    RC car batteries - LiPo v Li ion, chargers

    If a charger is labeled as "LiPo Balance Charger", it can also charge and balance LiIo cells. You can even use the LiPo Balance program directly for this if you want to fully charge the LiIo cells. If you use the LiIo Balance program instead, the end-of-charge voltage is only set to 4.10V/cell...

    Efficient way to discharge Li-ion to specific voltage?

    Sure, you can store both settings in separate memories. With the faster discharging method, setting the specified storage voltage can become more complicated if the lowest adjustable value of 3.65V is not sufficient. Then you would have to use the discharging program instead of the storage...

    Efficient way to discharge Li-ion to specific voltage?

    I advised you to the MC3000. Now I won't leave you alone with the settings either. If you want to hit the target voltage exactly even after switching off the discharge current, you must also set a low termination current for the discharge, named: Discharge Reduce. Quasi CC/CV when discharging...

    Yes, you can freely set the end-of-charge voltage in a range from 3.65V to 4.40V (including storage and LiIo4.35). This freedom of adjustment is what I appreciate so much about the MC3000. You can find the setting ranges in the operating instructions under: "BATTERY VOLTAGES" (page 11).

    But it can only differentiate between these because it doesn't have to provide a contact for LiIo sizes such as 18650. Most universal four bay chargers that can charge both LiIo and NiMh have been found not to work well with NiMh. So far I've been happy with the MC3000 here too.

    In the case of heavily aged NiMh batteries with increased internal resistance, the end-of-charge detection with the Deltapeak method is much more difficult due to the principle (triggering by heating). You can still be satisfied if your simple chargers can handle it well. In contrast to you, I...

    Efficient way to discharge Li-ion to specific voltage?

    Anything where you are dissatisfied with your charger. If you're happy with yours, you don't need it.

    Because (as already mentioned) I mostly use the cheap chargers to charge NiMh batteries, I only use the MC3000 for NiMh if I want to see the charged capacity, for example. For AAA I set: Capacity: 1100mAh; Current: 0.5A; Volts: 1.65V; DeltaPeak: 4mV; Temp: 38 degrees; Time: 135 mins For AA I...

    Efficient way to discharge Li-ion to specific voltage?

    SkyRC MC3000. But you should also know here that the battery shaft length is too short for the newer 21700 cells. https://budgetlightforum.com/node/43699

    SkyRC — IFA 2014 — MC3000 charger-analyzer

    I stopped getting upset about such terms, which only serve marketing purposes, a long time ago. Aged batteries with increased internal resistance are usually still charged reliably to a certain extent by my cheap chargers. That's why I haven't dealt with this topic on the MC3000 yet...

    Higher graphics resolution could be used, for example, to make operation easier by showing more lines or two columns on the display. You would then not have to click through 17 lines to activate a change. The dummy mode is bad, you're right. The storable profiles are a relief. Standard tasks...

    SkyRC — IFA 2014 — MC3000 charger-analyzer

    It's not as bad as you make it out to be. After all, the manufacturer has responded to many user requests. I haven't found a four slot charger that allows a similar free access to the charge/discharge parameters. Current and voltage values can be calibrated. That's rare in this category. A...

    Probably purely for marketing reasons, like this: "We have the right charger for your valuable Eneloop batteries."

    There is no difference between NiMh and Eneloop charging programs. You can charge the Eneloop with any NiMh charger.

    Not an alert, but a notice

    At first I would blame the charger or an incorrect setting for overcharging a NiMh battery. Did you charge with 0.5 or 1.0A? As NiMh batteries age, the chargers have a harder time recognizing the delta peak correctly. At the moment I only have 2 Fujitsu AA batteries in constant use. So far...

    It could have been due to a bad contact on the minus side? With the small diameter of the AAA batteries, it can easily happen that the negative pole of the battery does not make proper contact with the sliding contact of the charger...

    Should I bin it.

    Yes - it is really difficult to give the right advice if it is only slightly damaged. First I wanted to write that in such a case I would also observe the battery with the slight dent more intensively, but then probably continue to use it for myself. The pressure point is really only small...

    Should I bin it.

    Something like that is always difficult to judge from the outside despite the relatively good pictures. For safety reasons, I would dispose of the one with the dent. I would mark the one without visible damage, but continue to use it.
