## Description

Product description LiFePO4 battery is a cleaner, More powerful and safer power solution 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. APPLICATIONS 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. 12V LiFePO4 battery have no liquid inside. This allows you to safely mount the battery where you want to place it. Rechargeable deep cycle maintenance-free LiFeP04 battery, Which is characterized by small size and light weight, Very suitable for fish finder, 10ah capacity can continue to provide a constant source of energy, So you can easily enjoy your fun.

Review: Phenomenal power-to-weight ratio and a robust 20A BMS—excellent workshop battery upgrade! - I picked up this NERMAK 12V 20Ah LiFePO4 Deep Cycle Battery to build out a custom, mobile 12V auxiliary power pack for my outdoor shop tools and high-flow pressure washer supply pumps. To handle outdoor overspray and demanding start-up currents safely, I paired this battery directly with the 12 AWG marine-grade waterproof fuse holders I reviewed previously. This setup has operated flawlessly, proving to be a highly efficient, lightweight power source that works just fine under continuous workshop load. Why this LiFePO4 battery is an exceptional energy upgrade: Shockingly Lightweight Footprint: If you are used to lugging around old-school 12V sealed lead-acid (SLA) batteries, switching to lithium iron phosphate is a total revelation. This 20Ah pack delivers twice the usable energy capacity of a comparable SLA battery at a tiny fraction of the physical weight, making it incredibly easy to integrate into a mobile tool carriage or camping rig. Dependable 20A Built-In BMS Protection: The integrated Battery Management System (BMS) is excellently calibrated. It monitors cell balance and protects against short circuits, over-charging, and deep over-discharging. It handles the continuous high-amperage current draw of my auxiliary water pumps with zero voltage sag, clicking off instantly only during genuine over-current thresholds to protect the internal cells. Flat Voltage Discharge Curve: Unlike lead-acid cells that suffer from constant voltage drops as they deplete, this LiFePO4 battery maintains a rock-solid, steady 12.8V output through nearly 90% of its discharge capacity, keeping connected pumps running at maximum efficiency right until the pack is empty. Workshop Wiring & Charging Tips: Always Pair with Circuit Safety: Because lithium batteries can discharge energy incredibly fast during a dead short, do not wire them raw. Follow my previous build steps and splice a dedicated in-line fuse holder (equipped with a 20A fuse to match the BMS ceiling) directly onto the positive lead wire right at the terminal. Utilize a Dedicated LiFePO4 Charger: Do not attempt to charge this with a legacy automotive lead-acid battery tender. Lithium chemistry requires a specific multi-stage charging algorithm (typically pushing a bulk charge up to 14.4V–14.6V) to properly balance the internal cells and hit that advertised 2000+ cycle lifespan. The big takeaway: NERMAK has delivered a premier, ruggedly housed power cell that offers an unbeatable combination of capacity density and safety features for a very reasonable price. The screw-down terminal posts are clean and provide a rock-solid mechanical connection point, the internal protection circuits are highly responsive, and the weight savings are massive. It is an exceptional value purchase that modernizes any custom low-voltage electrical build.
Review: Works great! - I needed replacement battery for my Tzora electric scooter, and the 25 AH lead acid battery pack. This barely fit into the enclosure of the lead acid battery, I had to modify it somewhat, so I could not recommend it for that use. In other scooters, it should fit great. If you are handy with tools, then it might work great for you as well. It seems to offer a higher voltage than the 25 AH lead acid battery, the voltage always reads top of the range in the volt meter. It does not sag as much when going up a incline. It feels more powerful than the 25 AH battery it replaced. But it also has the problem of shutting off when the voltage is low, not just slowing to a crawl when the voltage is low like a lead acid battery. It is a safety feature of all lithium battery packs to shut themselves off at a low voltage cut out. Just be sure to recharge it more often. I would expect a longer range than the 25 AH lead acid battery, and many more recharges than lead acid style battery.

## Questions & Answers

**Q: With two of these hooked together can it be charged with 24 volt charger?    yes or no.**
A: Yes,It is possible to charge two 12v batteries connected in series with a 24V charger, our Lithium ion battery has a voltage of 12.8V, you may have to use a 25.6V Lifepo4 charger to fill the battery, if your charger is 24V, one of the batteries will be undercharged, causing an imbalance in battery charging, I hope my answer can help you!

**Q: What is recommended max charge current?**
A: LiFePO4 should be charged or discharged under 0.5C (0.2C preferred). For a 10Ah version with 128Wh. You should charge it no more than 3A (preferably 2-3A).

**Q: Will this work with a trolling motor and for how long will it run ?**
A: Thank you for your question, our batteries can be used in a trolling motor, but I don't know how powerful your trolling motor is, so I don't know how long it will run, our batteries are 128Wh, if your trolling motor is 100W, it will last for more than 1 hour, I hope my answer can help you.

**Q: Got a shoprider Jimmy electric chair, will these discharge to the extent that you cannot recharge them like the lead acid batteries that come with it?**
A: All batteries will do that eventually.  The advantages of these are they will tolerate 80% discharge per cycle before any degradation (as opposed to 50% for lead-acid). and they offer many times the cycles.  I can’t speak to their suitability for your application, though.  They’re only 10AH each.

### ⭐⭐⭐⭐⭐ Money will spent.
*by R***S on May 2, 2026*

So far so good. This is the second battery I buy from this vendor, and after observing good performance over a year or so, I felt compelled to write a review. The first battery was used for a kids ride on jeep running at 12V. This second battery was to upgrade that same ride on toy to 24V by connecting to the older battery in series. It seems the overcharge, overvoltage, and fault protection in the BMS circuit actually works. We have done all of the above and it still works. I didn't do a formal leakage test, but I know for a fact that it holds charge well over decently long periods of time and cold weather. As long as they don't change their process and material, it's totally good value for your money.
