unless the battery pack is severely mistreated, so in normal usage there is no
likelihood of explosion or fire.
Lithium Ion/Polymer battery packs must NEVER be discharged below 3 volts per cell
(Li-Fe 2.0V) as this will result in damage to the cells. If the voltage is allowed to drop
below 3 volts per cell the battery voltage may seem to recover following a charge,
but the battery may not then give its full nominal capacity and a reduction in
performance is likely – allowing the voltage to drop below 3 volts per cell will
invalidate all warranty claims.
NEVER charge Lithium Polymer battery packs at greater than 4.2V per cell, Lithium
Ion at 4.1V volts per cell or LiFe at greater than 3.7V per cell as this will cause
irreversible damage to the cells and will invalidate all warranty claims.
NEVER charge Lithium battery packs above their maximum charge rate. This can
damage the pack and can be dangerous. Generally, Lithium Polymer packs should not
be charged above 2C (2 x Capacity). However, some newer packs do allow charging at
up to 5C, but charging at these higher rates will reduce the life of the pack.
e.g Pack of 2500mAh capacity : 2C = 5000mAh = 5A max charge current.
DO NOT use discharge rates in excess of those specified with the battery pack as this
will result in a significant drop in voltage under load and will dramatically reduce the
number of charge/discharge cycles the battery pack will give.
If disposing of Lithium battery packs ensure that the pack is fully discharged by using
a light bulb, electric motor or similar to completely discharge the pack.
DO NOT allow any Lithium battery pack to short-circuit as this is likely to
result in a minor explosion and consequent fire.
BEFORE charging any Lithium battery packs they should be closely inspected for any
damage, such as punctures in the sleeving or if the battery has swollen or expanded
in size. If any such damage is detected DO NOT charge, even if the battery otherwise
appears to be brand new.
Before commencing charging ALWAYS double check the settings on the charger to
ensure it is set correctly for the battery pack to be charged. Using the wrong settings
is likely to result in damage to the battery pack being charged and could result in the
battery catching fire.
