What heat shrink do I need?

[Darkstar826]

I want to buy the heat shrink as soon you answer my question.

My battery is 18650. 10s 3p.
This is my layout.

What size I need?

[tech.shit]

130mm will be perfectly fine, especially if you can keep the pack flat while wrapping it

[Evwan]

Mmmmm I disagree. 130 is the width of the pack, the heatshrink has to be substanceally larger. 180-200 is a safe bet.

[tech.shit]

think 150 could work?

[Evwan]

Heatshrink can shrink, no point of cutting it close. 200 is very easy to obtain on Amazon, so I’d just use that. I use 220mm for my 4p 21700 packs. This is a bit more narrow, so going down to 180-200 will be fine.
