14s Pack Size
#1
Hello everyone
I have been working on a 18650 14S setup for over a year....   Takes time LOL
things I have now  
1) cell holders for 14S 120 P
2) 1.5 amp Axail fuses
3) 14G solid copper wire ( bus bars )
4) about 1500 good cells ( 2100mah to 3100mah) most of them are in the 2300-2500mah range ( I have another 1300 or so from 1500mah to 2000mah that are tested )


Tools that I'm using 
1) 10 Opus units ( testing units for MAH reading )
2) 10 Accucell 50watt Chargers ( pre chargers and Ohm testing )
3) 2 -Power Lab 8 units ( for when I need 60 amp charging..... LOL  ) balances 7s 60p rails for testing the batteries 
       before they set 30 to 40 day to see if I have any discharging cells

Now 

what size packs should I do ???    I want to use the batuirm BMS ( don't have the BMS yet )
twin 14s 60P     or make 14S 80P /100P /120P ???
I want the longmons to do there job....   So if I go 100P or 120P can a longmon keep that balanced ???

I'm to the point of building if I go 60P / 80P or 100P 
want to get it right the first time around...
What do you guys think works best with the Longmons ???

Thanks Avery !

If you have the cells for it, go for 120p. Smaller packs will likely require more maintenance and increase the amount of Batrium longmons you need to buy. A longmon should have no problem balancing a 120p pack. If you find it's balancing constantly due to pack voltages not matching, there is an issue with your batteries, such as a self-discharging cell.

I started with 120p and even that wasn't big enough for me so now I'm doing 300p, although I would probably recommend 2 longmons/pack if you go that route with used cells Smile
oooo
