 6s batteries in parallel then the Q8 Max would be the one to look at. I for one am not a fan of parallel charging so I opt for multiple charging ports and charge packs individually thus eliminating the potential of a batteries failing prematurely. If you're looking to charge multiple packs of different cell counts then the P20 would be a better option because it has dual ports. You can still parallel charge on each of the P20's ports but you are a little more limited by the lower output wattage. I was able to top out the P20 with two 6s 5000mAh packs per channel. I set the current to 20a on both channels and it topped out around 17.5a because the charger ran out of available wattage. To put that in comparison, with the Q8 Max I could theoretically charge four 6s packs at an amperage of 30a which is about 1.5c and be using about 750w. If we up the cell count to 7s, you'll be around 882w. More wattage ultimately means more horsepower. All of this also relies on the input power source. In order to get any of the charge rates I'm talking about the charger will need a 24vdc power supply that outputs 200+ watts over the charger rating. I'm not too sure what packs you want to charge or how fast but I hope this helps. If you tell me what you're charging and how fast you want to go I could help drill down the determining factors.

@@mohammedal-jifry5811 No worries on asking questions. The more educated you can be on charging the more likely you are to no over-buy on a charger. I see this happen so much, someone decides to buy a 2000+ watt charger to charge the 3-4s drone racer batteries and they could've saved some money on the charger to put to more batteries or another bird. On the power supplies, I've only ever modded and used the 1200w supplies so I am not too sure if the 750w supplies would mod the same way so for that reason alone I would go for the 1200w. By doing so you will also put yourself in a little better position should you decide to add another charger to your kit. The "Max" input amperage of the P20 is really not a number to be that concerned about. The power supplies will only output what the charger is asking for. The fact that the charger only has a max input of 35a just means you can run of them off that power supply. Just remember to get the max output the charger is capable of you'll need 2 power supplies running in series to get yourself 25ish volts. I can't really answer the question of is 200w enough for 4s without knowing the pack capacities. However, you said earlier that you are charging 4ah packs so I will use that for my example. A fully charged Lipo cell is 4.2v per cell x 4 cells =16.8v for a fully charged 4s pack. If you want to charge this pack at 1c then you have a 4a charge rate, so we take 4a x 16.8v = 67.2watts and at 2c; 8a x 16.8v = 134 watts. Let's take this a step further and talk about the 6s 4ah packs. A fully charged 6s pack is 25.2v so if you want to charge a 4ah, 6s pack at 1c; 4 x 25.2v = 101watts and at 2c; 8a x 25.2v = 202watts. Take into account that this math is based on fully charged packs and the wattage needed will vary a little depending on the state of charge of the packs. But in reality if you are charging 4ah packs at 1-2c per port your looking at 200-400ish watts. So yes a 500w supply would probably cover you if this is what you are looking to do.
