It is the chemistry. These will work with 3 rechargeable Lithium Ion or Lithium Polymer batteries (3.7V nominal, 4.2V totally charged) in series. I am using it with 12 cells of 21700 batteries in a 3S4P configuration. A pack of 3 AA or AAA Li-Ion or Li-Po batteries should work just fine. **Q: What is the output voltage and amperage from P+ and P-?** A: Specifications: 3 strings: 3 18650 batteries or polymer lithium batteries in series Polymer battery rated voltage: 10.8V Rated voltage of 18650 or 3.7V lithium battery: 11.1V After the lithium battery is fully charged, the voltage is 12.6V. Maximum discharge current limit: 10A Overcharge voltage range: 4.25-4.35v±0.05v Over-discharge voltage range: 2.3-3.0v±0.05v Maximum working current: 5-8A Maximum instantaneous current: 9-10A Quiescent current: less than 6uA Internal resistance: less than 60mΩ Working temperature: -40---+50 °C Storage conditions: -40-- +80 ° C Effective life: more than 30,000 hours **Q: Is there a minimum output to keep these alive? my application only draws about 60ma. some bms units require more.** A: I drew 40 mA, and it shut off to protect the batteries exactly as it was supposed to. ## Frequently Bought Together - Comidox 3S 12V 10A 18650 Lithium Battery Protection Board BMS Li-ion Charger Protection Module Anti-Overcharge/Over-Discharge/Over-Current/Short Circuit 3Pcs - DIYhz Push Button Switch, Self-Locking Mini Switches Latching 10mm Round DC24V 0.5A Black Cap 5PCS - DIYhz GX12 2 Pins Panel Metal Mount Circular Metal Aviation Connector Adapter Male Female Plug Socket with Waterproof Cap (5 Pcs) --- ## 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/342908041-comidox-3s-12v-10a-18650-lithium-battery-protection-board-bms](https://www.desertcart.com.ar/products/342908041-comidox-3s-12v-10a-18650-lithium-battery-protection-board-bms) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
