Hey, I was looking to source an inexpensive battery pack for a new robotics project. I’m looking for 12V (plus or minus 11V to 15V would be fine), and around 80-100Wh. Current continuous would be perhaps 5-10 Amps during the most intense usage. I’m definitely looking for something with Lifepo4 chemistry to be on the safer side in terms of fire / short circuit hazards, and an included BMS.
In the past, I used this exact pack: Customize LiFePO4 18650 Battery: 25.6V 3000 mAh (76.8Wh, 7A rate, 2Rx8) with PCB, UN Approved
It was solid, but I was hoping to cut the voltage in half, which would let me run some electronics directly without an additional 25V to 12V converter. But that company is rather pricey, and doesn’t have exactly the same pack in a 12V configuration.
I found these on Aliexpress which look quite solid, but I haven’t seen these sourceable in the United States directly.
Any thoughts? It looks like a solid design, but I haven’t seen such cells before.
