Lithium ion battery pack. If TEMP pin''s voltage is below 45% or above 80% of supply voltage VIN for more than 0.15S, this means that battery''s temperature is too high or too low, charging is suspended. The temperature sense function can be disabled by
Voltages | Li-Ion & LiPoly Batteries
If you want to take your project portable you''ll need a battery pack! For beginners, we suggest alkaline batteries, such as the venerable AA or 9V cell, great for making into larger multi-battery packs, easy to find and carry plenty of charge. If you want to go rechargeable to save money and avoid waste, NiMH batteries can often replace …
Is it possible to put a higher voltage battery than recommended?
It means that your 11.1 V battery (composed of 3 cells in series) has a real voltage of around 3 x 4.3 V = 12.9 V when fully charged, which is higher that the maximum voltage of your NiMH battery. Without knowing the circuit and the maximum input voltage it can tolerate, it is better not to try it.
