220V Lithium Battery Cell Balanced Charger with 4 Pair of Wires 2.70-4.85V/1-40A Adjustable for New Energy Vehicles

Description:
- This product is not an ordinary charger, with an adjustable output voltage of 2.70-4.85V. It is mainly used to supplement the voltage of a single string of battery cells before assembling large capacity lithium battery packs, or to maintain the use of lithium batteries in daily life.
- High precision display. The voltage display is accurate to two decimal places after the decimal point. The voltage error is about 0.02V. The current error is about 0.2A. Intelligent temperature control fan, the higher the charging current, the higher the fan speed. Effectively extend the service life of the fan.
- Without reverse connection protection.
- 4 Pair of wires with positive and negative output clips. Simultaneously charge four battery cells in parallel (note: parallel!). When all four cells are charged simultaneously, each cell can provide a charging current of about 6-9A (the current gradually decreases as the cell voltage increases during later charging). It is strictly prohibited to directly apply the clip to batteries with a voltage higher than 6V, as it may damage the reverse module.
- It can only be used for charging, and there is no discharge function.

Instructions:
- If you only charge one battery cell (or a string of batteries), you can take any set of red and black wires and clip them together. If the capacity of the battery cell is large, four sets of wires can be clamped onto one battery cell at the same time to increase the current for charging (when clamped onto one battery cell at the same time, the current may not necessarily increase by several times, and the specific maximum total current size depends on the internal resistance of the charging battery cell and the battery's own capacity, which may be around 15-40A).
- For the version that the current cannot be adjusted, if only one battery cell is charged. You can choose the number of battery cell clamps to roughly adjust the current value.
- Full self stop, the indicator light on the power supply is the power indicator and does not change color. The power supply usually heats up during charging. The power supply does not heat up when fully charged. Of course, you can also use a digital meter to measure the voltage of the battery cell. If the lithium iron battery is 3.65V or the ternary polymer battery is 4.2V, it is fully charged (Warning! The adjustable power supply means adjusting the no-load voltage to a certain level and charge it to the highest level, and the lithium iron phosphate battery can be adjusted to 3.65V or the ternary polymer lithium battery can be adjusted to 4.2V. Do not adjust it too high.). After being fully charged, the power will not be cut off, and the battery cell voltage will only be maintained. It won't overcharge. (No load refers to the charger being plugged into 220V and the output not connected to the battery)
- The button above is for adjusting the current, a single turn potentiometer. The one below is for voltage adjustment. The one for voltage adjustment is a precision multi turn potentiometer, which may not change much after one or two turns. It can be turned up to 10 times (without a stopper, you can hear a small clicking sound inside the potentiometer when you turn it to the end), usually clockwise to increase and counterclockwise to decrease.

Precaution:
- Please note that it cannot be directly used to balance several strings of lithium battery packs that are not disassembled at the same time. Because the entire set of battery cells has already been connected in series. Further parallel connection is equivalent to a short circuit. If you want to charge them in a balanced manner, only charge one string without dismantling it, and then replace it with the other string after it is fully charged.
- The general usage method is to clamp the four battery cells to be assembled, regardless of the voltage, on balanced charging (which is equivalent to several cells being connected in parallel). Fill it all at once and then assemble it in series.
- The power supply voltage regulation is a multi turn precision potentiometer (when adjusting the voltage, it should be unloaded, that is, do not clamp the battery), and the current regulation is a single turn potentiometer (clockwise adjustment increases).
- The default is set to 3.65V (voltage for charging lithium iron phosphate), when you need to charge a ternary polymer battery, please adjust it to 4.2V before use. When charging lithium iron phosphate again, remember to adjust it back to 3.65V.
- Lithium batteries are usually charged with a current of 0.3C. You can adjust the current knob according to the battery capacity, and then increase the current knob according to the battery capacity. (C refers to the total capacity of the battery, for example, a 100AH lithium battery, 100 * 0.3C=30A)

Note:
- Check the current display directly to see if it is fully charged. If the current displays 0 or close to 0, it means it is fully charged.
- Please keep away from flammable and explosive materials when using And there must be someone on duty in the place. The power supply has a metal casing and is fixed with screws for wiring. According to electrical standards, the casing is securely grounded. This product is only suitable for professionals with professional knowledge. Those who understand electronics, batteries, and safe electricity use can purchase it.
- To prevent personal accidents, fire accidents, electric shock injuries, social damage, etc. caused by malfunctions and incorrect work, please pay full attention and take safety precautions. The product has a certain degree of danger. Please use it carefully while ensuring safety and avoid crowds as much as possible. Your purchase behavior represents that you are aware of the above situation and voluntarily assume corresponding responsibilities and risks.
