To that end I purchased an XZNY 20Ah LiFePO4 battery and this 5A charger, that does not throttle down to a lower voltage when the battery is full as others do, with the intention of modifying the output to 13.5V so that it will not damage the cells when left permanently connected. The charger instructions state that it should be disconnected after the battery is charged, which makes sense for preserving the capacity of the battery but may also be to preserve the charger components. Nonetheless I observed less than a watt (my instrument’s resolution) of quiescent power and I see no cause for concern in keeping it plugged into AC power. Someone else here mentioned that he modified his charger voltage (thanks packetrat!), so this charger seemed like a low-risk choice.I first opened the case, then pried up the circuitboard, sometimes using a knife to cut through the flexible glue used to hold it down. I then located the surface-mount LM324 quad operational amplifier and R104 (14.7k), which is the top half of a voltage divider (3k to ground on the bottom half) and is used to compare to a 2.5V voltage reference. I calculated that a 195k resistor in parallel with R104 would change the “battery full” voltage from 14.4V to 13.56V, but I wanted to chose that option with a switch, so I soldered wires at convenient places (see photo) that are equivalent to either side of R104. The other photo is of the switch: two 1% resistors in series (180k and 15k), and an ugly reworked solder job (I got it wrong the first time). If the voltage option were available through some fancy menu (it’s not), it might not remember the setting when the AC power is interrupted, so a simple toggle switch is best.When I started testing the charger as part of my uninterrupted power supply, I was dismayed that around 10W load (guesstimate) the fan would slowly turn on as higher charging current resumed. It’s loud. So I put in a replacement fan: 40mm, 12V, 14dBA, made by Scythe (SY124010L). Others may work better for less money. There is no 2-pin connector; it must be soldered in. What a difference! Now I can’t hear it at all. I’m sure there’s a little less airflow but I don’t expect a lot of heat buildup for my use case and I could never get the heatsinks very warm.Two weeks later and I have no complaints. The load is usually under 2 watts and the voltage is steady around 13.5V, perhaps a little lower depending on which DVM I use. ### ⭐⭐⭐⭐⭐ Works well. *by K***M on March 19, 2025* Works well. The clips for the charging cable and the charging cables themselves are a little underwhelming. Not sure about long term durability. It does the job though and the entire unit is small enough that it fits into my small radio bag without adding any serious bulk. ### ⭐⭐⭐⭐⭐ Great low amperage LiFePO4 charger *by C***D on December 13, 2024* This charger is great, specially for slow charging if you have a large capacity battery. It does use constant current charging then the current decreases as the battery get closer to 100% charge. Good value, I recommend it. Does not get hot while charging. It does have a fan, not very noisy. --- ## 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.ma/products/207095297-12v-2a-charger](https://www.desertcart.ma/products/207095297-12v-2a-charger) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-05-03*
