need some opinion/advise.
about to hit the "buy" button for the 70mai M300 dashcam because i read from a lot of reviews that gave this a commendable review for its price and plus, it's marketed by a reputable company. i understand that the only downside to 70mai is that the dashcam uses Lithium Polymer instead of the more desirable Super-capacitator so exposing it under long hours of sunlight may not be recommended.
my car is parked under shade (front porch in my home and basement parking in my work place).
are Super-capacitators really that far superior compared to Lithium Polymers?
Should i avoid Lithium Polymers like a plague or it is actually usable?
Addon: supercaps also have issue storing the power for long time. It's power will discharged faster than lithium. Which means it's won't work long under parking mode. That is why ddpai's parking mode now they must have hardwire kit in order to work.
Here is how parking mode in DDPAI mini3 works for those interested:
How mini3's parking monitor works:
1), When car engine is on, the camera will start to record normally based on 30FPS;
2), When car engine is off, the hardwire will detect the voltage change and then the camera changes to parking mode 1FPS time lapse recording immediately;
3), When car battery voltage lower than 12.4V or 12V or 11.8V ( you could choose in APP ), then the hardwire will cut off power automatically;
4), The defaulted maximum time of parking monitor is 24 hours, i.e. no matter if the voltage of car battery lower than the set voltage or not, the hardwire kit will cut off power automatically;
