Li-ion battery 3.7v 18650 holder for Minelab explorer se / e-trac and other

Description

Hi! I have made holder for li-ion 18650 battery.It amazing thing, need only three battery(need to use with same capacity). And capacity of 3400mah are almost enough for
30-32hours
(5-6 days hunting). metal detector turn off at 8.8 volts( 2.9v per cell, no over-discharge).   orange color, easy to find if you lose it in field.
Compatible Metal Detectors: E-TRAC, Safari, Explorer SE Pro, Explorer SE, Explorer II, Quattro MP, Explorer XS, Explorer S.
!!!New model of holder, now you can use protected 18650 and 18650 with button top!!! And on some batteries with
flat top
for better contact between cells you need to cut
plastic on minus end(look on photo).
also lithium batteries don't have a “memory effect”. you can charge it when you want. don't need to discharge battery like NiMH
one battery 18650 3400mah cost 4-5usd. or you can get batteries from old notebook battery(ordinary six 18650 in one)
you no longer need dozens of AA batteries)))
shipping by avia with tracking number, like this RA123456789UA. arrive in 2-3weeks
batteries not included)))
NEW MODEL!!! Li-ion battery 3.7v 18650 holder for Minelab explorer se / e-trac and other
