Great addition to my jump starter

Based on my experience, this intelligent regulator makes using my jump starter so much easier. It provides a clear and accurate readout of the battery's status and controls the charging process perfectly. I appreciate the safety features that prevent overcharging or damage to the battery. The only downside is that it is a bit bulky, making storage a bit challenging.

Pros
  • Accurate readout, controls charging process, safety features.
Cons
  • Bulky design for storage.

It's not as advertised. CAUTION

This is not a mppt controller, it is a pmt controller, the advertisement was wrong. I want my money back. It is not as described.

Pros
  • memory function
Cons
  • replacement availability

Intermittent 5 to 20 volts on battery

I installed this on a 100 amp lithium battery and a couple of solar panels. I also had an investor connected. The feeder keeps switching off, even when the sun shines all day. I check the system voltage and the voltage fluctuates from 5 volts to 20 volts every second or two. Thought the battery was dead. I unplugged that controller and hooked up another controller to the battery and never had a problem since. So my conclusion is: This controller didn't work properly.

Pros
  • Multiple Protection
Cons
  • Fits
