PoE Trap builds without Void Battery

Hi - I'm quite casual. This is the first league I've sunk a lot of time into the game in a while. I suck at dodging mechanics and need to be decently tanky to enjoy the game. Is there anything I can do to improve my damage on my build that doesn't break the bank? Should I realocate some points in my tree? I run despair on hit because I map and it's more a quality thing. I self cast despair/temp chains on bosses which I think overrides cast on hit (unless I misunderstand the mechanic) I have about 5 div but would be willing to farm more. [

New and better POB: Edit: After subsequent testing upon advice given by a couple of you in the thread I have made adjustments to the build. Master of Metal has been dropped and I've picked up First to Strike and Last to Fall. Adrenaline is procced with a dual midnight bargain swap. + impale count DOES NOT work with traps. Old and apparently fucked POB (its the POB shown in the video but it's also shittier):

I just hit 100 with my Ice trapper and I've only done the bare minimum boss fights to unlock my voidstones. Now, I want to try to get better at bossing and learn more boss fights. I see a lot of Ice Trappers using Void Battery and a bunch of other uniques to maximize their power charges. Is this the play? Some of them are doing insane dmg!! I currently have 30 div to start this transition and wondering what items to start with. Thanks! My current POB:

Thoughts on divergent lightning trap voltaxic rift occ?

BOSSING: You must have a Cold Iron Point, or a dagger with +1 Phys and Dot Multi to use blade trap. Obliteration is for mapping, CIP is for pinacle boss farming/completion

I like to suffer early game, here is something I cooked up (probably wont even work but w/e). Here is the link: If anyone has a better tree path or suggestions lmk!
