8.4V NiMH

The 8.4V NimH battery is one of the "safest" batteries you can choose because the voltage can be tolerated by any replica.

The NimH battery is also one of the user-friendly batteries you can get for your airsoft replica. A NimH battery can be used till it runs completly dry without damaging the cells, this is not the case with LiPo batteries. The NimH during the day will perform less and less and therefore in performance gradually more and more.
