Couple things.

Why no twins in P classes?

Why a single power source for a twin setup?

Please give me an answer smarter than "safety". Pretend like your talking to an FE guy instead of fuel guy please. Not buying "insurance".

A 6s twin on say 6k per bank requires that we bring two parallel packs together and then split them back apart. There is no safety gain but there is a ton more wire. More wire = more ripple current = hard on equipment for no reason I can justify.

Splain it Lucy.
