the following comments in the video are greatly appreciated:
- Use with both lead-acid and lithium batteries,
- The cheap controller it comes with being up to the job,
- Adjusting the voltage up on older lead-acid batteries to remove build-up from the plates.

From what I know, the difference with using a controller with different battery types is having the ability to change the charge voltage to the battery which the cheap controller seems to have the ability to do...i.e. Li batteries need a higher charge voltage that might boil a lead-acid battery
Some 120 VAC to 12 VDC battery chargers have the ability to De-Sulphate a battery which I always thought was the ability of the charger to give short pulses of high voltage which was supposed to knock off the sulphate accumulated on the plates... the video suggests higher voltage to the plates but at short pulses??? I don't know.
I have a cheap controller like that on a 25 watt solar panel I have on my small fishing boat... it seems to work just fine for the last 5 years. I often use the built-in USB port to keep my phone charging when out on the water. The panel sits horizontal on the deck and only charges the battery for a few hours when actually out fishing, supplementing the alternator on the motor.
I viewed the review yesterday and it seemed like a decent alternative at a fairly attractive price point. If you have interest I would keep an eye out for black Friday discounts and check out the HoboTech guy's webpage for more up to date coupons.
