Battery tube short

Battery tube short for 3 pcs 21700 for 3 times longer burningtime

The short thicker battery tube, can be used on all Maxi uni lights to extend the burning time of the LED modules about 3 times longer.
If e.g. used an LED module 3600-50000-15, resulting in a burning time of about 270 minutes, instead of about 90 minutes with the standard short battery tube with 1 piece 21700/26650
The battery tube contains a battery holder for the 3 pcs 21700 batteries. The batteries must be removed from the battery holder to charge them in the charger. A direct charge in the battery tube to charge from the outside, is currently not possible, but it is possible by an upgrade later.
 
Note: To increase the lifetime of the 3 pcs 21700 batteries, the following points should be noted:
- all batteries from the same manufacturer
- All batteries have the same capacity
- All batteries have the same number of charging cycles
- All batteries are the same age
- All batteries should always be used together in the battery tube
- DO NOT mix batteries, e.g. different age of the rechargeable batteries leads to a reduction in the lifetime of the rechargeable batteries
