I want to keep the batteries between 80% and 20%** A: No. I don't think this is possible, unlesss you write a script that monitors the voltage or % of charge, and open a relay that would cut off the power input to the system... You would need some external equipment (arduino?) for that. **Q: Are the batteries hot-swappable? In other words, can I connect an external power supply and swap the batteries out while that is on?** A: Hi friend, Sorry that the X728 on board 18650 batteries does not support hot-swappable, please swap the batteries after power cut off. best regards, Geekworm Team **Q: Does the rtc have a separate battery? or does it run on the 18650 batteries? what happens if you remove them? will it "lose" time?** A: Hi friend, The RTC function runs on the 18650 batteries. It will "lose" time if you remove the 18650 batteries. best regards, Geekworm Team **Q: Can I use more than two batteries with the x728?** A: It holds two batteries, it does have an second input for more battery boards. ## Frequently Bought Together - Geekworm for Raspberry Pi UPS, X728 (Max 5.1V 6A) UPS & Power Management Board with AC Power Loss Detection|Auto Power On|Safe Shutdown|Battery Capacity Reading|Low Battery Auto Shutdown|Buzzer - Geekworm Cooling Fan Expansion Board (X728-A1) for X728 & Raspberry Pi 4 Model B/ 3B+/ 3B/ 2B - Geekworm 11mm Thickness Embedded Heatsink (P165-B) for Raspberry Pi 4, Armor Aluminum Radiator Compatible with Raspberry Pi 4 Model B Computer and Pi 4 Expansion Board Support POE Extension --- ## 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.co.uk/products/371701206-geekworm-for-raspberry-pi-ups-x728-max-5-1v-6a](https://www.desertcart.co.uk/products/371701206-geekworm-for-raspberry-pi-ups-x728-max-5-1v-6a) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
