Hi folks, I’m in the process of turning an RB2011 (barebones board, 3D printing a case and adding antennas etc) Into a replacement for my long-standing 2*mAP ‘Travel Router’ setup. Since I’m printing my own case, and power switching from car to hotel etc has always been a pain point, I figured internal batteries with 4-5hr life would be fantastic. 4-5s of Lipo would fit the job nicely, but then how to charge them? Got the idea from an awesome ‘UPS’ board that I use on my raspberry pi’s, but 5v is a lot simpler to step up to from 3.7v, than 12v is :) After a lot of googling, I’m not finding much in the way of BMS’s that support balance charging and supplying power to a load other than going for an expensive (and bulky) solar charge controller. I was wondering if anyone has dealt with something similar before? Thanks, Damien -- Damien Gardner Jnr VK2TDG. Dip EE.
