Bluetooth speaker Dash cam Bark collar for dog Keyboard and mouse Review: Good quality battery for Dell Axim X5 1X390 battery - Bought to refurbish the original 1X390 battery for a Dell Axim X5. The old Lithium cell was not holding a charge. It is not a straight swap and requires opening up the old battery with tools and removing the charge board/cables from this one to wire directly to the Axims battery circuit. This just fits in the space of the old one - and then glue the battery case halves back together. Works well and holds charge for long time. Review: EEMB Lithium Polymer battery for an educational electronics kit. - The EEMB Lithium Polymer battery works perfectly. It was easy to install and to charge. ## Features - Attention: Confirm 3 Factors Before Purchase - This 3.7V 1100mAh LiPo is NOT universal.

This one may be too big. You need to measure the space first. **Q: What is the connector? i bought this and the jst connector does not fit the jst connectors i have, so what is that connector ???** A: It is JST PH (2mm pitch). There is 12 types of JST connectors listed on Wiki. **Q: Can i cut the connection off so i can solder it to a circuit? if so which do i cut first?** A: Cut one connection at a time, do NOT cut through both at the same time… if you short them together they may weld together and then proceed to burn. If you do cause a fire don’t use water, use sand, dry soil to smother the battery. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality battery for Dell Axim X5 1X390 battery *by J***N on 11 June 2026* Bought to refurbish the original 1X390 battery for a Dell Axim X5.

It was easy to install and to charge. ### ⭐⭐⭐⭐⭐ Great replacement battery. *by A***D on 27 January 2026* Great replacement of the battery in an old car hands free Bluetooth speaker found in storage after years which was no longer charging or powering up. Had to snip away the wire connector plug to allow for direct soldering to circuit board but this was straight forward using snips. The battery arrived precharged at 70% level confirmed once connected to Bluetooth and offers a higher maH to the OEM battery replaced. Size and fit are great as expected. ## Frequently Bought Together - EEMB Lithium Polymer Battery 3.7V 1100mAh 603449 Lipo Rechargeable Battery with Wire JST 2.0mm Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase - HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions - elechawk 10pcs Upgraded Tiny Whoop JST-PH 2.0 Male and Female Connector Cable for Battery JJRC H36 H67 Blade Inductrix E010 E013 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/244034199-eemb-3-7v-1100mah-603449-lipo-battery-with-jst-plug](https://www.desertcart.us/products/244034199-eemb-3-7v-1100mah-603449-lipo-battery-with-jst-plug) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-01*
