Keep the devices powered for a hours and seamlessly work after being plugged in. Very happy with this purchase. Review: Working product, no issues - Appropriately sized, used two so far and no issues. Would be nice if the wires were a bit longer, but nothing a little solder and heat shrink can’t fix! Happy with my purchase ## Features - Charging Method: The recommended charging current is 0.5A, the maximum is not more than 1A. The discharge current is recommended 0.5A, and the maximum is not more than 1A - Overcharge Protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged, form an overcharge protection - Over-discharge Protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect - Short Circuit Protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous high current, or the components are heated and damaged - Note: The battery overcurrent protection is not a panacea, do not continue to charge and discharge the current and voltage with a large current beyond the range, otherwise the protection board will be damaged and invalid ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CXNQ3ZR | | Amperage | 1.5 Amps | | Antenna Location | ESP32 Development Board Whose Plug is SH1.25-2, Electronic Devices, Mesh Node T114 | | Battery Capacity | 1000 Milliamp Hours | | Battery Cell Type | Lithium Polymer | | Battery Weight | 17.76 Grams | | Best Sellers Rank | #90,599 in Health & Household ( See Top 100 in Health & Household ) #39 in 3.7V Batteries | | Brand | MakerFocus | | Customer Reviews | 4.5 4.5 out of 5 stars (326) | | Item Dimensions | 1.77 x 0.98 x 0.39 inches | | Item Weight | 17.96 Grams | | Manufacturer | MakerFocus | | Model Number | 7PVE55471137TGQWO5E | | Number of Batteries | 4 Lithium Ion batteries required.

I think you can use the battery and run the Pico on a breadboard, if that is what you were thinking. The RP runs off of 3.3Volts, so it is close enough. If you want to be safe you can use a TP4056. They are cheap enough. **Q: Can this battery be safely charged with a TP4056?** A: Hi, yes, it could be charged by TP4056. **Q: Can I charge it with your charging board?** A: Hi friend, you can use it can be matched with ESP32 Development Board WIFI Kits for Arduino Nodemcu, you could see the picture 4 on the listing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for Meshtastic Heltec V3 in a 3d printed case *by B***Y on May 22, 2024* These are great for the meshtastic V3. Keep the devices powered for a hours and seamlessly work after being plugged in. Very happy with this purchase. ### ⭐⭐⭐⭐⭐ Working product, no issues *by J***Y on December 11, 2025* Appropriately sized, used two so far and no issues. Would be nice if the wires were a bit longer, but nothing a little solder and heat shrink can’t fix! Happy with my purchase ### ⭐⭐⭐⭐⭐ Excellent IoT batteries *by T***S on July 4, 2024* I purchased these for my Meshtastic builds. I am using them to power a variety of ESP32-S3 powered devices for Meshtastic. Nearly all are solar charged and with a small 2"x3" 60mw solar panel. The build quality has been excellent and on par with what I see from major hobby RC manufacturers. I have since purchased 3 more sets of different capacities for other projects. ## Frequently Bought Together - MakerFocus 4pcs 3.7V Lithium Rechargeable Battery JST1.25 Connector 2pin, 952540 3.7V 1000mAh Battery with Protection Board and Insulated Rubber Tape Compatible with ESP32 Development Board - 915MHz LoRa Antenna Indoor 3dBi Gain Omni SMA Male + IPEX Cable 2 Pcs - MakerFocus ESP32 LoRa V3 Development Board with 915 MHz Antenna Integrated WiFi Bluetooth SX1262 CP2102 0.96-inch OLED Display Type C for Meshtastic IoT Arduino Intelligent Scenes --- ## 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.gr/products/67140034-makerfocus-4pcs-3-7v-lithium-rechargeable-battery-jst1-25-connector](https://www.desertcart.gr/products/67140034-makerfocus-4pcs-3-7v-lithium-rechargeable-battery-jst1-25-connector) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-22*
