If you have other questions, please let us know, thank you. **Q: I'm a little confused about which chemistry this bms is for. it says 18650 in some places and lifep. does it work with lifepo4 prismatic cells?** A: They honestly shouldn't specify 18650, as that is simply a form factor most notably used for Li-Ion, however it's possible that an 18650 cell could have LifePo4 chemistry. With that said, this model bms is a LiFePo4 BMS used for 3.2V Nominal, 3.7V charging profile LiFePo4 battery cells, most commonly found in larger form factors such as Prismatic, 32650, 32700, etc form factors. However even within those form factors, they are not exclusively used for LiFePo4, so it's most important to look at the nominal and charging profiles of your lithium batteries chemistry and match that to your bms. **Q: Will this work with LifePo4 32650 6000ma 12.4v?** A: Ending voltage should be 14.4 when fully charged, or 4 lifepo4 cells in series **Q: Will this BMS work for solar applications to charge a 280ah battery pack at 12v?** A: lifepo4 4s bms can be working for lifepo4 4s battery pack . both battery type and strings should be matched. as for the current , please specify the battery load W and the limited current then we can do a calculation. ## Frequently Bought Together - DALY Smart BMS 4S 12V 100A LiFePO4 PCB Protection Board with Balance Leads, Wires 3.2V Battery Protection Module BMS for 18650 Battery Pack 12V with UART(Smart BMS,100A) - Daly 5A Active Equalizer 16S Active Balancer for Lifepo4 Li-ion LTO Battery Groups Capacitor Balancer - 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.com.ar/products/275738210-daly-smart-bms-4s-12v-100a-lifepo4-pcb-protection-board](https://www.desertcart.com.ar/products/275738210-daly-smart-bms-4s-12v-100a-lifepo4-pcb-protection-board) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-29*
