Product Description

LiFePO4 battery is a cleaner, More powerful and safer power solution

4.5a-1

LiFeP04 batteries are maintenance-free batteries, If you need them all the time, Then lead-acid becomes too unreliable and laborious, The battery's lithium-ion properties reduce the weight of traditional lead-acid batteries to less than half, While significantly improving performance and capacity, Traditional lead-acid batteries contain large amounts of lead, After disposal if not properly disposed of, Will pollute the environment, While lithium materials without any toxic or hazardous substances, Recognized by the world as a green battery, Its great durability allows you to easily use them at home and at work, Or safe outdoor needs , The environment is most important.

Recommend using a professional LiFePO4 charger to charge the battery so that it can be charged to its full capacity (existing lead-acid battery chargers (wet, AGM or gel) will also work fine)

Lithium ion batteries can be discharged up to 100% without causing damage. Make sure to charge the battery immediately after discharge. We recommend limiting the discharge to 80-90% depth of discharge (DOD) to avoid disconnection of the battery by the BMS.

6V LiFePO4 battery have no liquid inside. This allows you to safely mount the battery where you want to place it.

I bought a farm that had a TSC DEER FEEDER, However the battery was dead. I looked on the TSC website for a replacement. They wanted $40 for a replacement battery. I ended up with 2 batteries here on Amazon for half the price and they charged quickly and are doing a great job I highly recommend these batteries. Great purchase and great quality!!

These are a perfect replacement for not only our solar fence charger, but also fit a UV lamp model UVSL-26P sold by Analytik Jena US. The portable Geology UV lantern claims to require factory removal and replacement of the battery. I inquired about getting my lamp's battery replaced, and Analytic Jenna US replied with a cost of $95 plus shipping to replace the battery. Replacing the battery was as simple as removing thirteen screws and easily removing and replacing the battery for a quarter of the price.The next day, I had to replace a battery in a solar electric fence charger, and conveniently this battery is also an exact replacement. Well worth the price so far. If these batteries turn out to be duds, I will update the review. For now, they appear to be working as well as the original Panasonic 6V 4.5Ah batteries.

My son's bumper car stopped working. The original battery would not charge. Even if I used different chargers. I decided to try this battery, and good thing that it works. Right size, fits perfectly. All I had to do was use a hot glue gun to keep the wires from moving. That's how the original cable was from factory, glued on the negative post. Would recommend for any parents experiencing their kids bumper car that won't charge.

I bought this for my deer feeder to replace one of the old style heavy 6-volt batteries that had died after years of use. This battery while inexpensive, does not hold a charge very long compared to the old battery. The old one would last a couple of months or more before needing charge, this one is about a month. I am not too happy about it, but for the price, I chalked it up to you get what you pay for. I will be more selective next time. Overall, for the price it is not a bad battery, and it weighs just a few ounces.

We purchased this battery but never got to use it. It arrived with a charge of 4 volts, as measured by my Fluke multimeter, and just never took a charge. We swapped our charger to a different battery to verify that it was functioning properly, which it was, but on the brand new battery it didn't work. I'm not sure if this means anything but the weight of this battery was considerably less than some of the other ones we had of the same voltage/ amperage rating. Attempts to reach out to the company for a warranty swap went unanswered. Pretty ticked we wasted nearly $20 on this garbage.

These batteries are the future, for everything except heavy current usage. The internal circuitry shuts the down when abused, although short duration high currents are allowed for several seconds until things get hot (I suppose) , then a few seconds later, power is restored. I use them to power small motors with short surges of 10C and they cope well. The voltage stays so constant it makes other battery chemistry look stupid. And they seem to hold their charge forever. No wonder they are coming to EVs. If there is a better chemistry coming, it will be real game changer all round, as these are already way better than anything else, so far.
