Nope, different lithium batteries have different chemistry compositions.
A LiFePO4 will happily catch on fire if you charge it with the same voltage/current curve as a LiPo(3.6v vs 4.2v).
[edit]
To expand a bit, this[1] is a fantastic reference on exactly how complicated and involved the different chemistries can be. This is talking about Lead -> LiFePo4 but a lot of stuff applies to LiPo and other variants as well.

- snovv_crash 9y agoYou have to try really hard to make LiFePO4 catch on fire. LiIon just requires 0.5v of overcharge, but LiFePO4 usually also needs a case puncture, followed by a short circuit.
- ScottBurson 9y agoFrom your linked article: > Please note that in all 68 of these RUINED LFP banks, that I have to date, there was not one incident of fire, explosion or dangerous off-gassing. So you can destroy them easily by overcharging or other mistake, but LiFePO4 is probably the safest of the lithium chemistries as far as fire goes.
- vvanders 9y agoFair enough, I'm used to pushing the packs a bit harder on discharge so I swapped that around(charge/discharge).
