An exceptionally high quality Li-Fe battery pack.
9.9V Li-Fe batteries are relatively new to the airsoft market, and bridge the gap between 7.4V and 11.1V Li-Pos nicely; where 7.4V is too little and 11.1V is too much.
These battery packs have a similar power to weight ratio to lithium-polymer (Li-Po) batteries, but are far more tolerant to over & under charging. In extreme situations where a LiPo battery may ignite, a LiFe battery will most likely just vent some harmless gas.
This pack comes in a shape not much larger than a NIMH small-type with a decent 1600mAh amperage.
These battery packs are far superior to many competing brands, especially those low-cost types sourced directly from Far-Eastern retailers.
Each pack comes with guidance notes on what to do / not do to get the best performance & life expectancy.
A high 1600mAh rating for long lasting power.
Only 103.5mm x 34.6mm x 17.5mm in size, allowing it to fit anywhere a regular small-type NIMH battery will fit.
Fitted with a standard small female Tamiya connector.
Requires the use of a LiPo/LiFe charger.
Great looking luminous blue wrap.
The battery is supplied with detailed instructions for safe use, charging & storage, please take a few minutes & read them carefully.
We recommend the use of a charger like this.

Li-Po/Li-Fe battery warning: Always charge your Li-Po/Li-Fe battery in a fireproof bag. Charge your Li-Po/Li-Fe battery on a hard, solid surface and away from other electronic devices. Only use a Li-Po/Li-Fe battery charger and never leave a battery unattended, even in another room.
