Home solar system

So far it’s all good. We are having particularly cold and cloudy days. New Li batteries are holding charge thru cloudy days and nights. We’ve had one sunny day out of 4. We are satisfied. Thank you.

This is a new system for me

I replaced 4 Trojan wet cell batteries from a solar system at my camp. I will need to change several components to work with the new LifePO4 battery. I need to learn a new system. The battery worked very good when I hooked it up. I was able the run a Cpap for a friend all night for two nights in a row with very little charge during the day. But I still will need to refine how I charge up the new battery.

Power to spare.

Added third 200 ah to my travel trailer. Quick to charge with solar. Great for boom
docking. Replacing boat batteries with Weize deep cycle as soon a budget allows.
Great Product!

LiFePO4 battery experience

Delivery was prompt. No problem setting it up in my small battery bank. We've just experienced some cold nights here, way below freezing, in the teens. My batteries are in a enclosure in an unheated space. I'm learning that these batteries don't charge in cold temperatures. Will have to figure a way to heat my battery box.

Perfect Upgrade

Bought a boat that had a small flooded cell marine battery and old Minn Kota. Bought the new iPilot and battery. Was leaning toward AGM for the bang for buck, but decided on this lithium as weight is significantly different, and makes a difference in a smaller aluminum boat.After practice days and a full day tournament on the water with the wind blowing 20+, this thing has been incredible. Ran the trolling motor all tournament and it had plenty left when I put the boat on the rack. Can’t speak to longevity yet, but so far it’s been perfect.
