400D, do you have direct experience with making/using the conversion?
It would be nice to update my SLA to LiFe batteries,
I have been using 4 10Ah LiFePO4 cell in series for my Broncolor Mobil A2R for more almost 2 years, I can't speak for compatibility Profoto personally. The flashes manufacturers have been using LiFePO4 over LiPo/Li-Ion because it is safer.
I'm also planning to upgrade an exhausted SLA battery (in my case, for the original AcuteB 600). From the AcuteB2 manual, p.9:
... Because of their special construction it is possible to apply the same chargers for LiFe and Pb (lead acid) batteries; this simplifies the combined use of new and old battery generators and allows owners of previous Profoto battery generators to update their packs with the new LiFe batteries.
No mention of AcuteB pack upgrade for LiFe compatibility.
SLA end voltage for charging is 14.7V while LiFePO4 is 14.4V. Maybe this is insignificant, I would not use the same charger for them, over charging a LiFePO4 for over 3.6V per cell may damage it. The manual of AcuteB doesn't mention about LiFePO4 since this chemistry has been in the market only for a few years.
