      It's very easy to install if you have a little experience with a solder. The mosfet works great and is very reliable. Precocking feature is amazing with highspeed gears setup. You may need a crimping tool for the motor connector. I use YouTube to show me how to install it. It should not be too hard for most people.

      They give you plenty of wires,some heatshrink (I could have use another piece of shrink), 2 pieces of connectors,and a really good instruction manual.Few minutes of measuring,some soldering and it is working just perfectly.I Installed it in a AK12 and the whole process took 30min with hop up bucking change too.

      This is proof not promises,
      I put the perun ab++ in a DMR which is built from an ordinary AEG. The first try were a failure, because the original motor was too weak for the 150 spring, and the motor has stuck. The protection in the chipset is saved the motor from the sudden death.
      I love the functionality of it, mostly the burst fire modes,
      The cables what is coming with the chip is really high quality. It is very flexible. Easy to work with.
      The set contains everything what you need for the setup,

Perun Mosfet AB++

General, short description
AB++ is an on-wire mosfet, channeling the power from the battery to the motor through a specialized high-power transistor, instead of delicate mechanical switches, increasing reliability and replica performance. It also enhances your replica by adding many new, useful features.
Works with 7.4V, 11.1V and 14.8V batteries. Comes almost fully pre-wired, with only few easy soldering joints needed to install the mosfet.
Features:
Electronic burst
Active brake with adjustable braking power
Precocking (with spring release feature)
Rate of fire reduction
DMR mode
Low battery voltage alarm
Programming supported with a multicolor LED diode
Diagnostic system
Electronic resettable fuse

Feature description
Electronic burst - Change auto to an electronically controlled burst to save your ammo and increase realism!
Active brake - active brake stops the motor after each shot preventing spring compression or in case of replicas with high rate of fire, overspin (double shot problem).
Precocking - Fast trigger response can be a matter of victory or defeat, especially in CQB situations. With precocking enabled, piston will remain in rear position after each shot with the spring already compressed, ensuring that next shot will be fired immediately after you pull the trigger. To release the spring after using precocking, pull the trigger while simultaneously holding button on the unit. A shot will be fired, with no precocking and fully braked.
Rate of fire reduction - Reduce the rate of fire in automatic or burst fire to save ammo or make the replica shoot in a more realistic fashion.
DMR mode - Introduces intervals between semiautomatic shots to comply with DMR rules on some fields.
Low battery voltage alarm - Dedicated for Li-Po and Li-Ion batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals that are repeated every minute. This may also be freely switched on and off.
Diagnostic system - Constantly monitors the replica and the mosfet itself. In case of any problems, immediately lets you know what it might be, making troubleshooting much easier.
Electronic fuse - Will save your replica and battery in case of a major malfunction. It will automatically disconnect the battery if a short circuit or blocked motor is detected.

Programming of all the settings is done solely by using trigger and a button on the device, in an easily memorable and quick sequences. Programming is supported by sound signals and multicolor LED diode. That allows changing the settings in any moment, in a matter of seconds, even under enemy fire.
Upgrade kit works without problems with any battery from 7V do 17V. It can also be used with most extreme setups, without any limitations as to the spring rating.

ATTENTION! Do not leave your replica with the battery plugged when is not in use, because of the risk of complete battery discharge (which will permanently damage the battery).
This can also cause a damage to the mosfet itself.
