Unsafe. *by R***M on February 17, 2025* The entire point of a multi-cell BMS is to have balance leads to charge each cell evenly. You should never charge multiple Li-Ion batteries in series without balance leads. t's not if they will, it's they will, it's when they will go Chernobyl on you. Don't buy these. I'm returning mine. unsafe. ### ⭐⭐⭐⭐ Worked perfectly to charge my 3S1P battery pack *by J***F on April 2, 2024* This is a review of a 2x USB-C 3S 1A 18650 battery charger board.I've been looking for a way to charge a 3S1P battery (in my case, a battery for an Elecraft KX2) which would let me leave my bulky brick charger at home. Now I'm able to carry this tiny board with me all the time and use it with the USB charger I always have with me - a huge win. I ended up sticking it in transparent heat shrink tubing to protect it while still being able to see the status LEDs, and I soldered on a pigtail which matches the barrel plug of my battery.I'm deducting one star because despite having a USB-C input, it can't use a USB-C power source. It doesn't seem to have a 5V PD trigger, so you end up needing to feed it with a USB-A to USB-C cable (or I suppose anything else that's only 5V).Pros:* VERY small* Charged my battery successfully* Put out a nice, slow charge to not stress out the battery* Able to detect a full battery (i.e. it doesn't keep pushing current after the battery is charged)Cons:* Requires a 5V source (i.e. you can't use a USB-C to USB-C cable, but you can use USB-A to USB-C) ## Frequently Bought Together - AITIAO 2PCS Type-C USB 2S 2A Boost Converter 8.4V 12.6V 16.8V Step-Up Power Module LiPo Polymer Lithium Battery Charging Protection Board - ALLECIN SN74HC595N 8-Bit Shift Registers with 3-State Output Registers DIP-16 SN74HC595 74HC595 Shift Register (Pack of 30pcs) - 15Pcs 5V 1A TP4056 Charging Module Micro USB 18650 Lithium Battery Charger Board with Protection… --- ## 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.hk/products/539165770-2pcs-type-c-usb-2s-2a-boost-converter-8-4v](https://www.desertcart.hk/products/539165770-2pcs-type-c-usb-2s-2a-boost-converter-8-4v) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-04*
