Battery Notes and Tip:
Connect the battery as shown.
Disconnect the battery when not in use!
LiPo/LiLo: LiPo/LiLo batteries (lithium polymer / Lithium Ion) are high current rechargeable batteries. LiPo/LiLo batteries offer extended run time and peak performance over NiMH batteries.
They require a peak detection charger designed specifically for LiPo/LiLo batteries.
These batteries require special care and handling.
LiPo/LiLo batteries are recommended for advanced users only!
ALWAYS charge a LiPo/LiLo battery in LiPo/LiLo mode.ASSOCIATED MT12 Monster
