It prevents overcharging and unnecessary battery drain through precise voltage thresholds and dynamic alternator monitoring, ensuring optimal battery health and longevity. Compact and lightweight, this USA-made device is essential for any professional seeking reliable, efficient power management on the go. ## Description Lithium Battery Isolation Manager ## Features - Under normal charging conditions, the BIM will connect for 15 minutes every 35 minutes. That means that the BIM will connect for 15 minutes, disconnect for 20 minutes, and repeat this cycle until the coach battery is charged. - If the coach battery resting voltage exceeds 13.4V than the BIM will disconnect. A resting voltage greater than 13.4V indicates a fully charged battery. Note that “resting voltage” means that no current is flowing to the coach battery. The BIM will disconnect if the alternator voltage exceeds 14.4V. This protects the coach battery from over charging. - The BIM will disconnect if the voltage difference between the alternator and the coach battery is less than 0.1V. If the voltage difference is too low, then there is a negligible charging current, and no need to connect to the coach battery. - The BIM will disconnect if the alternator voltage drops below 13.3V. If the alternator voltage is too low, than it cannot adequately charge the coach battery, so there is no reason to connect. - Made in the USA. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Precision Circuits | | Brand | Battle Born Batteries | | Package Dimensions | 16.4 x 10.6 x 6.6 cm; 249 g | | Item model number | BIMLIFEPO4 | | Manufacturer part number | BIMLIFEPO4 | | Item Weight | 249 g | ## Product Details - **Brand:** Battle Born Batteries - **Size:** normal - **Item weight:** 0.25 Kilograms - **Manufacturer:** Precision Circuits - **UPC:** 704751581626 ## Images ![Lithium Battery Isolation Manager - Image 1](https://m.media-amazon.com/images/I/41yNTpNBPfL.jpg) ## Questions & Answers **Q: Can it connect continuously like the Cyrix and others? It will take over twice as long to charge if it's disconnected so much of the time.** A: The purpose of this is to protect the alternator. If it was continously charging the alternator could overheat. **Q: What are the factors to consider when choosing either 160A model or 225A model? Thank you** A: 225A is rated for Lithium batteries. 160A is not. **Q: What gauge wire do I have to run between the house battery (lithium) to the isolate and then from the isolater to the car battery?** A: I ran 2 gauge wire up to the front so that you have the best bet of the coach batteries being able to start the engine when you tether them together. **Q: I assume this unit replaces the old mechanical bim 00-10021-000. the wiring appears the same, so i assume its also plug and play?** A: For the most part, yes. I used it to replace my auto charging and aux start relay in my BCC for my RV. This was needed to protect my alternator from overheating due to my upgraded lithium battery install on my coach. ## Frequently Bought Together - Lithium Battery Isolation Manager - 12.8V 460Ah Low Temp Cutoff LiFePO4 RV Battery, APP Monitoring, Built-in 250A BMS, Max. 3200W Load Power, 5880Wh Usable Energy, 5000+ Cycles Lithium Battery, Perfect for RV, Motorhomes and Off Grid - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing --- ## 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.tw/products/556621972-lithium-battery-isolation-manager](https://www.desertcart.tw/products/556621972-lithium-battery-isolation-manager) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-13*
