Lithium LiFePO4 Charging

I'm upgrading from two T-105 Trojan flood batteries to a GBS 200 AH Lithium LifePo4 battery bank with BMS.  Would you recommend using my Renogy MPPT40CC solar charge controller on GEL setting.  GBS Lithium battery can be charged to 14.4 volt but most recommend 14.1 volt.






GBS 3rd Generation Li-ion Batteries Product Specifications:

- Nominal Voltage: 12.8V (4X 3.2 V)
- Nominal Capacity: 200 Ah
- LiFeMnPO4 chemistry
- Operation Voltage Range: 11.2 to 14.4V
- Weight: 24.9 kg or 55.0 lbs
- Dimension: 500 X 259 X 142 mm or 19.25 X 10.2 X 5.5 in
- Max Charging Current: 3C
- Max Discharge Current: 3C (continuous) / 10C (pulsed)
- Cycle Life : >2000 (80%DOD)
- Operating Temperature: -20 to 65 C or -4 to 149 F
- Self Discharge Rate: <3% monthly
- Accessories included: jumpers, screws, washers, split washers and
cell covers


• Advantage of GBS 3rd Generation Li-ion Batteries:

- High energy density by weight and by volume.
- Superior safety performance due to patented new safety valve and pressure
cap designs.
- Dual Safety Valve Design, one On Each End.
- Batteries do not explode or catch fire when batteries are shorted or punctuated
resulting in internal shorts.
- More robust connection due to new electrode terminal design using four screws
per terminal; Prevent loose connections caused by vibration.
- Reduced impedance due to improved electrode terminal design;
- Long cycle life.
- New cell structure better facilitates battery pack formation.
- Superior cold weather performance. Lab tests show 90% of rated capacity at -20�C.
- Terminal design increases high current performance for longer sustained
continuous current.

first of all - good question - but there as been no answer since December 2014?
i have a question for anyone out there...
i also have LiFePo4 batteries - 2 - 4-cells used on a 24V system.
i'm using a Custom setup for parameters, but i've never been able to confirm that i'm doing it correctly.
since LiFePo4 batts have slightly different specs than regulare Lipo's and i've read that Gel settings is NOT recommended, i'd really like to see a breakdown of the parameters that should be used.
also, (and i've written about this today) the software "Solar Station Monitor" download file is corrupted. i WAS using an older version of that, but recently it's been having communications problems. - but to that end, it would be GREAT if a firmware update were added so that the parameters for LiPo and LiFePo4 systems could be setup with default parameters!!! thanks,

WOW Man those are some awesome looking batteries and they sure have a hefty price to boot... What is the real advantage to using those batteries???
