Re: Lipo Battery Help + Solar Charging

You have made a couple of simple mistakes that I will help clear up. 1) Your iCharger 4010 Duo is a DC charger , meaning it needs a DC source to use. I am looking at the specifications here .. https://www.progressiverc.com/icharger-4010duo.html If it was a AC and DC charger you could plug it into a...

Re: Lipo Battery Help + Solar Charging

Adding Mean Well P.S. to the load will get very heavy. Remember, I'm not on a Motor Cycle or anything of the sort. I'm riding a recumbent Trike over 12,000KM with my daughter so I desperately need to keep the weight down. She is only able to tow about 30lbs (She'll be 10) and I can tow approx 100-12...

Re: Lipo Battery Help + Solar Charging

If cost is not a factor then there's better cells in larger capacities, like used large-EV cells (Nissan Leaf, Zero, etc). Cost is a HUGE issue for me. I am disabled and low income. :oops: I need to keep it as inexpensive as possible, but still be able to pack in as much mAh, for distance, as I pos...

Re: Upload Your Circuit Schematics & Requests Here...

Separate batteries will work for sure, but quite a bit of extra weight. The other way to do it would be to use a DC-DC converter that takes your bike pack and drops it to 12v. This will weigh less and cost less. Here is an example: https://www.ebay.com/itm/DC-DC-Buck-Converter-Step-Down-Power-Suppl...

Re: Lipo Battery Help + Solar Charging

Like many when they became available, I have used big capacity bricks to limit the connections in battery assembly. I have abandoned them after realizing that they have serious downsides. The lower C rate of them is because those large cells are quick to overheat, and long to shed that heat, even w...

Re: Lipo Battery Help + Solar Charging

Hello everyone. A couple years ago I purchased a used Recumbent Trike (WizWheelz Zoomer - Pre-TerraTrike). This trike came with a BMC V3 motor in the rear 26" wheel. Attached to it is a 12 x 4110 MOSFET Extreme Modder Controller LYEN Edition and a Cycle Analyst V2.4. With the trike came 8 Turnigy 5...

Re: Lipo Battery Help + Solar Charging

4110 mosfets in a Lyen controller can handle 24s RC lipo. We upgrade them 12 fet Lyen controllers to feed 10kw with 84v nominal RC lipo. So, no problem with a 12s battery. Most likely it is programmable and, if you have the programming cable, you should set the new LVC. Your actual battery assembly...

Re: Upload Your Circuit Schematics & Requests Here...

Thanks. The trike does have a motor, but the battery setup is much different. The BMC V3 Motor runs off 8 lipo batteries running in Parallel & Series to total 37V (Being upgraded to 44.4V soon) which is more than the 12V needed. The idea behind these batteries is that I should only need to charge it...

Re: Lipo Battery Help + Solar Charging

I had to edit my original post... Realized a typo. The batteries I was using were: 8 x Turnigy 5000mAh 5S 20C - 30C Lipo Pack. I had 2 sets of 4. 1 set running in parallel to give me 18.5v 20,000mah. I then have a second set exactly the same. these two are then linked together in series giving me a ...

Re: Lipo Battery Help + Solar Charging

As for the Solar portion of this. I have the following Schematic that I designed. I used 2 batteries in the schematic (even though there will be more) as it seemed like a better idea at the time, but found out it would weigh more and I would prefer less weight (The MultiStar are also less expensive)...

Re: Upload Your Circuit Schematics & Requests Here...

Just a little schematic I threw together. I am open to "NICE" criticism, ideas, or suggestions. I am in no way knowledgeable in this field. I actually had to learn all of this as I created the schematic. I would Love to hear all feedback, except nasty messages... I own a WhizWheelz Zoomer (Pre Terra...
