Review: Works so far will report back - Works and bought for the size. You can fit this and a 14s3p in the new mini harbor freight ammo box. Xt90 discharge xt60 charge Molicel cells 21700 4200mah Review: Updated - Original Review: Works perfect for my 7S4P golf cart battery build. The instructions are decent but could be confusing if you don’t understand basic BMS technology. The App works fine for me too. It is not very intuitive and I’m still trying to understand a few features. There is not a lot of information online or on YouTube that clearly explains it. But it works on my IPhone 16 and has been solid so far. The quality of the hardware seems to be excellent. Updated Review: I have used this BMS for several months now. I am downgrading my review because the passive balancing is fairly useless. I have tried many different parameter settings with no success. I have searched the web for better info on how to improve it. I’ll update the review again if I ever find a way to get it working. ## Features - 【DALY BMS】Overcharge Protection; Overdischarge Protection; Overcurrent Protection; Short circuit Protection; Temperature Protection;Waterproof Protection. - 【Support Parallel Connection】Integrated parallel module to avoid large current impacts when battery Pack(s are connected inparallel. - 【Making Load Easy To Start】High-power pre-charging can effectively avoid false triggering of protection caused by high current at startup moment and unsuccessful power-ups. - 【Effective Balance】100mA passive balancing helpsextend lithium battery life. - 【Quality Guarantee】We provide 24-hour one-on-one customer service and technical support.If you have any questions,please feel free to contact us.--- ISO/ FCC/ RoHS/ PSE/ CE APPROVED ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DFXXHNMG | | Best Sellers Rank | #389,742 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,701 in Power Converters | | Brand | DALY | | Customer Reviews | 4.3 out of 5 stars 7 Reviews | | Item Dimensions | 4.84 x 2.56 x 0.55 inches | | Item dimensions L x W x H | 4.84 x 2.56 x 0.55 inches | | Manufacturer | Dongguan Daly Electronics Co., Ltd | | UPC | 753252846215 | ## Product Details - **Brand:** DALY - **Item dimensions L x W x H:** 4.84 x 2.56 x 0.55 inches - **UPC:** 753252846215 ## Images ![DALY Smart BMS with Bluetooth Module Li-ion 3S-20S 12V-72V 40A-500A Battery Protection Board for Li-ion Battery Pack(Li-ion 7S 24V 40A+BT Module) - Image 1](https://m.media-amazon.com/images/I/61lDmhmjmiL.jpg) ![DALY Smart BMS with Bluetooth Module Li-ion 3S-20S 12V-72V 40A-500A Battery Protection Board for Li-ion Battery Pack(Li-ion 7S 24V 40A+BT Module) - Image 2](https://m.media-amazon.com/images/I/718dA73pWaL.jpg) ![DALY Smart BMS with Bluetooth Module Li-ion 3S-20S 12V-72V 40A-500A Battery Protection Board for Li-ion Battery Pack(Li-ion 7S 24V 40A+BT Module) - Image 3](https://m.media-amazon.com/images/I/81OfD6TtxqL.jpg) ![DALY Smart BMS with Bluetooth Module Li-ion 3S-20S 12V-72V 40A-500A Battery Protection Board for Li-ion Battery Pack(Li-ion 7S 24V 40A+BT Module) - Image 4](https://m.media-amazon.com/images/I/717xBLcXLtL.jpg) ![DALY Smart BMS with Bluetooth Module Li-ion 3S-20S 12V-72V 40A-500A Battery Protection Board for Li-ion Battery Pack(Li-ion 7S 24V 40A+BT Module) - Image 5](https://m.media-amazon.com/images/I/71FD7vyRhhL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works so far will report back *by J***E on May 6, 2026* Works and bought for the size.
