锂聚合物电池的维护与保养(2)

LIPO The cutoff is usually around 6。25 volts or 3。0 volts per cell。 Once a LiPo discharges below 3。0 volts per cell, there is less chance that you will get it to recharge again。 6。25V3。0VLIPO3。0V Do 3 cells take more time to maintain? 3? It does not take more time - it takes more care! The maintenance is the same for any LiPo batteries, but common sense is your greatest tool。 LIPO Unfortunately, people who do not take care and follow the rules set by the battery manufacturer are to blame for LiPo-related disasters due to incompetence。

LIPO Examples of improperly treated batteries include: running their motors until it’s 80 degrees centigrade, overheating batteries, overcharging with the incorrect charger settings, and over-discharging the battery。 80 Lithium Polymer Safety Tips : Lithium Polymer cells are a tremendous advance in battery technology for RC use。 However, due to the chemistry of lithium cells, there is a possibility of fire if charging is not done properly! LIPORCLIPO Care is unavoidable due to the nature of lithium itself。

- 6 - This is no different from many things we use in daily life – knives, kitchen cleaners, and automobiles, for example – which are inherently dangerous, but which can be used safely by adhering to simple rules and precautions。 – • Be absolutely sure that the Lithium Polymer charger settings are correct for the battery pack being charged – both voltage and current settings。 LIPO– • Lithium Polymer must be CHARGED and STORED in a fire-safe container like a LiPo Sack。

LIPO() • Do not charge batteries near flammable items or liquids。 • Keep a dry fire extinguisher nearby - or a large bucket of dry sand, which is a cheap and effective extinguisher。 – () • Never charge inside an automobile even when parked。 • Batteries should NEVER be left unattended while charging。 • KEEP BATTERIES AWAY from children and pets at ALL times。 。 Handling Cautions New cells may have a high initial charge, and care must always be taken to insure that the battery is not short-circuited。

• Never leave batteries on a hot day in direct sunlight, or in any other place where ambient temperature may exceed 140F/60C。 60 • Do not put the loose cells in a pocket, bag, or drawer where they could short-circuit against other items, or where the battery tabs could be pressed against each other。 - 7 - • Do not place the loose cells on any conductive surface, such as a metal-topped table。 • Take special care that metallic objects like hobby knives do not puncture the cells。

• If the electrolyte in the cells should get on your skin, thoroughly wash with soap and water。 If in the eyes, rinse thoroughly with cool water。 Immediately seek medical attention for this or for burns。 Can I still use or fix a LiPo battery if it has been damaged or mishandled? ? If a LiPo battery has been physically damaged or discharged or overcharged beyond its recommended limits and the pack is swelling, DO NOT try to fix or repair the battery。 LIPO It would be best to follow the steps below for proper disposal of the LiPo cells。

The batteries must also be cool before proceeding with disposal instructions。 LIPO To dispose of LiPo cells and packs LIPO: If any LiPo cell in the pack has been physically damaged, resulting in a swollen cell or a split or tear in a cell’s foil covering, DO NOT discharge the battery。 Proceed right to step 5 on this list。 LIPO5 If you are disposing of LiPo batteries/cells: LIPO/: 1。 Place the LiPo battery in a fireproof container or bucket of sand。 1。 2。 Connect the battery to a LiPo discharger。

Set the discharge cutoff voltage to the lowest possible value。 Set the discharge current to a C/10 value, with “C” being the capacity rating of the pack。 For example, the “1C” rating for a 1200mAh battery is 1。2A, and that battery’s C/10 current value is (1。2A - 8 - / 10) can be used, such as a power resistor or set of light bulbs as long as the discharge current doesn’t exceed the C/10 value and cause an overheating condition。 For LiPo packs rated at 7。4V and 11。

1V, connect a 150-ohm resistor with a power rating of 2 watts (commonly found at a local electronics store) to the pack’s positive and negative terminals to safely discharge。 Connecting the battery to an ESC/motor system and allowing the motor to run indefinitely until no power remains would be an alternative way to discharge the battery。 2。 C1/101200MAH1C1。2A1/10C0。12Aige 1/10C7。4V11。1V2150() / 3。 Discharge the battery until its voltage reaches 1。0V per cell or lower。 For resistive load type discharges, discharge the battery for up to 24 hours。

then open the electronic table cover wrapthe calcium chloride and electronic form in an airtight plastic bag or bottle seal. general 3 hours or so can be in addition to the tide, so that the electronic table to return to normal. for damp serious form can be extended to absorb moisture time.。packed in plastic woven flexible container，lined with plastic film bags锂聚合物电池保养，shipped in container锂聚合物电池保养，20bags for each。about 33-million tons of plastic are thrown away in the united states every year. plastic plates, cups and containers take 69 25 percent to 30 percent of space in america's landfills. one styrofoam cup takes more than 1 million years 70 (recycle) in a landfill, according to cleveland state university.。
