After having 6 Tattu lipos get damaged in the past month from relatively mild crashes, I started contemplating ways I could protect my lipos, without adding a lot of extra weight - While I was at Walmart looking for double-sided tape, I had a brainstorm as I glanced at the stationary section - In front of me were these interesting items called 'Plastic Insert Dividers', which my mind immediately created a mock-up of how it would look, and work. After testing on the 2 6s Tattus I have left, I decided the idea was definitely solid enough to share, so here you guys go!

Items needed:

• Plastic insert dividers (From Walmart, or any stationary store)
  
• Scissors
  
• Thin double-sided tape
  
• PVC heat shrink tubing (I use 90mm for 6s batteries)
  
• Heat gun
  

This was the lightest option I could think of, and it definitely makes the battery more durable!

Tattu lipos usually seems to prioritize weight over protection and most FPV LIPO batteries come with little or no protection.

RC buggy and RC robot hobbyists usually use cased lipos but these tend to be heavier for airborne stuff.

My first lipos were CHNL Blacks (1300mah 6s), and they had a similar plastic shroud around them, and they lasted just over a year before the cells started dropping off (After MANY crashes) - I figure if I'm going to be getting a lot of 'soft pack' lipos, I have to do something to make them more durable - I tend to take a lot of risks when flying, and the batteries always suffer the most 

Oscar posted a blog post where he shared a few options: https://oscarliang.com/protect-lipo-battery/

I use the battery landing pad TPU print option for my quads with bottom mounted lipos.

I thought maybe wrap them in part of a rubber bicycle inner tube. It should give the external armor and some protection against being pierced.

But for me, the best solution, would be to not mount lipos on the underside of quads.

Problem is on some builds like my Merica 9" and the Switchback Pro 5", top mounting lipos is not even remotely possible unless we cut a custom top plate.

Most racing frames and tootpick frames have been designed with bottom mounted lipos in mind.

In reality there is no safe top or mounting option for lipos.

The choice of top or bottom mounted lipo will be dictated by the kind of flying was the quad frame designed for.

For racers, they prefer bottom mounted lipos as they fly at such high tilt angles that the top plat is the first thing that rams into a gate or obstacle.

On freestyle quads a top mounted lipos are preferred since there is a lot of quick catch it off the after a power loop or doing a wall drag etc.

On an Xclass quads there are some designs like the CMW Cannonball where the frame is large enough that we can mount lipos inside the frame. A really safe frame for lipos but a monster of a quad for most pilots.
