What are the dangers of using 18650s in parallel. I know if they are used in series, reverse charging is a danger. How about in parallel setup, such as the Fenix TK35? Is there any danger of reverse charging or explosions?
The TK35 is a series setup, not parallel.
How is series vs parallel determined?
From the electric connection between the batteries, usual this is also reflected in the physical layout:
Series:
+battery-+battery-
+battery-
-battery+
Parallel:
+battery-
+battery-
HKJ
Then can you confirm if the TK35 is series or parallel?
Thanks. Love your reviews!It is in series and the battery holder does include part of the driver (or maybe all of the driver). This means that the output voltage from the battery holder is not the voltage of two batteries in series, but about Vf of the led.
