Ensures Charging in Cold Conditions with Automatic Heating

When charging a battery in cold conditions, the power supply first heats the battery heating pad inside the battery. When the battery is heated to 10℃/50℉, the heating automatically ends and charging begins. The automatic self-heating function, activated by the BMS when charging between -20°C to 5°C (4°F to 41°F), ensures charging and reliable power backup in cold weather. This feature offers reliable battery charging conditions by reaching the set temperature in 40-70 minutes from -10°C (14°F) and 80-120 minutes from -20°C (-4°F). This ensures reliable power for your marine needs, even in harsh conditions.

The best upgrade you can make!

I recently got a new boat and the first thing I did was ditch that heavy lead-acid deep-cycle. This is lighter and gives 2x the capacity to run the navigation lights and the fish finder. I also use Litime to run my trolling motor. Use code FLORIDA6 and that will take 6% off your Litime order.

Post bolts too short for cable stack

Batteries are nice that they're a lot lighter however the post bolts that came with them were approximately half the size they needed to be by the time you put a stack of cables on them. They are metric so I was able to locate some longer specialty stainless ones at Lowe's and make it work.
