Hi, I was doing a research on a battery pack for UDOO x86 but I didn't find something useful so I thought about making my own one, the battery will be a DIY 4 cell 18650 3.7 V 9900 mAh rechargble Li-ion batteries attached in parallel and protected with this BMS (https://fr.aliexpress.com/store/pro...rd-For-4-Packs-18650/1523130_32623867436.html) for stabilazing the voltage to my UDOO I'll use this a 5A DC-DC-Step-Down-Adjustable-Power-Supply-Module for a stable 12V, and for charging I'll use a DC-DC 2 V-24 V to 5/9/12/28 V Boost Step-Up Power Module Micro USB 2A. what do u think about it ? Thanks.
No. Not that easy. I'd suggest to study and understand more first. Few hints: understand what are battery balancer, Li-Ion charging profile, Power Path mgmt, backflow prevention, no load shutdown, etc.
