__________________________________________________ __________________________________________________ _____________ External Discharge Function External discharge function makes use of external high-power load resistance to discharge the battery accurately quickly. When used, the battery to be discharged needs to be connected to the input port and output the connection resistance load. The recommended load resistance is between 1.5 and 2.5Ω. Other resistance values can be used normally, but may not run at full power. When external discharge is running, the load is very hot. Please pay attention to safety and avoid accidents or personal injury. -------------------------------------------------------------------------------------------------------------------------------- I didn't tried it yet ...

Discharge and balance current
The charger manual says that it has a collective balance current of 1.6amps per port.
And a discharge current of up to 3amps. Why can't I get this charger to balance or discharge at more that 300mA? Even when I set the Discharge current at any value under 3amps. It only ever discharges at 0.2 - 0.3 amps. I brought this charger because it is supposed to have a high balance current ability. But its not showing it. Is there some setting that is hidden? to allow this to work as the specs say? |

If you are talking about the D6 Duo Pro and discharging a 1s, 2s or 3s battery the display is all wrong for current. To get the correct current go to the dual page and find the watts out and divide that by the voltage that will give you the current.
Hobbymate says they will fix this shortly with a firmware update. |

Hasn't anyone here tested the balance or discharge function? It will only discharge at 0.3amp That's about all? And its does this on all cell counts, from one to six cells. And I have tested it with DC clamp meter. The current reading on its display, is the same as it is discharging..... Only 0.3amps, according to the DC clamp meter. Its not the only thing that's wrong. The voltage vs capacity read out is also out by up to 20%, from a standard Lipo table, in the mid-range balance region. As for the 1.0.29 firmware upgrade spoken of here as well. Isn't it supposed to turn the fan off in standby? Mine just keeps going the same as it did before the upgrade. It doesn't matter how long it sits idle in standby.... the fan keeps running. It does charge at what it is rated at. But that's about all it does that the specs say. |

Internal resistance
What I found is reading IR ...some Bat does some does not even after 2-5 minutes in Charge mode. On the some videos readout is fast, in my case I am not sure.

If yes and if you using Hobbymate V1.0.29 firmware than fan keeps running. But if you disable wireless charging, than fan will turn off. Also with original HOTA firmware V1.0.27 there's no fan running even if wireless charging is enabled (only difference between Hobbymate .29 and Hota .27 FW) |

external discharge
You just need to connect your Lipo to input DC port of charger (without balance leads connected) and connect external load to output CH1 (Lipo) socket.
External discharge works perfect in my case using 3 ohm 400W load (2 x parallel / 2 x serial 100W 3ohm resistors array on aluminum heat-sink + fan) I can discharge 4S lipo with around 5A max current. For higher discharge current you can use even lower resistance (min 1.5ohm) |

I think it is working OK. |

Can you guys also tell me if your chargers can discharge or balance at more than 0.3amps? |

Max discharge currentQuote:
But there's also 0.3A max on mine with 4S (I think it can handle litlebit more if only one channel is used) so there must be something wrong in specification or firmware Anyway for higher current you need to use external discharge |
