CCC is the English abbreviation of “China Compulsory Product Certification System”, and is the unified mark used by the country for compulsory product certification. The CCC-certified power adapter meets the requirements of national mandatory standards in terms of electrical safety and electromagnetic compatibility.
If consumers use a charger that has not been certified by 3C to charge their mobile phones while answering the phone, they may get an electric shock and endanger their personal safety. In addition, if you use a charger that has not been 3C safety certified to charge your mobile phone, a little carelessness may damage the mobile phone. Then, leakage, short circuit and fire may occur during charging, which may cause personal injury and fire.
It is important to choose the right charger for your battery. The right charger will make your battery function as safely and efficiently as possible. There are a few different factors that go into choosing a charger, each of which is detailed below.
This one is critical. Most lithium battery chargers are designed for either lithium-ion batteries or lithium iron phosphate (LiFePO4) batteries. The difference is the charge voltage. You have to choose the right type of charger to ensure that you will have the correct charge voltage.
That leads us to our next issue: charging voltage. If you’re using a VRUZEND battery building kit then you’re almost certainly using li-ion cells that should be charged to 4.2 V per cell. That means you’ll need a charger that has an output voltage that is 4.2 V x the number of cells in series in your battery.
For a 10s battery with 10 cells in series, that means you need a charger that outputs 4.2 V x 10 cells = 42.0 V.
For a 13s battery with 13 cells in series, you’d need a 54.6 V charger.
For a 14s battery with 14 cells in series, you’d need a 58.8 V charger.
And so on.
You can actually increase the life of your battery by slightly undercharging it, but we’ll talk about that further down in this article.
You also want to consider charging current. Most lithium ion cells should not be charged above 1 C, though most prefer to stay below 0.5 C. The “C” rating is simply the capacity of the battery. So for a 3.5 Ah cell, 1 C would be 3.5 A. For a 10 Ah battery pack, 0.5 C would be 5 A. Got it?
