Hello,

I wished to upgrade to an AGM battery, as I plan on upgrading my 2016 Lexus ES350 with the following:

1. Apple CarPlay + Android Auto upgrade kit (possible upgrade to larger Lexus infotainment screen - though not sure at the moment)
2. 3 channel dashcam (front, telephoto and cabin)
3. 4 camera Mobile DVR (with 360 view)
4. Illuminated door sills + trunk sill
5. Rear view mirror camera upgrade kit (possibly - depending on how well integrated it is)

The upgrades are to make my car a bit more modern, as the car itself has been great and extremely reliable.

I've seen that AGM batteries require more power from the alternator to fully charge, and have seen people using voltage boosters.

I found 2 voltage boosters:

1. H113-L-2 Voltage boost harness - https://www.mechman.com/h113-l-2-vol...agm-batteries/
2. Voltage Booster PRO - https://voltageboosterpro.com/product/og/

The first is made to Lexus/Toyota spec (and is a cable that replaces the OEM cable coming from the alternator), while the second is like a fuse tap that sits in your fuse box.

When I contacted the people at Voltage Booster, they stated that their voltage booster was not tested on the Lexus ES350.

Whereas the H113-L-2 list the ES350 as being compatible.

I would assume both should work, but was curious which voltage booster you would all recommend?

Also, is a voltage booster even necessary (as I've read that the 2016 Lexus ES350 doesn't output enough voltage to properly charge an AGM battery per the AGM battery spec).

With all the electronics I plan on adding, I'm pretty certain I need to go with an AGM battery.

Plus, I rarely drive my vehicle (sometimes only on weekends as I tend to work remotely).

The AGM battery would seem like a good buy given my use case, but am worried that either voltage booster could damage the alternator, electronics or something else.

Any thoughts?

Thank you,
Nelson
