The battery itself works great. Just had to cut the leads and swap the -/+ ### ⭐⭐⭐⭐⭐ BMPRO RV Control Panel Battery *by A***R on February 13, 2024* The battery in the picture is the bad one out of my RV BMPRO Tablet Panel. I bought this new Amazon battery and it works. I carefully disconnected the wires out of the white male plug. I cut the wire on the old battery leaving plenty of wire, because there's no matching female plug. Clean the ends of the wires and mash them in the wire looms of the new one. Tape them and reassemble the BMPRO tablet. IT WORKS GREAT 👍There is a YouTube instruction video but no need to solder if you do it the way I instructed. I cleared the coated wires using a lighter because it is very tiny. ## Frequently Bought Together - YDL 3.7V 2500mAh 505573 Lipo Battery Rechargeable Lithium Polymer ion Battery Pack with PH2.0mm JST Connector - 10pcs Upgraded Tiny Whoop JST-PH 2.0 Male and Female Connector Cable for Battery JJRC H36 H67 Blade Inductrix E010 E013 - Liter energybattery 3.7V Lipo Battery 2500mAh Rechargeable Lithium ion Polymer Battery 306080 Lithium Polymer ion Battery with JST Connector --- ## 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.us/products/113210691-3-7v-2500mah-505573-lipo-battery-with-jst-ph2-0mm](https://www.desertcart.us/products/113210691-3-7v-2500mah-505573-lipo-battery-with-jst-ph2-0mm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-29*
