I agree with @DerpsyDoodler on this, I am tearing down a 16S2P pack with an intact Daly 16S BMS and rebuilding as two 8S2P packs even though i will spend twice as much for the new BMS units with all the accessories to make a complete system for the reasons listed:
1) redundancy.....the battery is the weakest link in my system, with two packs i will still have power even if one fails
one 200 a.h. pack is sufficient for my needs.
2) it’s never a good idea to have too many strings in parallel, too many fail points, with lead acid 2 or 3 strings of cells will work, 4 strings will rarely work as balance issues will pop up, same with lithium or any other type., going to 8S i would have 4 in parallel in each cell, monitoring gets difficult if not impossible, way more reliable to have a simpler system.
I already have a very parallel e bike setup that is a royal pain with @ 10S12P 18650 lilo setup, will change to LFP XS1P setup, KISS
3) I allready have very top end gear in 24 volt that are very efficient and far more reliable than any other brands, imho...
4) I do not have POCO power where i reside and have the worlds worst POCO at my shop location where i have a large battery backup system so i am not affected when we have a PSPS event......(Public Safety Power Shutdown)...whenever we have a windstorm or any weather event.....Im in Northern California where we have Pigs, Goats and Elephants as a power company as they need to pay the shareholders and not do a lick of repairs on the power network.
5) Through system redundancy i have had only one unplaned loss of power in 20 years when my Cotek inverter went away. Threw 2 switches, power is restored...
