Lipo packs for routerboards? :)
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.

Hi Damien, Aliexpress might be the go here - I've done a few projects utilising Lipos before and you'll likely be able to find a charging circuit that matches your requirements here. I did a quick search that might help point you in the right direction, some have adjustable output voltages others are fixed: https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20190911170200&SearchText=12v++lipo+battery+charge+circuit&switch_new_app=y Cheers, Andrew Cox -----Original Message----- From: Public <public-bounces@talk.mikrotik.com.au> On Behalf Of Damien Gardner Jnr Sent: Sunday, 8 September 2019 8:26 PM To: MikroTik Australia Public List <public@talk.mikrotik.com.au> Subject: [MT-AU Public] Lipo packs for routerboards? :) 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.

These work nicely with Microtik slightly off subject because it's used for backup but does work nicely. It powers a RB3011 for longer then 10 hours (I stopped timing after that and turned the power back on) https://powershield.com.au/get-wifi-plugging-dc-mini-ups/ On 12/9/19 11:10 am, Mike Everest wrote:

Thanks Guys, I've ended up with a DFRobot PI UPS Hat (DFR0494), a Pololu 5v->12V DC-DC Step-up convertor (POLOLU-2577), and a 6AH Lipo. On testing the RB2011, it only pulls ~200mA at 12V, so there's plenty of headroom left. Also means I can normally run the router off a normal 5V 1-2A USB supply, so it'll be happy in the car :) Thats all theory right now, should have it up and running tonight or tomorrow night :) The nice thing with the UPS Hat is it also includes the battery fuel gauge which is a nice touch!
