- When used correctly, Lithium ion/Polymer/Fe battery packs are as safe as any other type of
rechargeable battery pack. However, these batteries do require different charge regimes than the more
established Nickel Cadmium and Nickel Metal Hydride technologies and have the potential for catching
fire, if severely mistreated.
- If Lithium Polymer battery packs are short-circuited or severely over-charged, elemental Lithium may be
deposited internally. If the battery pouch is damaged, elemental Lithium can escape from inside the
battery. If this occurs, a fire may result. Elemental Lithium is highly reactive with exposure to water or
moisture, producing flammable hydrogen gas and corrosive fumes. Elemental Lithium is only produced
with severly mistreated battery packs. During normal usage, explosions or fires are extremely rare.
- 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 have full
nominal capacity and a reduction in performance is likely. Allowing the voltage to fall below 3 volts per
cell will invalidate all warranty claims.
- Never charge Lithium Polymer battery packs to values exceeding 4.2V per cell, Lithium Ion batteries
exceeding 4.1V volts per cell or LiFe batteries exceeding 3.7V per cell. Exceeding these recommended
values can cause irreversible damage to the cells and will invalidate all warranty claims.
- Never charge Lithium battery packs at rates exceeding the maximum charge rate, as damage to the
pack can occur and this process may be very dangerous. Generally, Lithium Polymer packs should
not be charged above 2C (2 x Capacity).
However, some newer packs do allow charging at rates up to 5C. Charging at these excessily high rates
will reduce the life of the pack.
(e.g Pack of 2500mAh capacity : 2C = 5000mAh = 5A max)
- Do not use discharge rates in excess of those specified with the battery pack, as a significant
drop in voltage under load will occur that can dramatically reduce the number of
charge/discharge cycles that the battery pack will hold.
- Disposal of the Lithium battery packs requires that the pack be completely discharged.
Use a light bulb, electric motor or similar to completely discharge the pack.
Do not allow a Lithium battery pack to short-circuit! A short-circult may result in a
minor explosion with a consequential fire.
- Before charging Lithium battery packs, inspect closely for any damage, such as punctures in
the sleeving or swelling (expanding) of the battery. Do not charge if any damage has been
detected, even if the battery otherwise appears to be new and unused.
- Before starting the charging process, double-check the settings on the charger to ensure that
the correct parameters have been entered for the specific battery pack that is 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.
