Features

  • Low-temperature Cut-off ProtectionThis 12V 20Ah lifepo4 lithium marine battery supports a cold cutoff function, which stops charging when the battery temperature is detected to be below 32F and stops discharging when the temperature drops to -4F, thus ensuring that the battery is protected from damage even in cold conditions.
  • Grade-A Battery Cells & 20A BMSOur 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 (75C).
  • 10-year Lifespan & LightweightOur 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 Use12.8V 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 and electric scooters.

  • This battery far exceeds the advertised voltage output duration for my application!
Style: 12V 30AH
I use this battery to power my 25 watt marine radio. I tuned in the NOAA Weather channel & turned the volume off. Sixty hours later the Actual battery voltage was 13, One good feature of this battery is that it can be charged with a solar set-up. Its small size & light weight combined with the built in protection features & the two year warranty make it an ideal choice for my kayak. ... show more

  • Nice product
Style: 12V 20AH
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. ... show more

  • Perfect!
Style: 12V 30AH
Perfect battery. I run livescope and a 9 inch graph on it. Do not need to recharge until the 3rd day. Running it 6-8 hours a day. Light weight and small.

  • Battery No Good
Style: 12V 30AH
Just over a month after installing, this battery made a loud pop, and my UTV wouldn’t start. Checked it with a voltage meter and it reads 4 volts. Swapped battery back with the old one, and the unit fired right up. Must return battery. Very disappointed and wouldn’t recommend purchasing.

  • Works as advertised at 1/3 the cost of name brand options.
Style: 12V 20AH
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. ... show more
