We are looking for someone to work with us on a portable 14S Li Ion battery pack/UPS with DC and AC out managed using ESP8266/Arduino. Phase 1) System design (the scope of this initial request). Make use of a schematic tool such as [login to view URL] [login to view URL] [login to view URL] which we can collaborate on to arrive at a workable BOM. Use mostly off the shelf modules/components e.g. for the inverter. If possible, simulate. Outline here: [login to view URL] Phase 2) Prototype, code ESP8266 and test. Phase 3) Refine design/custom PCBs, look to build a cost effective balance charger rather than using a BMS, support for PV input, look at inverter options with Synch/PLL to act as a UPS and ability to connect these units in parallel. Phase 4) Hardware design
