Battery Specifications 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. NOT APPLICABLE Please note! Our battery is not a starter battery, it can't be applied to motorcycle, go-kart, generator, lawn mower, trolling motor, jump starter, UPS above 1500VA/1000W, scooter above 24V 350W, etc. The working current of our 10Ah battery is 10A, the maximum can't be more than 15A, because the current is longer than the battery's working current for a long time will damage the battery. 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: 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.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great cost for an effective replacement. *by D***S on 14 August 2025* Although slightly shorter in height than original batteries, work like a charm.

I installed them in my Cyberpower CP1500PFCLCD UPS as a test to see if they would both fit and power the unit. The fit test worked great. I was concerned that the dimensions listed for these LiFePO4 batteries were slightly larger than those listed for the OEM batteries. I tested functionality both plugged in and unplugged with the UPS powered on and everything seemed to work as it should. I then connected the UPS with my electronics and turned it on (connected to the AC power) and everything is working OK so far. At present, I see no reason why Cyberpower ups owners shouldn't use this battery substitute instead of the OEM lead-Acid version but I will update this review in the future if I encounter any issues with these batteries. Afterthought: While the mfgr doesn't recommend this battery solution for UPS above 1000 VA, I felt confident using it in a 1500 VA unit because my electrical loads are very light compared to the UPS rating AND I have whole home electrical backup so the UPS would not have to carry the load using the batteries for more than 2 seconds when an outage occurs. I don't know if I could honestly recommend this solution for someone who relies solely on the UPS for backup during a long outage with over 1000 watts of load connected. Be sure that you will only expect light loads during any outage if you decide to install these batteries in your UPS. For those wondering why I even use a UPS with whole home backup: The delay to switch to the home backup can take as long as 2 seconds to kick in when a grid outage occurs. The ups switches much faster (~ 20 ms) and keeps my electronics powered during that short delay. ## Frequently Bought Together - Nermak 2 Pack 12V 10Ah Lithium Ion LiFePO4 Deep Cycle Battery, 2000+ Cycles Rechargeable Battery for Solar/Wind Power, UPS, Scooters, Lighting, Power Wheels, Fish Finder Built-in 10A BMS - ULTRAPOWER 4-Amp 14.6 Volt LiFePO4 Battery Charger,12.8 Volt LiPO Lithium Battery Charger,Smart Charger Maintainer for Cars,Motocycles,Golf Carts,UAV,Fishing Boat and Deep Cycle Batteries. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/608174109-nermak-2-pack-12v-10ah-lithium-ion-lifepo4-deep-cycle](https://www.desertcart.sk/products/608174109-nermak-2-pack-12v-10ah-lithium-ion-lifepo4-deep-cycle) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-28*
