    • 6V 4Ah LiFePO4 Battery
The 6V 4Ah LiFePO4 Battery has proven to be an exceptional choice for powering various applications, offering unparalleled performance, durability, and efficiency in a compact package. First and foremost, the battery's LiFePO4 chemistry ensures superior longevity and reliability. With a lifespan of over 3000 cycles, this deep cycle battery outlasts traditional AGM and SLA batteries by a significant margin. This longevity translates to reduced maintenance and replacement costs over time, making it a cost-effective investment for marine applications, cars, RVs, golf carts, solar systems, and trolling motors. The compact size and lightweight design make installation straightforward and hassle-free, fitting seamlessly into existing battery compartments without additional modifications. Despite its size, the battery packs a punch with 25.6WH of energy, providing ample power for extended periods of use without compromising performance. I appreciate the advanced Battery Management System (BMS) integrated into the design. The BMS ensures optimal charging and discharging, protecting the battery from overcharging, over-discharging, and short circuits. This intelligent management system enhances safety and reliability, giving me peace of mind knowing that my equipment is protected. The versatility of this LiFePO4 battery is another standout feature. It performs exceptionally well in diverse environments, from marine settings to off-grid solar installations, delivering consistent power and reliability under varying conditions. Overall, the 6V 4Ah LiFePO4 Battery is a superior choice for anyone seeking a dependable deep cycle battery solution. Its robust construction, extended lifespan, and efficient performance make it ideal for both recreational and professional applications.

    • Works well for powering 6V Game Cameras
Most of my trail cameras are 6V and eat up AA batteries 8 at a time. Changing out these batteries can get expensive and reduce the dependability of the cameras. An alternative to the standard 8-AA batteries is the use of a larger 6V battery or a solar panel with 6V power storage incorporated. To use an external power source, most cameras have a female power jack. 6V usually uses a 3.5x1.35mm plug. This battery is small, light weight, rechargeable, and has the capacity to power most cameras for over 6-months without recharging. So far, this battery is doing well and has helped the reliability of my cameras. ... show more

    • Tiny little battery

This is a tiny little LiFePO4 battery. I got it for a little RC toy and it seems to work for the power, but the much lighter weight makes the RC toy a little unbalanced. I think it was designed for lead acid batteries so that the weight acts as a ballast to weigh it down. Not a fault of the battery. I may end up adding some extra weights to rebalance it. This battery arrived at 6.6v. I can't confirm the 4Ah rating, but it does run the RC toy for a pretty long time. The BMS doesn't seem to affect usage that much compared to some other batteries with BMSes that I've used. I have not had this long enough to comment on the 3000 cycles rating. ... show more

I plugged it into my load tester (the last battery before the tester bit the dust!) and threw a 2A load at it. It delivered almost exactly 4Ah of capacity after being fully charged. Because I was curious about what was inside, I opened it up. The cap appears to be sealed to the base and the battery secured inside with black hot glue. There is also a foam spacer to keep things from bouncing around. Inside are a pair of "ITR26/70-40e" 26700 cells in a 2s configuration with a BMS/PCB, presumably providing overcharge, undercharge, and overcurrent protection. ... show more

    • Great for testing 6V car/motorcycle electronics
I needed a good value battery to mimic the lead acid when I do testing on my Suzuki Fa50, a 6V moped. This battery works well and probably could be used in other systems with ease; the battery is light and has worked well for the past few weeks of testing.

    • Give new life to your old lantern battery equipment
When comparing my 6V sealed lead acid (SLA) battery with this LiFePO4 I find they are equivalent right down to the physical size. The only exception would be their difference in weights which are 1.475 lbs for SLA and 0.56 lbs for the LiFePO4. I load tested the LiFePO4 for around 4.7 hours until its' battery management system shut it off. Beginning voltage and load - 6.56V @ 680mA. Shortly before shut off - 6.34V @ 660mA You're getting a good value with performance like that above. With some creative wiring a battery like this could easily give new life to your old lantern battery equipment. ... show more
