I got this battery pack to pair with VIOFO A329s. I went with this kit since it supports native parking mode with VIOFO cameras without any spliced cables, and potentially hybrid parking mode in the future with support for battery voltage via bluetooth. The battery is quite large but it snugly fit under the seat of an Integra Type S. According to the app, it takes roughly 40 min to fully charge from 20% which is quite fast. Any regular commute should be plenty enough to last the whole day at the parking lot.
One minor ding for this kit is that it only came with 1 add a fuse cable for low profile mini and standard fuses. Strangely enough, the micro fuse did come with 2 add a fuses so maybe it is an early release snafu. I ended up stripping one of the cables to use my own add a fuse kit since I did not have any spare quick connect add a fuse on hand.
