Pezman Posted April 22, 2017 Share Posted April 22, 2017 I think you can compare both solutions in that both accomplish the same primary goal of extended range. These solutions may differ in how seamless they are, how convenient they are, and how much modification is required to the Mini. Personally I'm intrigued by both of your plans and I wait to see the results so I can weigh the pros and cons of both options. As a side question: Could a quick and dirty option simply be to string two battery packs together in Parallel somehow be an option? Or have them connected in series with a toggle to switch to the reserve battery? Perhaps you could string many packs together and get mega range (backpack loaded for 100km rides - lol - better hope it does catch on fire) Quote Link to comment Share on other sites More sharing options...

So you can't really make a compare between our solutions. I wasn't exactly making a comparison, I was getting involved in the general "extending the range" conversation and sharing some alternative solutions with other forum members. I think it's funny that you keep getting defensive when someone makes a suggestion that isn't exactly the same as yours.

But it's not the subject of this topic and someone which is not interested in using an external battery, will certainly not read this topic and will not discover other solution. Maybe it would be useful to open a new topic like "many solutions to extend your distance range"?

I'm sorry, I'm confused.. I thought the subject here is actual an eternal battery, I checked 3 times and yup that's what it says. Eternal battery by definition would be outside the Mini and probably in a backpack.

Your external battery powers the MiniPro while in use. My external battery charges the MiniPro while resting. They're both DIY external batteries designed to extend the range of the vehicle. So I don't think there's reason to get defensive or suggest that I take my alternative version to another thread. Quote Link to comment Share on other sites More sharing options...

Pezman Posted April 22, 2017 Share Posted April 22, 2017 Fair enough. Lets get back to discussing potential solutions. I was wondering if solar panels could generate enough power to trickle back to the Mini. Would there be enough return to actually extended the range? 1 Quote Link to comment Share on other sites More sharing options...
kasenutty Posted April 22, 2017 Share Posted April 22, 2017 My charger gives me enough extra range. It's a legit option for a North American mini owner who needs 5 more miles. Like me. 1 Quote Link to comment Share on other sites More sharing options...

I was wondering if solar panels could generate enough power to trickle back to the Mini. Would there be enough return to actually extended the range? I like the idea of this. I have charged my MiniPro 100% by solar since I bought it. I have 200 watts of panels outside going into a 300 amp hour battery bank in my office that I use for charging my e-bikes, skateboards and the minipro as well as all my other gadgets. On bright days I run my laptop from it all day. But the panels are too large to carry by MiniPro. However, i have a few folding portable panels that easily fit in a small backpack. One of them puts out an average of 50 watts in strong sun. It would be possible to step the voltage up to 63v and put some charge into the MiniPro if one were to rest in a park or somewhere in the sun for a couple of hours. But it would take all day (maybe two days) to fully charge the battery that way from low. There are larger folding panels though that produce more watts. I have a 100w Renogy folding panel; it's a DIY of two 50w panels in a briefcase configuration and is still too large to carry on a MiniPro for a long distance. But with it plugged into a battery and an invertor I get a portable (by car) 110v supply to power my things when away from the grid.

MetricUSA Posted April 26, 2017 Share Posted April 26, 2017 Well, I blew something and my first idea was to directly parallel the mini battery anyways, now I have to tear into it sooner, like now... We'll see what I did... And I already have 100 w panels just for on the go trailer charging and booster board...So got to see this through!

Yeah I don't feel comfortable about connecting another battery to the charging port and running it in parallel. I prefer to stop, take a break and top the battery up. 2 Quote Link to comment Share on other sites More sharing options...
MetricUSA Posted May 19, 2017 Share Posted May 19, 2017 (edited) Found blown fuse...F3 and a kinked thick + battery wire... Don't know amperage to use assuming 3 amp... Would like to know what the white and yellow wires from plug are doing.... Oh my charger female plug on my Asain mini popped out on my this morning! Now how that happened? Now I am going to have to open that battery, too! Could be loose nut in pack! Edited May 19, 2017 by MetricUSA Quote Link to comment Share on other sites More sharing options...

During my test I have measured more than 4A while using external battery linked to charging plug and BMS is still OK. 12 minutes ago, MetricUSA said: Would like to know what the white and yellow wires from plug are doing.... Me too, I have supposed they are the link between BMS and mother board, maybe that's will explain if the battery is recognize by the motherboard or not.

The Ninebot Mini battery is a lot cheaper than the MiniPro one. I'm just going with the portable charger option because I already have all the parts I need and won't have to spend any money. I agree. Where do they sell Mini batteries? I'm in USA, so that's a consideration. ➰ Quote Link to comment Share on other sites More sharing options...
RooEUC Posted July 27, 2017 Share Posted July 27, 2017 @MetricUSA Before taking the battery apart, how did you know something was blown? Was the battery no longer accepting a charge? Quote Link to comment Share on other sites More sharing options...

smallexis Posted July 28, 2017 Author Share Posted July 28, 2017 My best solution (maybe somebody could have a better one but I have not read it yet) is here : External battery is directly linked to the power wire of the motherboard, that avoid to have damage on internal battery due to high amper value and that allow to use the max capacity of the external battery. 1 Quote Link to comment Share on other sites More sharing options...

I think this is a good way to do it. Plugging an external battery into the charging port may damage the MiniPro's battery if it's at a low level of charge and the external battery is at a high level of charge. @MetricUSA did your Minipro stop taking a charge after the fuse blew in the above situation? And have you managed to repair it? 1 Quote Link to comment Share on other sites More sharing options...
MetricUSA Posted July 30, 2017 Share Posted July 30, 2017 (edited) OK been awhile, first a solution to internal blown fuse... And I should had run wire to parallel the internal battery while I had it open. The only good spot to run it out is where the fuse now sits.... And now I need help for a hitch, the strap is not cutting it, good for back up, but definitely need a hitch... Seriously, a 50 watt (or two) would have done the trick...
