I am not sure about recharge time. I just plug in wired power and have never paid any attention to how long it takes to charge. It is usually ready to go when I want to take Maestro untethered.
Many factors will affect charge time; a USB 2 port has a lesser charge budget than a USB 3 port. Then that budget may be shared if an external USB hub is used. Then some external USB hubs (StarTech ST4300USBMS) have external 12V connections that will supply maximum USB3 budget to each connected port.
YMMV could have been my only reply.
My battery did not charge when connected to the StarTech without external power (USB Hard drive took all the budget) but charged (don't know how long) when connected to a front panel USB 2 port.
I received the Maestro today- good work guys!!!
I do have a question or two on the battery. I have two Mojix 10400 mAh batteries. I first charged them outside of the Maestro. During testing I only got about 1 hour of battery life.
1) Is there any way of determining the state of the battery? The battery symbol does not change as its discharged. it. I ran it today for about an hour and started getting flashing LED lights and strange behavior from the Maestro at which time I returned it to the wall wart and it recovered.
2.)I only have one usb connector in the battery bay of the Maestro. I plug that into the 2.5A output of the battery. Will it charge through that connection? It appears to have a mico B connector that is labeled "In". That is the connector to charge the battery externally.
Thanks for all your help and such a great product!
The battery issue is very complicated - so I will just gloss over some things.
The Mogix battery should last about 4 hours from full charge. There is a button on the side of the battery which when you push it lights up to 4 LED indicating the state of charge. Please make sure you fully charge it before you use the battery.
Maestro were shipped without an internal micro-USB charging cable so the one USB A cable that you plug into is to power the Maestro NOT Charge the battery. You currently need to use an external USB Charger to Charge the Battery. Flex will likely issue an official explanation.
The Alpha Team has been experimenting with a number of different batteries. What we are finding is that there is significant quality/performance variations between the different batteries of the same model from the same manufacturer. So much so that the same battery model works well for one Maestro but a different battery of the same model fails in the same Maestro. Our experiments are currently ongoing.
in the Interim until Flex makes an official recommendation, several of us have had more reliable results using the 12,000 mAh Polanfo
Having tested both, I personally would recommend the Polanfo over the Mogix which failed consistently in my Maestro
These experiments took a significant amount of Alpha testing time until we determined that it was the poor quality control of the battery rather than the Maestro which was the problem.
6 18650 cells should fit in there and Panasonic makes a 3400MAH cell
something like this
but i think we need 2.1 amps?
I have an abundance of 18650's, and could build up power modules with them, but am thinking it might be better to have a couple of lead/acid motorcycle batteries (with carrying straps) and just plug into the coaxial 12V connector on back. Using a PowerPole multi-outlet, I could switch back and forth with BUFFERED power while switching. I'll have to think this over while waiting.
This is ALMOST a deal-breaker. I might change my mind a few times before I'm invoiced.
