## Description

Product description FAQ Q: Why do I only see “Charge” and “Destroy” modes in the menu? A: Once you manually select the battery type (such as Li-ion, NiMH, LiFePO₄, etc.), you will gain access to advanced features including Discharge, Storage, Analysis, Cycle, and Activation modes. Q: Why does the charger make a slight high-pitched sound during charging or analysis? A: At higher charging or discharging currents, internal power components may produce slight operating sounds. Reducing the current setting (such as 0.6A) can help minimize heat, fan activity, and operating noise. Q: What is Destroy mode used for? A: Destroy mode safely discharges batteries before disposal. It is designed for damaged or unwanted batteries and is not intended for normal daily use. Q: Why does the charger restart or flash during charging? A: The C4EVO requires a fast-charging USB-C adapter (PD/QC) with at least 18W output. Low-power adapters may cause restarting, flashing, or unstable charging.

Review: ISDT C4 EVO Universal AA &AAA BATTERY CHARGER - I have to say the ISDT C4 EVO AA &AAA BATTERY CHARGER is amazing with my 4s lipo battery it will charge my 1s lipo for my 12th scale on-road car at the track for the price its a great investment
Review: The best charger I have ever seen! - I own so many kinds of battery chargers and this one is the best. I like Nitecore chargers, but they give you very limited control of the charging parameters. This charger will work automatically if you don't care about the settings, but I prefer to charge my batteries at 1C or slower rates and this charger let's me set it exactly how I want it. It also graphs the charging process so that you can estimate the battery's health. I love that this charger has a cooling fan because that will extend its life. This charger will also discharge batteries and refresh them. If you fast charge batteries at higher amps then I recommend getting a nice USB power source that is rated for it so that you don't overheat your low amp wall charger. I have not had any problems at all, but a while back I thought my Great Planes Triton R/C charger was broken, but it ended up being the Pyramid 12 volt power supply that I was powering it with did not produce enough amps to charge my 5,000mah battery packs at the rates that I wanted. I'm telling you this because I would hate for you to underpower this charger and then think it's broken if it pops up with an error on the screen. I highly recommend buying this charger!
