Coolice Charge Cases ToolkitRC M8D Review

Hello.
Here is my first ever RC LiPo charger review of the new ToolkitRC M8D, I hope some of you find it useful

If the input voltage is only 24v, how much will the charge rate be reduced? Still get 500 watt/20amp on a 6s per channel?

[@CooliceChargeCases]

Hey Buddy. I can't see any details yet about current reduction below a specific voltage as we see on other chargers, but can assume there will be less power available from say a 12 volt DC source Vs a 24 volt one. Effectively you'd be governed by the overall chargers limits of 800 watts per channel and 60 amps overall current draw for the charger itself. Using a calculator as I still cannot work this out in my head, 800 watts with a 24 volts input equals 33.3 amps per channel, but then 2 x 33 amps is above the overall limit. So then you'd be back to 30 amps max per channel (60 amps charger total) on 24 volts and then need to allow for efficiency losses. 24 volts input and 30 amps yields 720 watts of charging power Going up slightly to a 30 volts DC input increases the charging power to 900 watts at 30 amps. I think it is safe to say that you can extract the full charging capability of this charger from a 24 volts (or above) input from your DC power supply. Ian Contessa

Sir;What is your opinion on charging a 16 cell li-ion pouch pack all in series by using each side of the 9 pin JST connectors.Bringing 4 charging wires from the battery and charging both halves of the 16S pack at the same time.Also wiring each + & - terminals of the 16 cells with the JST wires.Using fast acting pico fuses on each terminal also for safety on the JST wires.

I just received the same charger. So far, I like it. But it does have a few things that could be better, such as the touch screen sensitivity. Quick question: Where did you buy your power supply from? I currently own a 24v power supply. But, like you, I want to be able to supply at least 48v to the M8D charger. I cannot seem to find any seelers online who sell a 48v power supply especially for Lipo chargers.

Hey Buddy. Great, these are nice chargers. Sadly I have returned mine as I heard of a few issues with the screen bezel on the batch one units, basically it was coming away from the plastic shell due to the wrong glue used and ToolkitRC said this in an email reply to one guy who suffered from it. There was three instances of this problem and one other where the screen went green, none of which I have heard of the fix for or replacement. One suggestion they gave was to glue it back in, not good on a brand new charger. I also sent an email direct to ToolkitRC asking if there was a way to work out if I had a batch 1 or 2 unit from the serial numbers, or if the new parts were available to fix the issue, as I never got a reply I lost confidence in the product for now and will try again in the future. So please do keep me posted on how you get on with yours, as for me building charge cases this M8D has all the features I would like to build one around, but I must have confidence in it to recommend it to my customers. The power supply I have sourced myself, it is a Huawei rectifier, but by default outputs a higher voltage than the M8D can take. However as I sell these and Eltek power supplies for use as standalone units, or built within charge cases, I have a device to communicate via Canbus and set the output voltage. So ultimately i can help you with a ready to go 48 volt power supply to run your M8D from if you'd like to go this way. If yes give me a shout on email; [e-mail] Cheers.

Interesting charger. I have sen it in aliexpress. Already using other 2 models toolkit charger, and are my favourite chargers till now. Work very well

[@CooliceChargeCases]

Hey. Yes it is, this is what appealed to me as with it being dual channel, with a touch screen and capable of higher than usual DC input voltages all making it very attractive at this price point. Good to hear your other ToolkitRC chargers are working well for you, I have been following their products, but this is my first item from them. Ian Contessa

Thanks buddy. It is a nice little charger so far, it's charged a 6s 5000mah LiPo beside me and is not storage discharging it to. Ian
