Lithium Polymer Battery Charging Tips

4 tips on how to charge your lithium ion battery properly.

Lithium polymer battery charging tips.

If you lose your charger or need to borrow one check that it s made for lithium batteries. Lithium ion and lithium polymer batteries should be kept at charge levels between 30 and 70 at all times. The original charger will be of no use. Lithium or not the care and maintenance must be the same.

When a lithium battery is fully charged the charger will adjust to reduce the flow of the current. Knowing these simple tips for properly charging your lithium ion batteries will take a long way. Therefore it is equally important to care for your lithium ion batteries the same way you care for a regular car 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.

Be absolutely sure that the lithium polymer charger settings are correct for the battery pack being charged bothvoltage and current settings. Do not charge batteries near flammable items or liquids. Additionally the charger might open up the battery to release some of the power so the battery isn t over charged. Importantly operating at a low voltage is good for a battery s lifespan increasing the number of.

Batteries should never be left unattended while charging. Exceptions to this can be. 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. Partial charging is just fine for lithium ion batteries and even has some positive benefits.

Full charge discharge cycles should be avoided if possible. Low temperature large current 24v emergency starting power supply battery specification. Whenever possible use the battery charger that came with your battery. 25 2v28ah lithium battery 27v300f supercapacitor pack charging temperature 40 50 discharging temperature.
