According to AimsPower, you can run up to 7 of these in parallel. I only have the generator for 2, so I'm getting 40 amps for my 400AH battery bank. My use is for home batteries and LiFePo 48v batteries. You should check the maximum acceptable input current for your situation so as not to cook your batteries. Being an off grid homeowner, I find this product a must own. Review: Powerful but loud. Lasts less than 2 months - 2 October 2022: I bought this charger on 9 September 2022. The charger is able to achieve max 19.1 amps higher than the rated 18.5 amps. The charging efficiency is around 80% even after using a step-down converter to convert 240v to 120v. The metal casing does gets pretty hot when running at full load hence the need for powerful fan. The only drawback is that the fan runs at full speed even when running at less than 50% load. 28 Nov 2022 Update: After less than 2 months of usage, problems start to emerge. When switching on, the green and yellow LED would light up (both solid) for about 62s indicating it is charging. But it isn't and the fan is not running. After that, the green LED would remain solid while the yellow LED blinks every 2s indicating it is on float charge BUT my LiFePo4 48v battery system is way below the 55.2v (around 50v-51v) specified on the operating manual for float charge. Email to the technical support on 18 Nov 2022 has went on deaf ears with no reply at all. So the charger has become an expensive USD275 paper weight collecting dust! ## Features - Multi Voltage Charging Flexibility: Selectable 36V or 48V output modes using a DIP switch, allowing one charger to support multiple battery bank configurations. - Three Stage Smart Charging Technology: Bulk, absorption, and float charging stages automatically optimize charging voltage to improve battery performance and extend overall battery life. - Multi Chemistry Battery Compatibility: Charges open lead-acid, AGM, GEL, and LiFePO4 batteries, making it suitable for mixed system upgrades and modern lithium conversions. - Wide AC Input Range for Unstable Power: Operates from 70VAC to 145VAC, allowing reliable charging from generators, shore power, and inconsistent utility sources. - 30 Years of Power Engineering: Put serious technical experience into your setup. Count on an established brand that stands firmly behind its products. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08KKNK4L9 | | Antenna Location | Home, Office | | Best Sellers Rank | #268,518 in Automotive ( See Top 100 in Automotive ) #714 in Power Inverters #931 in Battery Chargers | | Brand | AIMS Power | | Built-In Media | Battery temperature sensor port, AC input cord, dip switches for voltage selection | | Color | Blue | | Customer Reviews | 3.8 out of 5 stars 76 Reviews | | EU Spare Part Availability Duration | 1 years | | Energy Specifications Met | UL, CSA | | Included Components | Battery temperature sensor port, AC input cord, dip switches for voltage selection | | Input Voltage | 145 volts | | Item Highlight | 25A for 36V / 18.75A for 48V | | Manufacturer | AIMS Power | | Mfr Part Number | CON120AC3648VDC | | Model Name | CON120AC3648VDC - FBA | | Model Number | CON120VAC36/48VDC | | Number of Items | 1 | | Number of Packs | 1 | | Output Voltage | 36 volts_of_direct_current | | Peak Output Power Watts | 840 | | Power Source | Battery Powered | | Recommended Uses For Product | Home, Office | | Standby Power Shutoff | 80% | | UPC | 840271005744 | | Unit Count | 1 Count | | Warranty Description | 2 year manufacturers warranty | ## Product Details - **Brand:** AIMS Power - **Color:** Blue - **Model Name:** CON120AC3648VDC - FBA - **Power Source:** Battery Powered - **Recommended Uses For Product:** Home, Office ## Images ![AIMS 36V 48V Smart Battery Charger AC Converter 25A ETL CON120AC3648DC - Image 1](https://m.media-amazon.com/images/I/51gRkPnf31L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can this be connected to a 12v battery or a 24v battery pack?** A: No. This is a 36 or 48 volt DC charger only. **Q: Can the output voltage be adjusted? Meaning can I dial in 58.8 volt or etc, what is the voltage output for lifepo4 settings** A: The short answer is NO. This should be specified as a 16S LiFePO4 Charger. It is sad to see a manufacture like AIMS not understand that many LiFePO4 are 15S and that they might need 54V set point ... like the popular Renogy 48V 50Ah battery! **Q: What type of cables do I need to connect this to my Batteries?** A: We recommend 8 AWG cables between the charger and battery. **Q: What is the screw size for the terminal block?** A: The screw size is M6 standard. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple, effective. *by M***N on March 13, 2024* The first thing to know is that these are stackable.

And it works!! The charger is used on a 14s NCM lithium pack. Each cell is 4.1V @ 100% and this charger brings it right to that point. Any larger and this charger wouldn't be able to do it. It is a little loud but that wasn't a factor for me. So far its handled about 15 cycles. I use 4 gauge lead wires which is way over kill but that's what is coming out of my battery so I match the connectors. ## Frequently Bought Together - AIMS Power CON120AC3648VDC AC Converter & Battery Smart Charger 36V or 48V 25 amps - QWORK Battery Monitor Voltmeter Ammeter, Voltage Range 8V-80V and up to 500A, Voltage Current Meter with 13 ft Custom Cable --- ## 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.us/products/246371135-aims-36v-48v-smart-battery-charger-ac-converter-25a-etl](https://www.desertcart.us/products/246371135-aims-36v-48v-smart-battery-charger-ac-converter-25a-etl) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-11-10*
