In terms of a better charger and getting more
batteries for around the same there may be a better option.I'll put the links below for you.
You can get the Vamo here from Exhale Vapors:
VAMO Variable Volt/Watt APV V2
Use discount code
40PercentOffECF at checkout to bring the price to about $40.
EFest IMR
batteries and a good charger from RTD Vapor:
18650s:
Batteries : Efest IMR 18650 Button Top
Those are $8.49 - so $17 for two.
18350s:
Batteries : Efest IMR 18350 Button Top
$6.59 each, so $13.20 total for two.
A good charger:
Battery Chargers : Xtar WP2 II
$20
Total: Vamo $40, 4 batteries $30, Charger $20 = $90.
Or less depending on what batteries you intended to buy. I noticed the Smoktech price went to $80 with just two batteries and a charger. The Trustfire TR001 chargers are ok, but they take a really long time to charge batteries. It can be 8 hours sometimes. The Xtar charger I linked above is quicker for the 18650s - a few hours max.
