Best practice for charging LFP batteries on MG4 se

[gazza487]

Not one for me to helpfully answer BUT I have an early SR. After throwing all the sw updates at it - it behaved differently when balancing and I could cram a bit more in the battery hence got a few more miles out of it. There were specifically BMS updates applied too.

Balancing from a really low % can take ALOT longer now. 1st go after the updates was over 2.5hrs!

What charger were you using? From a very low start, a single phase charger should take something like 10hrs - a 3 phase charger probably 6-7 hrs!

I've just charged mine and balanced; this is what iSmart says:

Manual will tell you charging to 100% is recommended once a month for BMS to equalise cells. Saw a figure once which claimed the least degradation if you charge LiFeP between 75 to 45 state of charge.
