I want to get a GPS device. Requirements:
- 12V input
 
- At least 1000mah battery. Ideally with a 18650 battery cell.
 
- as slim as possible.
 
- not too expensive :)
 
- optionally 4G compatible.
 
- obviously traccar compatible.
 
Any suggestions?
What I have found so far, in a random order:
- Sinotrack:
- ST-901L-4G - 150mah battery too small.
 
- ST-905L - only 5V input - need extra stepdown module.
 
 
- Topin:
- CT3 - 2G only. Could quite easily change battery for a 18650
 
- ZX905 - Bare PCB module, that supports LTE CAT-1. Could add a 18650 battery or even two, but would need extra 12V to 5V stepdown
 
 
- Teltonika:
- FMM920 (probably best quality, but not sure if worth the monies)
 
- TAT100 / 140 / 141 (big battery, but no power input?)
