## Description

Review: Great cost for an effective replacement. - Although slightly shorter in height than original batteries, work like a charm. I have replaced the batteries in a 90's fold n go power scooter with these amazing little gems. Can and does still use its original charger, battery pack is now half the weight of what it used to be, and packs quite the punch. Installed very easily by swapping everything over to the new batteries, fully charged in very little time and scooter that had been sitting for years was back on the road.
Review: Update - failed within 1 day - Update 4 days later, 10/11/2024 Well...this did not work out. The battery arrived and was installed on Monday, just before Hurricane Milton struck Wednesday night. After a1/2 second test crank (which was fine), the battery was connected to a new LiFePo4 battery charger designed for this battery chemistry. The charger itself may be suspect, as the battery would not accept a charge. The charger displayed a fault mode after a few hours. I then connected it to a known good charger. After a charge of several hours at 2amps, the charger had to be disconnected as we prepped for the storm. A quick check on Tuesday (the next day) found that the generator would not start. Did not have time to do diagnostics with the storm coming. Had to pull-start the generator after we lost power Wednesday evening. Did diagnostics today, Friday 10/11. No problem with the starter motor, as it started immediately with my portable jumper pack. The Nermark battery showed less than 10V on my DVM. Both chargers displayed a battery fault, and were unable to charge the battery above 10.3V. It's possible there was an issue with the built-in BMS (Battery Management System), but I don't know. It's getting returned once Whole Foods is open again. Original Review 10/7/2024 Very simple installation to remove the old sealed lead acid 12-18 battery and replace it with this one. I have been using LiFePo4 batteries in my RC aircraft for over 20 years and I'm glad that this battery is available to replace the typical unreliable lead acid battery that is used as a starter in portable equipment. I took the opportunity to install the terminal rings and cable for the appropriate 3 amp charger and even without completing the charge, did a quick test start on my generator. I hope it will last several years, as this generator is only used for hurricane emergencies. However, I have batteries of this chemistry that are over 20 years old and still hold 80% or more of their charge. I will report back and update this review in the event that there are any failures, or possibly great news to continue to report years from now.

## 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.

### ⭐⭐⭐⭐⭐ Wonderful Upgrade Over Gelpack Power
*by W***K on January 26, 2026*

Wow! After getting only a single season out of conventional gel pack 12v batteries I bought this one to use on my Vexilar FL-18. For only a few bucks more it works great. I fished three days straight in a wheelhouse without charging the Nermak battery. I can't recommend it highly enough. (Be sure you have a charger designed for lithium batteries)
