Cold starting in low temps

[Nilao]

I've been using a low frequency inverter/charger on my truck. It's a very small US based company producing them. The 2 guys designing them remind me of Rawze in so many ways, always tinkering with the code controlling them and redesigning the hardware to make it more robust. I've had it for about a year and other than issues that were causes by a bad chassis ground that caused my cab to use the inverter as a ground path it has been trouble free. It's a 6kw inverter and I have personally had it loaded up to 3300 watts between my microwave and fryer.

It switches between bulk and float modes depending on the programable voltages so you can charge LifePo, lead acid, or AGM.

Anyways that's my battery maintainer lol
