LIPO chemistry is the highest energy density chemistry around and due to that, you get nominal 3.7V at 4400mAh! > ⚠ Extra precautions need to be taken when handling Lithium Polymer batteries. [Our tips for LiPos can be found here.](https://core-electronics.com.au/guides/analogue-electronics/our-guide-for-using-lipo-batteries/) ## Pricing - **Price:** $28.50 (inc GST) — $25.91 AUD, exc GST - **Quantity discounts:** 5+ $24.62 (exc GST) · 20+ $22.02 (exc GST) · 100+ $18.14 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 47 today; more stock is typically available with a 30–40 day lead time. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE04380:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE04380:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description **\*LiPo batteries require special handling and use for safe operation. We recommend that you read our [tutorial on using LiPo batteries safely](https://core-electronics.com.au/guides/analogue-electronics/our-guide-for-using-lipo-batteries/) if you haven't worked with them before\*** This Lithium Polymer Ion based battery is a slim, lightweight battery that is perfect for a portable project! LIPO chemistry is the highest energy density chemistry around and due to that, you get nominal **3.7V at 4400mAh**! This battery comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins. Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries. This battery is terminated with a standard 2-pin JST-PH connector (that is with 2mm pin spacing).Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries. Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries, or you risk some damage to your battery. This battery includes built-in protection against over voltage, over current, and minimum voltage (all present under the yellow plastic at the top of the battery). **Note:** - The battery is rated for 2C continuous discharge, however, the wiring is only rated for 1A so be careful. - The JST connectors can also be quite fragile. While they stick in quite well, tugging on them can damage the connector. Check this tutorial from Sparkfun for the safe removal method. - You should also exercise caution when using these batteries in a wearable project, unless you are seasoned with LiPO operation you should stick with Coin Cell batteries. **Wire Handling Warning:** The battery wires and connector are delicate. Avoid pulling, bending, twisting, or repeatedly moving the wires, as this can damage the connection or battery. Handle the battery by its body only, and keep wire movement to a minimum during installation and use. ### Dimensions - 52x34x24mm ### Weight - 81g ### Features - 2C continuous discharge - Standard 2-pin JST-PH connector - Excellent long-term self-discharge rates (<8% per month) - Robust power source under extreme conditions (-10 to 50C) ### Documents - PCM Datasheet - MSDS ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/l/i/lipo-4400mah-2.jpg)
