When I received it, I tested it when I received it and it worked that one time fine, it powered my wireless iPhone charger. I did have it in my possession for about a week before I installed it into my 3d printed part at which time it did not work. All 3v and 5v connectors on the board shows 2.2 volts. Batteries are full, and tested four different charged batteries. The connectors to the USB-C connector shows 0 volts. I'm buying another one in case it was me that damaged it electronically, but if the new one doesn't actually work, I will be returning both. Review: No problems with this battery shield / mount.

When unplugging the charging cable from the battery pack from both the usb powered option and the 5v. **Q: What is the inside length of the battery housing? I want to use a protected 18650 cell with a 68.9mm length.** A: Hi friend, the 68.9mm is too long for the housing. **Q: Can someone clearly explain how this device works and its features? The instructions/manual is garbage and impossible to understand. Thank you.** A: Slide -Switch appears to have the following use: My V8 (dual-cell) unit has the slide switch (not labeled) and the push-button. Orient the board so you can see LED's and read stencil graphics, then switch is on the bottom-left of card. (a) slide-switch LEFT ("position closest to the short-edge of the board") == AUTO power-down mode == unit will turn-off when there is nothing taking power from the USB port. (b) slide-switch RIGHT ("position further from the short-edge of the board") == MANUAL == unit will remain ON until turned off or batteries too low. My unit does not auto-power up, but a single press of the button turns it ON, and double-press of the button turns it OFF. Triple-pressing the button only glitches the power off/on and does not affect the LED's unlike what someone answered here. **Q: can i hook a batterie bank to this to give this power? and dose it work with out the cells in it if i just have a batterie bank hooked to it?** A: Treat this module as a standalone power pack. You need two 18650 batteries. Interestingly, Amazon sells some flashlights that include the batteries and a charger. It's a great investment. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked for a minute, but not when installed. *by T***R on April 24, 2025* I'm mostly writing this review to document the date of which I put this into operation.

This is WAY better than a lot of DC/DC boost converters you can buy out there. Here's the 'meh': There are a set of LEDs on the bottom. For low current, battery powered devices, this is wasteful and consumes power for no benefit. They are easy enough to remove once you have the device operating properly. The device does not automatically turn when a battery is inserted. You must press the "enable" button once to turn it on. Here's the bad: There is an auto-sense that detects when there is no power being consumed and shuts the unit off. The definition of "no power being consumed" means less than 90mA, which is really quite a lot if you are using this device for a low-power microcontroller design. After about 30 to 35 seconds of "no-load" (<90mA) the unit will shut itself off. They provided a switch to "disable" the auto-sense, but this works by placing a fixed 90mA load on the unit to insure that there is always load above the shutoff threshold. For a long-lived battery device this is unacceptable as 90mA is more than my target design consumes and would drain the battery very quickly. This is a very poor, inefficient solution to the problem and not very good engineering. There is a solution to this, but it is a little hacky and requires cooperation with your target device. I added an external circuit (a single 2N7000 and a control line) to emulate a button press on the "enable" button every 20 seconds or so. When my system is running, I have to make sure that this circuit gets activated (pull the enable pin on the switch low for about a tenth of a second) every 20 seconds. This appears to reset the "no-load" timer and you get another 30-35 seconds. Do this every 20 seconds or so and the unit will run indefinitely at very light loads (my specific design consumes about 2mA nominally). You can't do it too fast as two quick presses of the enable button are what signals the device to shut off. I gave the unit 4 stars because the DC/DC converters are so darned efficient. If I had not been able to do the button-press emulation trick to keep the unit running under light load it would have gotten one star. I hope this helps anyone trying to use this DIYMORE battery shield for very low power designs. It you have the knowledge and provisions to tickle it appropriately it can work well, and be very efficient. If not, then the fixed load, or auto-shutoff might make it tricky to use effectively and efficiently. ## Frequently Bought Together - diymore Li-ion Battery V3 Shield 1 Holder 3V/1A 5V/2A USB Power Bank Battery Charging Module 1865O Battery Holder - 2pcs 1￵￵8￵6￵50 Rechar￵ge￵abl￵e Batter￵￵y,Using The 18650 Rechargeable Battery Charger (Does not Include The 18650 Battery Charger) (2pcs Button Top Batter￵￵y) - FORIOT 1865O Battery Holder Li-ion Battery with Dual Compartment Support Micro USB 5V/3A 3V/1A V8 Battery Shield --- ## 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.th/products/171448219-diymore-li-ion-battery-v3-shield-1-holder-3v-1a](https://www.desertcart.co.th/products/171448219-diymore-li-ion-battery-v3-shield-1-holder-3v-1a) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
