What battery should I use in my EVO?

Ah, the age old question: what battery should you use in your EVO. It's not exactly clear cut, and we've been getting a lot of questions about it, so we've got in contact with the chaps over at ASG Denmark and got the information directly from the guys who made it. If you've ever been confused if you should use a 7.4v, 9.9v, or a 11.1v battery in your EVO then this blog post is for you!


Why can't I use an 11.1v LiPo in my EVO, it's rated for them!

You'll find a lot of information on the internet, in both Facebook groups and on websites saying you can use 11.1v out the box, though this is technically correct, its not correct for the UK version of the evo.

When you buy an EVO in the UK they have a lower powered spring in them to bring them under the UK limit of 350fps.

Because there is less resistance from the spring the gun fires faster, so using an 11.1v LiPo can cause timing issues in the gearbox. ASG recommends that if you have a gun which is under 1J (the UK variant) then you should use a maximum of 9.9v LiFe[1].

If you can't get your hands on a 9.9v LiFe, a 7.4v LiPo will do just fine.

So I can never use an 11.1v LiPo in my EVO?

All is not lost, if you upgrade your EVO to higher than 1j it is possible to use an 11.1v LiPo without issues. Even though the EU variants of the EVO come fitted with the higher power springs and spring guides everything else internally is the same.

If you replace the Standard Spring and Spring Guide with ASG official parts then the replica will work just fine on 11.1v over 1j.

Typically though in the UK, if your rifle is over the 1j limit it will probably be a DMR, something most EVO users will not do.

So what battery should I use exactly?

As as rule of thumb, if your EVO is a stock UK variant then use a 7.4v LiPo or 9.9v LiFe. If your gun is upgraded over over 1j or is a DMR, then use an 11.1v LiPo.

Basically: If your gun is new out of the box use a 7.4v LiPo

If you got it from us USE A 7.4v LIPO!

How do I swap my spring and spring guide?

To replace the spring you simply remove the spring guide when the stock is removed, then change the spring. For more detailed please see the ASG Guide:

What will the ASG EVO warranty cover?

We got in contact with ASG and they've let us know that as long as the replica is within specification it can be repaired at any ASG Certified Tech Center.

If your replica conforms to the following rules it can be repaired under warranty.

  • If the Evo is a UK Spec < 1j version, then only 9.9v LiFe or 7.4v LiPo should be used
  • If the Evo is an EU Spec > 1j version, then only 11.1v should be used
  • If the Evo is a UK Spec Evo, but is upgraded > 1j using ASG Certified parts

Hopefully that answers your questions. Remember, if you ever need any help do not hesitate to get in touch. You can call us on: 01484 644709, or email: sales@patrolbase.co.uk, we're more than happy to answer any of your questions.

      The difference will be the rate of fire on full auto. You wont notice much difference between a 7.4v LiPo and 9.6v.

      To be honest, im not sure any Ni-Mh battery would fit in the Evo any way, so you’re limited to 7.4v LiPo anyway, so problem solved 😛

      Hope this helps
