Red triangle, check engine, multiple misfires, slugish at times, help :'/

Previously i had owned a 04 prius great car did alot of repairs on it but kept it on top of things, unfortunately i crashed the car, i survived unscaved thankfully, recently i got a 05, and im getting very weird problems ive tried diagnosing it but here are the simptoms

Red triangle, check engine and brake light at one point abs light, i took it to autzone for they're free scan stuff i got misfires on all 4 cylenders codes lead me to replacing ignition coils and sparkplugs, i did all 4 old coils and sparkplugs where worn, unfortunately it did not fix the issue

At times trying to accelerate the car seems to stall a bit, the hv batt has been stuck at 1 bar but it throttles at highway speeds just fine most of the times, car drives in ev mode for about half a mile or so when the the battery shows its almost full, after triangle and lights it stays at 1 bar, the issue leaves when i unplug the 12v and reconect it during nightime vehicle runs fine most of these issues have been at day time when its hot, i checked the inverter pump and its fine working, im already down to it being a battery failure on the highvoltege one, ill soon try and replace cells its not recommend but the guy i bough it from had cells replaced 7 months ago and gave us ones in good condition according to him, either if any of you has input that would be great, i also wonder why the misfire codes persist even when all 4 sparks and coils where swaped thank you!

227k miles in the odometer

 

There is no direct engine noise that would lead me to belive that is the case, nore is there smoke coming from the exhaust either, which is good to some extent...
