Maxi uni battery tube PRO for 3 x batteries

Battery tube PRO triple for 3 x 21700 batteries for triple burn time

The thicker battery tube PRO can be used on all Maxi uni lamps or can be retrofitted .
If, for example, an LED module 3600-50000-15 is used, the burn time is approx. 270 minutes , instead of approx. 90 minutes with the standard battery tube.
In the battery tube there is a battery holder for the 3 x 21700 batteries .
The batteries must be removed from the battery tube to charge them using USB-C or the charger.
The Akkurohr PRO has various mounting options .
There are three holes in the bottom of the battery tube, where you can attach an eyebolt , mount the handle or attach a safety rope .

Note: To increase the lifespan of the 3 x 21700 batteries, the following points should be observed:
- 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

-> so that the charge difference and thus also the voltage difference is as small as possible, so that one battery is not loaded more than the others.
