We only sell Daly brand BMS units because of their ongoing commitment to the providing the highest quality, most robust, most reliable and efficient BMS units currently available (outside of OEM battery production). After reviewing Daly's designs, reliability, capabilities, production capacity, and attention to detail, it's no wonder why we stopped using other types of BMS units, and now only stock Daly for both custom battery packs and repairs.

Sense wires are always included with purchase of the BMS unit.

Common Port vs Separate Port

We only stock the 'common port' BMS units, which means that both the charger AND load (motor controller) are connected to the same wires on the BMS. The other type of BMS is 'separate port,' which means the charger and load are connected to a different set of wires on the BMS. While very common on e-bikes, separate port BMS units do not always allow for simultaneous charge & discharge, which is required in any solar EV application; in other words, if you're building a solar e-bike, you want to use a common port BMS to ensure your solar power is going directly to the battery AND motor controller with no interruptions. This way, even if your battery dies, your solar array can actually still power the e-bike if you have enough power coming in from the sun!



Product Description (provided by the manufacturer)

Daly Battery pack bms 10S 36V 15A 20A 20A 30A 40A 50A 60A BMS Used for 36v 10ah 35ah 60ah battery 60A continuous With balance function Model: DL10S (3.7V rated Li-ION Battery not for 3.2V Rated LiFePO4) common Version : common port for charge/discharge separate Version : separate port for charge/discharge We can customize any PCB from 1S to 30S lithium batteries with different current. If you don't know how to choose the common port or separate port bms, please contact us for free!Thanks for your support! ​ Highlight:For the same model, its charge current is less than discharge current because Daly PCBAs were updated to well protect customer battery. Any request, Please contact us. Daly: Jan 2020 1. Overview ◆DL10S 36V 15A 20A 30A 40A 50A 60A bms is used for 10series 36V battery pack. ◆We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc. ◆The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc. ◆According to the customer request we can develop PCM in different sizes and structures. ◆BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle serivce life time. 2. Advantage ◆Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan. ◆Strong load ability, constant discharge current 15A 20A 30A 40A 50A 60A , use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling. ◆IC itself has power balancing function. The circuit is simple and reliable. ◆Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load won’t affect the PCB and the battery.Temperature protection during charging and discharging. ◆Extreme low power consumption. The consumption of the whole device is less than 50uA. ◆PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.
