Essentially you will be able to charge at whatever the full output is... since you're using the same mosfets. I've tested this personally on this unit, and similarly-priced models from other vendors. It's a shame, because I'm trying to use this with an alternator and I am starting to think BMS is not possible. I will have to get a charge management controller. **Q: It specifies charge voltage of 15v. can i use an 18v dc? will it regulate it for proper charging voltage and current? thanks.** A: Hello~ You cannot use an 18 v dc, it's higher than 15 v, and may cause damage to the protection. It means that the max charging voltage is 15 v. Hope this could help you, and thank you for your support! **Q: how to wire up the separate port BMS to solar charge controller? Is there diagram?** A: solar positive and battery positive go together on the battery and solar ground goes to battery charge ground on the bms **Q: Hello, each of my four 12v 12ah lifepo4 batteries already have individual internal bms protection. would adding this unit make any sense? thx** A: It depends on you, and this protection circuit board helps protecting battery pack from overcharging, over-discharging over-current and short circuit. and it is designed with equilibrium function to keep each cell in balance and good service life. ## Frequently Bought Together - 12V 100A 4Series BMS Protection Board with Balancing with Overcharge/Overdischarge/Overcurrent/Short Circuit Protection for LiFePO4 Battery Pack - DEWIN Pure Nickel Strip 99.6% Nickel, 1M 0.15 mm Soldering Tabs for High Capacity 18650 Lithium Battery Pack, Li-Po, NiMh and NiCd Battery Pack and Spot Welding --- ## 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.kr/products/47156062-12v-100a-4series-board-with-balancing-with-overcharge-overdischarge-overcurrent](https://www.desertcart.kr/products/47156062-12v-100a-4series-board-with-balancing-with-overcharge-overdischarge-overcurrent) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-10-24*
