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/ASL4551BT: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 The same great Powerhouse LiFePo4 performance now with added in-built **Bluetooth battery monitoring**. Pair your battery with your phone and stay up to date with how your battery is charging and discharging as you use it. It offers live stats and historical data via an iOS or Android based app. This 12V 20Ah lithium battery (LiFePO4 chemistry) is compatible in size with traditional 26Ah SLA batteries, but with all the benefits of cutting edge lithium technology. LiFePO4 batteries offer longer service life than traditional lead acid batteries, plus weigh less than HALF as much as SLA batteries. LiFePO4 also provides more usable life per cycle, allowing for longer run times by holding a higher voltage until capacity is almost exhausted. These batteries will also maintain 80-90% charge when in storage - far higher than their lead acid counterparts. The latest generation in maintenance free batteries is here!Each battery is fitted with an internal battery management system to provide safe charging and discharging at all times. This system provides internal short circuit, over temperature and under/over voltage cut off. Can be wired in series and/or parallel. When used in series each battery will need to be discharged to cut off before connecting so that all cells are all balanced. **Factory supplied at 30% charge for safety compliance. Must be charged fully before use.** #### Features - Internal battery management system for safe charging and discharging. - Drop in replacement for standard lead acid 20Ah batteries - Half the weight of traditional lead acid batteries. - Less discharge when in storage compared with traditional lead acid batteries. - Longer service life compared to lead acid. - Longer run time compared to lead acid. **About the Bluetooth monitoring App.** The *Powerhouse* battery monitoring app is currently in development, however in the mean time customers can utilise the XiaoXiangElectric battery monitor app available on the GooglePlay and Apple App stores at the links below:[iOS App Store](https://apps.apple.com/au/app/xiaoxiangelectric/id1576622653)Android Devices ### Specifications - Battery Module - Nominal Voltage: 12.8V - Capacity: 20Ah - Charging Voltage: 14.8V max, (Recommended 14.2V) - Discharging Voltage: 8.8V max, (Recommended 10.8V) - Charging Current: 20A max, (Recommended 4A) - Max Constant Discharge: 20A - Dimensions: 181L x 77W x 167Hmm - Overall Weight: 2kg - Terminal Type: M5 - Connection: 12-48V max 4 in series, no limit in parallel. - Note: When used in series each battery will need to be discharged to cut off before connecting so that all cells are all balanced. - Case Material: ABS - Case IP Rating: IP65 - Certification: CB/CE - Shipping Class: UN3480, Class 9 ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/A/S/ASL4551BT-1.jpg)
