I have some LiFePo4's on order. Here is what Trimetric told me:
We have a link below to the TM-2025's User Manual. In it you'll find, on pages 6 & 7, a description of all the 'P' parameters.
For Lithium LFP batteries, the changes needed are as follows:
P1 - 14.4 Volts.
P2 - 2% of P3 (battery bank capacity)
P3 - Battery Bank capacity in Amp-hrs
P7 - L3
P10 - 98%
P14 - 0.00 hrs

I also talked to PD re my PD4635 charger/converter. They said I should keep the boost mode button on.
