Lithium Polymer Battery Charging Tips

Lithium or not the care and maintenance must be the same.

Lithium polymer battery charging tips. Lithium ion and lithium polymer batteries should be kept at charge levels between 30 and 70 at all times. Be absolutely sure that the lithium polymer charger settings are correct for the battery pack being charged bothvoltage and current settings. When the battery terminal voltage reaches the charging limit voltage of 4 2v change to constant voltage charging until the charging current is less than or equal to 1 20c stop charging leave it for 0 5h to 1h and then discharge it at 1c to the termination voltage of 2 75v. Whenever possible use the battery charger that came with your battery.

The tips of lithium polymer battery charging and discharging just as with other kinds of lithium ion cells the voltage of a lipo cell depends on its chemistry and varies from about 2 7 3 0 v discharged to about 4 20 4 35 v fully charged for cells based on lithium metal oxides such as licoo2 and around 1 8 2 0 v discharged to 3 6 3 8 v charged for those based on lithium iron phosphate lifepo4. Therefore it is equally important to care for your lithium ion batteries the same way you care for a regular car battery. The original charger will be of no use. If you lose your charger or need to borrow one check that it s made for lithium batteries.

When a lithium battery is fully charged the charger will adjust to reduce the flow of the current. Low temperature large current 24v emergency starting power supply battery specification. 25 2v28ah lithium battery 27v300f supercapacitor pack charging temperature 40 50 discharging temperature. Knowing these simple tips for properly charging your lithium ion batteries will take a long way.

Exceptions to this can be. If a lithium ion battery is discharged below 2 5 volts per cell a safety circuit built into the battery opens and the battery appears to be dead. Do not charge batteries near flammable items or liquids. Lithium polymer must be charged and stored in a fire safe container like a lipo sack.

Before we get into the charging tips let s discuss something about the science of lithium ion batteries. 4 tips on how to charge your lithium ion battery properly. Full charge discharge cycles should be avoided if possible. Additionally the charger might open up the battery to release some of the power so the battery isn t over charged.
