I can't confirm that was the pack voltage it reached, only that one cell was pushed over Vmax and triggered the alarm. The 192.5v is the pack theoretical abs max voltage if all 50 cells are charged to 3.85v.
I was watching the highest cell voltage on BMS and forced charge was pushing one of the cells over the VMax 3.85v.
The pack V was probably substantially lower and one cell was out of balance so went over V as it was fully charged.
One full charged at 3.85v but others could have all been around 3.2v which gives a pack V of about 165v
From other users experience these Li-fepo4 cells generally remain at 3.2v over most of the charge curve but then V rises rapidly at the end.
I need to burn off some charge and then try it
I need to clag a few more meters on the pack and watch things closely with the people visiting today that may be a bit easier.
It's all very early days of course
I'll add a dvmm to battery terminals today and compare readings from BMS, also need to add my current clamp meter to check BMS current sensor accuracy.
Let's not jump to any conclusions at this stage
