HTC EVO 3D Otterbox Maximum edition - HTC EVO 3D

Do you want Maximum Protection and Maximum Batterylife Yet you can only choose one or the other. well ive got news for ya . Introducing the Otterbox MAXIMUM edition Extended Case
This otterbox DEFENDER series Sets a good example for other phone cases on how they should be built. this case fests a Wamping 3500 Mah Hyperion Batterypack and Fits absolutely perfect Without even violating a percentage of protection.
This case took 2 hours to prep and 2 hours to make.
The case was a success !.
And now for the pictures.

Awesome! Just what I've been looking for. Gonna Google this to see how much it cost.

---

I'm afraid its doesn't exist till now . I crafted this whole design except the patent patent of otter boxes design

---

Ah, makes sense now!

---

What's protecting the battery's heat from the rubber?

---

some type of heat resistant tape. there are just a few things left that I have to do to complete it-

---

Maybe Otter will see this and start developing something like it! I would love to have a 3500mAH with the protection of the case.

---

Yeah I have like 4 of those for free.
Sent from my PG86100 using xda premium

Nice work man,
I did a mod like this on my defender for the hd2 HERE the case for that phone is a slightly different design + the battery is right in the middle of the case which helped.
I just did one for the Ballistic for the EVO which isnt as tidy but has been going strong for about 2 months.
I want to do a V2 of the ballistic a bit tidier this time .
Did you have to cut your backplate? I used the remainder of the extended one I used for the "bulge"
pics below>
EDIT Inspired by posting here last night, I was up late in the workshop V2!
Bottom 3 pics are the re-worked mod.
More people should try this mod on either Ballistic or Defender it takes some skill and the right materials but its totally do-able

Guys keep this up! I definitely need a case for this 3500 battery. I dropped this phone twice today. Face down! My luck may run out if I do it again.

Glass didn't break phone worked fine But made my guts rolll

I always carry my phone with the screen facing outward in the Otterbox Defender holster/clip. You can't even tell there's a Seidio 4000 battery in there. My phone looks absolutely stock.
I'll posts some pictures when I get some time.

Yeah man, throw some pics up soon, I love these mods!
one of the reasons why I got the evo3d over the sensation was the Extended battery/rugged case potential

---

Here are pictures of my 3D with the Seidio 4000.
First picture shows the back of the 3D.
Second picture shows the inside of the holster. It was dremeled to allow the bigger battery to fit comfortable.
Third picture just shows the phone sitting on the holster.
Fourth picture shows the phone clipped inside the holster. You can't even tell that there's a big fat battery inside there. =)
The last few pictures shows the cradle that i made out of pvc pieces. Besides not having to take the phone out of the case, you can angle the phone forward or backward when watching videos so it's very convienient.
(I've also made a simple mount out of plexi glass for my car that will work with the 3D inside the Defender. Which I will take pictures of and post after I get my car back from the body shop sometime this week.)

---

So is anyone going to put a tutorial on how to do these mods? I would really like to protect my phone with this beast of a battery on.

---

I wish I had taken photos as I was making the mods, but I didn't think about it. However, all you really have to do is SLOWLY cut out the back of the cover with a dremel tool.
*edit*
Oohaylima - if you were planning on using the 3500mah battery, then you don't have to dremel out the inside of the holster or cut the rubber on the case, bcuz I didn't have to when I had my 3500, but that battery didn't work as well as the Seidio 4000. I was trying to save a few bucks by buying the cheaper battery but in this case, you really do get what you pay for.

i have the same case and battery but i havent done this and i was wondering if the battery stays in or does it fall out

The holster is what keeps the battery in. So if you use the case with the holster than it shouldn't be a problem.

Right! That's one of the worse feelings in the world when it comes to damaging a vital electronic device.
