Do not mix the good battery and poor battery to use. The internal resistance of battery capacity are closer will be better. Package included: 1x 13S 35A lithium Battery Protection Board with Balanced Review: good product, works perfectly - I stupidly shorted the battery terminals on my Addmotor M560 ebike, and of course the battery "bricked" and went dead instantly. I took the thing to a bike shop and they told me "sorry we don't fix batteries, talk to the manufacturer". I did, and was told that my battery was just slightly obsolete, I could send the battery to them for evaluation but if the BMS board was blown, they wouldn't ship it back to me but instead scrap it there and cause me to shell out $699 for a new battery pack. Ugh. SO I bought this nifty BMS board and with great care I opened the battery pack and replaced the bad BMS board with this one. Perfect, it worked as advertised and I saved myself $685 dollars! HIGHLY RECOMMENDED but don't try this if you aren't good with soldering and well versed in handling live power electronics.... These batteries can put out a LOT of energy if shorted, and easily become a firebomb on your kitchen table if mistreated!! Review: There isnt a way to turn off power - This BMS doesnt have provisions to install a power switch, and therefore the plug has voltage output all the time. During storage the BMS is consuming power **EDIT- after only a couple charges the "C" terminal on the circuit board has no connection, therefore i connected the charge wire to the "P" and its charging again, but know that this is a workaround ## Features - High-accuracy voltage detection circuit, fine workmanship and durable. - With Over-discharge protection, overcurrent protection, overcharge protection, temperature control protection function, safe and reliable. - The protection board is for 13 series cell Li-ion batteries, it can be used for 3.7V ternary batteries, manganese acid batteries and cobalt acid batteries. - It has balance function which would ensure each battery cell being fully charged at same time. - It is suitable for electric car, electric power assistant car, skateboard car, inverter, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KGTHL5H | | Best Sellers Rank | #220,294 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #884 in Power Converters | | Customer Reviews | 3.8 3.8 out of 5 stars (65) | | Date First Available | October 27, 2021 | | Item Weight | 1.83 ounces | | Item model number | ANMBEST_MD390 | | Manufacturer | ANMBEST | | Product Dimensions | 0.39 x 2.03 x 0.39 inches | ## Product Details - **Brand:** ANMBEST - **Color:** Silver + Green - **Item Weight:** 52 Grams - **Output Voltage:** 54.6 Volts - **Product Dimensions:** 0.39"D x 2.03"W x 0.39"H ## Images ![13S 48V 35A PCB BMS Protection Board Li-ion Lithium Battery Charger Lipo Cell Module with Balance for Battery Cell Pack - Image 1](https://m.media-amazon.com/images/I/618-rP5m1iL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good product, works perfectly *by G***D on August 13, 2024* I stupidly shorted the battery terminals on my Addmotor M560 ebike, and of course the battery "bricked" and went dead instantly.

During storage the BMS is consuming power **EDIT- after only a couple charges the "C" terminal on the circuit board has no connection, therefore i connected the charge wire to the "P" and its charging again, but know that this is a workaround ### ⭐⭐⭐⭐⭐ So far so good *by A***R on August 29, 2025* I have bought several of these. I just had one that I thought had an issue but upon further diagnosing it was unrelated and even though the battery caused the BMS to go into a fault it actually recovered. I'd call that a really good test verification that it does function properly. I haven't tested all features but do assume based on using these on many packs and not having any comebacks or issues that these are a good option. ## Frequently Bought Together - ANMBEST 13S 48V 35A PCB BMS Protection Board Li-ion Lithium Battery Charger Lipo Cell Module with Balance for Battery Cell Pack - 200mm(7.9in) Width PVC Heat Shrink Wrap Tube 18650 21700 26650 Lithium Battery DIY Battery Pack 3M(9.9ft) Length Blue - Nickel Strip 10m 0.15x8mm Nickel Tap for 18650 Cell Battery Pack Spot Welding 1Roll --- ## 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.co.uk/products/379954872-13s-48v-35a-pcb-bms-protection-board-li-ion-lithium](https://www.desertcart.co.uk/products/379954872-13s-48v-35a-pcb-bms-protection-board-li-ion-lithium) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
