## Features

- 【 Low-temperature Cut-off Protection】This 12V 20Ah lifepo4 lithium marine battery supports a cold cutoff function, which stops charging when the battery temperature is detected to be below 32°F and stops discharging when the temperature drops to -4°F, thus ensuring that the battery is protected from damage even in cold conditions.
- 【Grade-A Battery Cells & 20A BMS】Our lithium battery is powered by Grade A LiFePO4 batteries with higher energy density, excellent cycle performance, fast charging and discharging speed, charging efficiency of up to 100%, and no memory effect. The upgraded 20A BMS provides rugged protection against overcharge, over-discharge, overcurrent, overvoltage, overload, and short-circuit. With high temp cutting off prevents charging over 167 °F (75°C).
- 【10-year Lifespan & Lightweight】Our LiFePO4 lithium batteries provide more than 5,000 cycles compared to 300~500 cycles for lead-acid batteries, and have a 10-year lifespan that's 8 to 10 times longer than standard lead-acid batteries, helping you minimize replacement costs. Moreover, Li-Iron Phosphate batteries are 30% lighter than lead-acid batteries of the same capacity, so you can easily carry them to the destination you want to go! (Not a starting battery, not suitable for use as a power battery）
- 【Extendable Storage & Widely Use】12.8V 20AH lithium batteries can be expanded by series and parallel connection to expand the capacity, allowing expansion to 4 in series to get a maximum of 48V (51.2V) or 4 in parallel to get 80Ah capacity, it is recommended to connect no more than 10 in parallel. Widely used in most applications such as RVs, solar, trolling motors, boats, marine, off-grid.
- 【2-Year Maintance & 24-hour Service】VATRER provides a 2-year maintance for all batteries, we try our best to provide the safest batteries and the most professional service for every customer.

## Questions & Answers

**Q: Is this a group 20 battery?**
A: No it is not for automotive use. This is for a wheel chair.

**Q: Does the internal BMS on this battery prevent charging in subfreezing temperatures?**
A: I do not live in cold weather area. but from what i have seen on youtube alot of companies say yes and turns out no. I do not depend on the consequences of replacing it. when I have concerns of cold weather. I pui a high wattage for the area to keep the temperature up. they even have plug-in thermostats that come with automatic on temperature settings.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice product
*by R***N on September 6, 2023*

I bought this to use for my Livescope while fishing. Wanted a light enough battery to be portable but still have enough capacity to last a day of fishing.I have LVS 32 with Garmin SV93 graph. So far it has made it on all 3 fishing trips without dying.I am not positive yet but I suspect I could go up to 8-10 hours on a charge but haven’t had the chance to fish that long yet.Great value fir the money.

### ⭐⭐⭐⭐⭐ Works as advertised at 1/3 the cost of name brand options.
*by E***C on October 21, 2023*

After a couple of months of use this battery is doing terrific. I can't comment on if it will last for years but so far it has performed excellent.I use this in my Playmate Volley tennis ball machine and I was thinking it would be completely acceptable if it kept it running 2-3 hours of use. So far it has been used many times and a few times exceeded 3 hours of use while only getting down to 60% charged (my charger only indicates in 20% increments and I'm relying on it as the measure of charge remaining). It appears like it could last many more hours. This exceeds the lead-acid battery the machine is shipped with by a good margin. It appears to have the capacity advertised based on my usage.I was concerned about buying a battery like this at this cost point due to potential quality concerns. I still don't leave it on the charger overnight or such and keep an eye on it to be sure. But so far this seems to be a viable choice and has given me no reason to doubt the quality.

### ⭐⭐⭐⭐⭐ Great value

Good battery for a small solar project
