Hey everyone!!
EDIT: Yes you read that correctly. I’m willing to pay someone for some good advice helping me choose the settings. I can PayPal you money if you’re willing to help me answer the questions on my second post below.
———————————————
I’m so excited. This is the end of the 5-month project!! Once this is finished I can finally move the boat out of Panama and head back home to Florida.
(*See next post down below for my questions about settings. I really need your help with them please.)
BACKGROUND: I’m finally reaching the end of my 5 month re-install of my LiFePo4 system. If you haven’t been following my other posts, I’ve completely replaced almost all the old cables and cheap breakers on my boat with large 4/0 cables and proper fuses. I took out all 48 of the (6 year old) damaged LiFePo4 cells and capacity tested each one. And on Tuesday, I’ll be reinstalling them. I’ve tried contacting Outback Solar, CALB battery company, Victron Smart Shunt, Overkill Solar BMS, and Xantrex Inverter and asked them what my settings should be… and all the companies were worthless and couldn’t give me an straight answer or wouldn't answer at all. So once again, I turn to you, the REAL experts for your advice.
Here is info about my system:
- BATTERY/CELLS: I’ll have 48 CALB brand 100Ah LiFePo4 cells configured for a 12v system, 3P 4S. They will form four large 300Ah batteries consisting of 12 cells each. Each of the four batteries will have its own Overkill Solar 120A BMS as well as QNBBM Lithium Battery Balancers to help equalize each of the four 3P cells of each battery. (See attached pic of configuration)
- SYSTEM CAPACITY: Total nominal Ah would be 1,200Ah, however after capacity testing each cell, the total ACTUAL capacity of the system is now only 1,044Ah
- CALB 100Ah LiFePo4 SPECS: (see attached pictures of spec sheet)
