How is difference fail-safe or minimum voltage between li-ion semi-solid stage and li-po battery.?

[Ekanat_Prasert]

about my set-up

1. LI-po 12S 2P , 16,000 mah 50v (4.20v / cell)
   set the minimum voltage for fail safe to 42.0v

2. Li-ion semi-solid state 12S 2P , 16,000 mah 48.8 v (4.10v/cell)
   So, what’s the appropriate minimum voltage for fail safe of Li-ion semi-solid state 12S 2P.

Ask the manufacturer, they know best.

As a general rule, Shawn made an excellent guide here:

Parameters related to battery chemistry

Here’s the whole run-down: Batteries Hi Crt Lipo 4.2 3.3 LipoHV 4.35 3.3 LiIon 4.1 2.8 These are the generally accepted values. Some LiIon cells may have a slightly different critical voltage, but all Lipos are the same. In MissionPlanner Initial parameters (and the spreadsheet) BATT_CRT_VOLT = (bat critical voltage + 0.2) x no. of cells BATT_LOW_VOLT = (bat critical voltage + 0.3) x no. of cells BATT_ARM_VOLT = (no. of cells - 1) * 0.1 + (bat critical voltage + 0.3) x no. of…

But you should check with the manufacturer, especially the minimum voltage under load.

LiPo’s are a very well known quantity, and they’re all the same really.

LiIons are different from manufacturer to manufacturer so check the specs for the exact voltages - particularly the usable minimum voltage that the cell can recover from.
If in doubt use the generic LiIon values in the Initial Parameter calculator in MissionPlanner.
