Tokyo Marui 7.4V 800mAh MS Li-Po Stick Battery (Pre-order, December 24, 2025)

*This battery can only be used with Tokyo Marui electric guns that are compatible with MS/Li-Po batteries (stick type).

Highly safe Li-Po battery with built-in protection functions and temperature sensors

• Slim Li-Po battery

  This 7.4V 800Ah Li-Po battery is cold-resistant and has low self-discharge. It's slimmer and more compact than conventional nickel-metal hydride AK batteries. Its high output also improves the response time between pulling the trigger and firing the BB.

• Equipped with a temperature sensor

  The battery has a built-in temperature sensor, which allows chargers and electric guns compatible with MS/Li-Po batteries to detect the battery temperature and stop operation if the battery temperature is abnormal or outside the operating range.

• Cell management with internal circuitry

  The internal circuitry of the battery manages the two series-connected cells, monitors the voltage of each cell, and charges appropriately for cells that are deteriorating, preventing further deterioration when connected to an electric gun.

• Equipped with five protection functions

  The battery is equipped with built-in protection functions to protect the battery and the user from problems such as overcharging, over-discharging, and short circuits. [1] Over-discharge prevention function [2] Over-charge prevention function [3] Discharge overcurrent protection function [4] Short circuit protection function [5] 0V (zero volt) charging prohibition function

• Hard case protection

  The battery is protected from external impacts by a flame-retardant PVC hard case, preventing damage to the battery that could cause smoke, explosion, or fire.

• [!] Please be sure to use products compatible with MS Li-Po batteries.

  Be sure to have the dedicated charger "MS•Li-Po Safety Charger" (sold separately), which is equipped with various protection functions, and the fireproof bag "MS•Li-Po Safety Bag" (sold separately) ready just in case.
