These 12V lithium batteries are a great replacement for my old lead acid batteries. My absolute favorite feature of these batteries is not having to worry about 50% depth of charge. I can bring my batteries down to 0% and enjoy the full battery.


Shawn Griffin  Verified Buyer

I have 3 100ah 12v batteries for a 36v trolling motor, and 1 125a battery for starting and electronics. The first use of my batteries was on a (4 Day) fishing trip that the wind blew every day.We fished from early morning till dark every day and NEVER had to change the batteries the entire trip. I still had 45% life on all three trolling batteries and 92% on my electronics battery when I headed home.

I live in a cold area and this was important to me. The batteries arrived quickly at 13.2V with a 70% charge. This seems like a great option for my new solar project.


Luis C.  Verified Buyer

I used it all day and night in the caravan and the voltage is still 12.8V, much more durable than my old lead-acid batteries, I'm very happy to change this lithium battery, and I believe LEAD-WIN, a Chinese manufacturer brand, will not let me down.
