How big should a 3 7 3350mA3 string 5 and lithium battery charger be?

The highest charging voltage of lithium battery, 3 strings is. Lithium batteries do not have the same charging current as lead-acid batteries.

The requirements are so high, it can be charged quickly (that is, it allows a relatively large current to charge), or it can be charged slowly, so the choice of charger is relatively large. The main thing is that the maximum voltage can not be exceeded, and the current is taken from the capacity of the battery.

20% of 50%, 3350mAh5 and 16750mAh, it's 20% 50% is. Too much current charging requires temperature detection and protection, so as not to cause excessive temperature**, if there is no temperature detection and protection, it is recommended to choose a charger of 3 5A.

3 strings, 5 for 16750mAh (17ah), the rated voltage of the charger is volt (12V), and the charging current is (more appropriate.

For charger, charging current, charging time 5 hours, full voltage.

Lithium battery, fully charged battery, 3 strings of 5 and composed, fully charged.

Charging current rate current, slow charging, charger input power 50W, suitable.

If it is charged quickly, it can multiply the current, and the charging time is more than 2 hours to fully charge. The input power of the charger is 120W.

Summary. Hello dear, 4 lithium iron batteries are charged in series with a volt charger Oh, the nominal lithium iron phosphate battery, full of voltage, 4 in series 4. The minimum discharge voltage is 4.

The charging current is 1350mAh charging current 270mA 675mA, and the charger should be charged with constant current fast charging and constant voltage float charge until it is full. Is the device a charger or a power adapter? It seems that there is a router power adapter used, that is not the charger does not have a charging control function, the current and voltage are different, and it cannot be used for charging.

Hello, I am glad to serve you, I have received your question, and I am sorting out the answer for you, it takes time to guess the word on the bridge, and please be patient and wait for a while, and answer it for you immediately! Potato eyes.

Hello dear, 4 lithium iron batteries are charged with volts charger after bending, the nominal lithium iron phosphate battery, full of voltage, 4 in series 4. The minimum discharge voltage is 4. The charging current is 1350mAh charging current 270mA 675mA, and the charger should be charged with constant current fast charging and constant voltage float charge until it is full.

Is the device a charger or a power adapter? It seems that the core lets the power adapter of the router be used, that is not that the charger does not have a charging control function, the current is different from the electricity or stuffy voltage, and it cannot be used for charging.

Dear, I'm glad to answer for you: The output of the lithium battery charger is a few volts Answer: Do a kiss Good afternoon! <>

The output of the lithium battery charger is a 48-volt lithium battery, which was first used in pacemakers. The self-discharge rate of lithium batteries is extremely low, and the discharge voltage is gentle, so that the pacemaker implanted in the human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than volts, which is more suitable for integrated circuit power supply.

Manganese dioxide batteries are widely used in calculators, digital cameras, and watches. After the lithium battery cell is overcharged to a voltage higher than that, it will begin to produce ***. The higher the overcharge voltage, the higher the danger.

When the voltage of the lithium cell is higher, less than half of the lithium atoms remain in the cathode material, and the storage compartment will often collapse, causing the battery to produce permanent capacity loss. If the charge continues, the storage grid of the negative electrode is filled with lithium atoms, and the subsequent lithium metal will accumulate on the surface of the negative electrode material. Thank you for your patience.

The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best! Peace and joy!

It is necessary to use a charger with the highest limiting voltage, due to the capacity and performance of lithium batteries are only in a certain difference, it is best to use 4 batteries in series with a suitable battery equalizer. If your charger meets this voltage, it can be used, as for the charging current is not too big, just the length of charging time.

4 cells, 5000mA lithium iron phosphate battery series output voltage shall not exceed 15V (the maximum safe charging voltage of lithium iron battery is not greater, that is, the charger of 4 strings is suitable for charging.)

In theory it is possible to have a lithium battery with a protective plate. But it is better to use a volt charger for long-term use. Iron and lithium are to be volatile. Both of the above should be equipped with a balanced flush double insurance... Hope to adopt.

13 strings of lithium batteries cannot be charged with a 58,4V charger.

Reason: At present, there are usually two kinds of lithium rechargeable batteries, one is a 3 2V lithium battery, the charging limit voltage is 3 6V, and the full charge voltage of 13 strings is 13 3 6 46 8V; The other is a 3 7V lithium battery, the charging limit voltage is 4 2V, and the full charge voltage of 13 strings is 13 4 2 54 6V.

Lithium batteries have very strict requirements for charging voltage, and overcharging is not allowed, otherwise it is easy to wear short service life and is prone to danger.

The charging voltage of any model of 13-string lithium battery is too high and therefore cannot be used.

Please choose the appropriate charger for the specific model of the lithium battery.

50 and? That's 90ah capacity, then you're quite big, the charger with ordinary single-digit current is charged very slowly, you can buy a high-current constant current and constant voltage step-down module, I bought a module with a maximum power of 300W, and a maximum current of 20A is 18 pieces of free shipping, and then find a 24V switching power supply of at least 300W or so, and then you connect the switching power supply and adjust the output voltage of 13V (don't use it, so that the later charge is very slow, the current is reduced too much, and the current drops small in the later stage if it is 13V, Because you are 3 strings of batteries must be connected to the protection board, so that the charge is full) by the way, you have to buy at least 20A current or larger, 3 strings of 20A protection board is only a few dollars, I have several You see if there is a larger current, your 90Ah capacity battery, at least 40A charging current Consider that your switching power supply power is not necessarily too large, if the power supply is only two or three hundred watts, you can buy a 20A current protection board, The charging current is adjusted to about 15A, and it can be filled in 7 hours, if the switching power supply is also bought large, and the module is also large, then you can adjust the current to 40, 50, so that it can be full in the early two hours It depends on how long you need it, if you don't care about the time, buy a ready-made charger is basically twenty or thirty, but this thing is too slow, you have to have a day and a night.

The module can generally receive a voltage input below 40V, and the output current depends on how big you buy, I am a relatively good module to buy, and it is not easy to find more than this parameter, if you are too slow, you can buy two in parallel As long as the power supply is enough, the two can output 40A current, and it is only more than 30 yuan. According to the current of 30A, 13 * 30 = 390W, then you have to buy a 24V25A, 600W switching power supply, so that it is almost the same, the conversion rate of the module is about 85%, 600W You can't output the full power, right, so that the pressure is not too big. Or buy a 36V power supply, anyway, the output power is large.

Xianyu went up to take a look, the new switching power supply is very expensive, and the old one is very cheap.
