Good morning,
I am having some issue with a charger since I am not able (differently from the others) to select the battery type, the current and all the settings I should be able to have according to technical specifications. Basically, I can only choose the Storage or Charge mode, and 4S 14.8 V. Do you know if I can reset the charger somehow?
Thanks in advance.
Hi @RiccaSuso -
Welcome to the forums!
By default, the H6 charger comes configured to only charge 4S (or 6S with newer firmware.) This is to avoid all the complicated settings leading to user error and risk of fire!
If you’d like the advanced functionality, you can unlock the charger.
Hi Tony,
thank you very much for your answer, very much appreciated. Do the batteries need to be charge only to 3.8 V per cell then?
This will limit the storage capacity of the battery , isn’t it?
Another question: is it possible that these settings are wrong?
I have the possibility to have advanced possibility to set up charging of them for 2 chargers of the same type.
-Charging parameters: LiPO
-Charging mode: Balance
-Cell count: 4(4S)
-Ending Voltage: 16.8 V (Target voltage per cell: 4.2 V)
-Charge Rate: 10 A
Hi @RiccaSuso -
The H6 charger is configured by default to charge 4s or 6S to 4.2V per cell - are you experiencing something different? Can you share pictures of your unit’s configuration if so?
I checked and even if charger sets 14.8, any cell is charged up to 4.2 V.
Therefore, I clarified my doubts.
Thanks.
By the way, we are experiencing a loss of cells (1 per battery) on our equipment.
Do you think that it could be due to the fact that the batteries are also charged up to 4.2V per cell even if not used in the short term (preventive action for the operations)? And what would you do if one battery (LiPO) is not recognized as LiPO anymore (abnormal signal)?
Hi @RiccaSuso -14.8 V is the nominal voltage for a 4S pack, not the max! You use this voltage when calculating capacity, multiplying it by the amp-hours of the pack to get watt-hours.
Charging up a battery to full and letting it sit is not likely to damage an overall sell - it can just negatively impact the overall capacity of the pack to a small degree.
If one cell is reading a much lower voltage, either the balance connector is damaged/corroded/not making a good connection to the charger, or the cell is failing. I’d recommend replacing the balance connector, a single wire at a time to avoid the risk of shorts, and seeing if the charger can recover the low cell after that. If the overall voltage is too low, the battery may not be recoverable / usable anymore, and should be properly disposed of…
