Let's work together to make the large monomer power bank better!
I. Safety! Because
1. Battery cell: Uses a large monomer lithium power battery cell, with a continuous discharge current of 90Ah, so normal discharge can reach 270W. However, the actual power bank is only 22W, far less than the rated current of the battery cell, so the battery cell will not heat up during charging or discharging.
2. Structure: The internal battery cell has anti-collision cushioning, so the power bank falling will not damage the internal battery cell; the battery cell and the circuit board are isolated by a safe distance, preventing heat from the circuit board from affecting the battery cell.
II. Durable! Because
1. Battery cell: This type of battery can be charged and discharged over 1000 times without swelling. (V1.0 uses a lithium iron phosphate battery, theoretically capable of over 2000 charge-discharge cycles, which is safer, more stable, and non-explosive than ordinary lithium batteries)
III. Low cost! Less than 100 RMB. Because
1. Battery cell, this cell costs less than 30 RMB (Purchase link:https://mobile.yangkeduo.com/goods2.html?ps=aIArpsDnvJ)
2. Power bank mainboard, less than 30 RMB (Purchase link:https://item.taobao.com/item.htm?id=808265387106&mi_id=0000CuGfWxBZpmMY_-W0Z61j2jW3PRO_AsVhpDc-FD2LlPE&spm=tbpc.boughtlist.suborder_itemtitle.1.455a2e8dVt81lJ )
3. Printed parts, less than 10 RMB
4. Auxiliary materials: Electric soldering iron, solder wire, 2.5 square electrical wire, self-tapping screws, all within 10 RMB. The electric soldering iron can also be used long-term.
IV. Open-source editable SolidWorks files, which you can directly download and edit to match your needs
