Three strings of lithium batteries cannot be charged at 12.6 volts

Introduction Three strings of lithium batteries cannot be charged on one 12.6 volt lithium battery. Three strings of 12-volt lithium batteries cannot be charged. Batteries connected in series must have the same capacity and voltage, and the 12.6V charger is usually to

Three strings of lithium batteries cannot be charged at 12.6 volts

Three strings of 12 volt lithium batteries cannot be fully charged. The capacity and voltage of the batteries connected in series should be the same, and the 12.6V charger is too weak. Generally, the voltage of three batteries connected in series is. 12.5V, and a 13V charger should be used to charge it. However, as long as the charger is a 12V lithium battery charger, the maximum voltage is generally 13V. The protection board should be 12V. You can also remove the protection board and charge it. If it can be fully charged, it means the protection board is broken. If you use 12V lead acid battery charger, it can be fully charged, but the charger shows it is not fully charged because the full charge voltage of lead acid battery charger should be 13.5V or 14 V, while lithium batteries can only be charged at 12.5V.

At present, most batteries with floating charge function are mainly lead-acid batteries and nickel-metal hydride/nickel-chromium batteries; there are still chargers for lithium-ion batteries and lithium iron phosphate batteries; China. Still using the float charge function, many overseas customers do not require the use of battery chargers with float charge function, but require the battery charger to be OFF. Once charging is complete, the battery charger should have a cut-off. charging function. ;

The advantages of long-term float charging: It can replenish the battery power lost due to the internal resistance of the battery, so that the battery can be at full capacity.

p>

The disadvantages of long-term float charging: Long-term charging of the battery. Power replenishmentwill expose the battery to electrochemical reactions for a long time, which can easily make the electrochemical reactions of lithium-ion batteries unstable. resulting in swelling, battery burn, etc. ;

Therefore, the battery charger used in the future will be. Especially because of the characteristics of lithium-ion batteries, more and more companies that focus on quality requirements will consider battery chargers that do not use long-term floating charging when designing products. The following two 3-string lithium battery chargers are the charger with float charge function and the battery charger without float charge function.

P2012-L3? 3 string lithium battery charger with float charge function

G60-12L3? 3 string lithium battery charger without float charge function

These two lithium battery chargershave the same point: they both charge 3-string lithium-ion batteries, the difference: one. has a large charging current, and the other has a smaller charging current. The one with high current does not have floating charging function, and the one with low current has floating charging function. This also shows that charging with high current is recommended. . A battery charger with charging function. If the current is low, you can choose a battery charger with floating charging function.
