I am using this to power my 100w ham transceiver. Well made, excellent performance and longer run time than I will ever use. Reasonably light weight for it's size. For ham use, you can not charge while plugged in due to RF noise from charger. That is a minor nit in a situation most people will never encounter.

June 1, 2024: Updated Review for the KEPWORTH 12.8V 50Ah BMS LiFePO4 Batteries in My Hoveround MPV5 Wheelchair I'm delighted to share my ongoing experience with the **KEPWORTH 12.8V 50Ah BMS LiFePO4 batteries installed in my Hoveround MPV5 wheelchair. After **three months of daily use, I'm pleased to report that these batteries are **still going strong! Notably, not even one power indicator light on the joystick has dimmed or malfunctioned during this period. The consistent performance and reliability have significantly enhanced my mobility and peace of mind. As I continue to use these batteries, I'll diligently monitor their performance and provide further updates. Rest assured, I'm committed to sharing my honest assessment, no matter how long it takes. Thank you for creating a product that positively impacts the lives of wheelchair users like myself! 🙌🔋 March -14-2024 Updated review for the KEPWORTH 12.8V 50Ah BMS LiFePO4 Batteries, installed in my Hoveround MPV5 Wheelchair: Review: KEPWORTH 12.8V 50Ah BMS LiFePO4 Batteries I recently upgraded my Hoveround MPV5 Wheelchair by replacing the outdated 12V 31Ah Deep Cycle Gel Batteries with the KEPWORTH 12.8V 50Ah BMS LiFePO4 Batteries. Here are my thoughts: 1. Performance and Power: * The KEPWORTH batteries deliver impressive power. With 50Ah capacity, they provide extended runtime, allowing me to use my wheelchair for longer periods without worrying about recharging. * The BMS (Battery Management System) ensures safe operation by preventing overcharging, overdischarging, and short circuits. This feature gives me peace of mind. 2. Weight and Portability: * These LiFePO4 batteries are significantly lighter than the old gel batteries. The reduced weight makes handling and installation easier. * I appreciate the compact design, which almost fits seamlessly into the wheelchair’s battery compartment however the slight difference isn’t an issue still straps down. If this is an issue for others I recommend just getting a lower Ah. For me though the power is worth it! 3. Durability and Longevity: * LiFePO4 chemistry is known for its longevity. The KEPWORTH batteries claim 4000+ recharge cycles in deep cycle applications. * While I haven’t used them for that long yet, I’m optimistic about their durability based on other users’ experiences. 4. Flexibility: * The ability to wire these batteries in series and/or parallel configurations is a major advantage. It allows me to adjust the circuit voltage as needed. * Unlike my previous gel batteries, which were limited to 12 volts, the KEPWORTH batteries offer more flexibility. 5. Value for Money: * Considering the reasonable price point, these batteries provide excellent value. They offer high-quality performance without breaking the bank. * As someone who relies on a wheelchair daily, I appreciate the reliability and cost-effectiveness. In summary, the KEPWORTH 12.8V 50Ah BMS LiFePO4 Batteries have been a solid upgrade for my Hoveround MPV5 Wheelchair. If you’re looking for reliable, lightweight, and long-lasting batteries, I recommend giving lithium a try! Remember to consult your wheelchair’s manual and follow proper installation procedures when replacing the batteries.

So far good, short time frame but one battery connected to a 4000 watt inverter used for whole house power. With 2 computers and monitors running along with 2 TVs and 2 routers plus fiber router including various lights and one short run of microwave the battery lasted a little over 2 and a half hours. I think this is pretty good but not much experience with this type of set up. Ordered another battery and will add that to the existing setup and see how it does.

This was the most awesome battery that one could purchase. I bought mine on a Black Friday sale. I live off grid and the discharge rate, weight and functionality is extremely impressive.

Fast, accurate delivery and the battery charged to full capacity as advertised. Have yet to use it on my kayak yet as it's still freezing cold. I will review the battery later in the spring but it does work and has full charge and full volts.

I bought this battery because I liked the charger it came with and the easy buttons, however; after several uses it stopped charging and I had to reach out to the seller for a warranty, it turned out to be my charger wasn't working correctly. The seller was very responsive and agreed to reveiw it and work on it under warranty and then shipped it back. I used it just the other day and its working great.

I bought my first LiFePo4 battery from this company last summer. It continues to work great for me. My power needs increased this year, so it was time to buy another, larger battery. When I had purchased my first battery from them, I contacted customer service with a question, and 'Jessie' was most helpful. So, now that it was time to buy a second battery, I decided to contact the helpful customer service rep again and discuss my needs. Once again, Jessie was most helpful and suggested a slightly different battery than I had been looking at. I have been using this battery now for more than a month, and I could not be happier. Thank you yet again Jessie! One minor thing that I was a little surprised about. This battery comes with its own charger. It seems to work fine, no problems. But, though the charger is labeled with all of its power input/output specifications, I could not find anything related to a manufacturer, model number, manufacture date, lot, etc. on the charger itself. Like I said, it works, but I had just never seen a power supply so NOT labeled before. I just found it humerous, that's all. I will definitely continue to use this company for my LiFePo4 battery needs.
