Sunny Bounder with Heavy Scyk and Linked battery costs 18 points. Throw on Pulse ray shield for an even 20 if you want it.
But how does the battery interact with her ability?
Unlike a TL, LB cant "reroll 0 dice" so you cant use it to turn hit/focus into triple hit, without an actual die roll. But that die roll is still a 3/8 chance of getting triple hit, and there's only a 2/8 chance you'll be worse off if you reroll that focus. (really, same goes for rerolling the crit in a hit/crit roll, as long as you have a focus to spend.)
So how likely is sunny to get triple hits? Lets do the numbers. (assuming focus)
----------------
TLDR:
Totals:
Triple Crit: 12/512
Triple hit: 218/512
...for a total of just under 45% of attacks at triple result
Hit/Crit: 62/512
Double hit: 84/512
...for an additional 28% of results
