I have a few home built LED "Bottle" LED lights. I wrapped strips of LED's around plastic bottle in a spiral and run them at rated 12V +/-. I also have some "bulb shaped" LED's rated at 3.5V that came with resistors. I made up a couple of plastic light bulbs, look like incandescent bulbs, and used them at 12V in our greenhouse. Problem is, after several months of not much usage, a few of these parts are not working. ?
I have a small battery pack of A123 26650 battery cells in 6S8P configuration. That pack runs the computer/UPS/Modem when the power goes off, regularly. Gives me 30 minutes of run time and shut down, so I don't over draw the cells. Soon, I will have a smart phone with Internet WiFi, and not need to be connected to the phone line. Might even shut down the expensive phone line.

Now, Finally, I have 5 Nissan Leaf Modules rated at 15.2V nominal-16.8 fully charged. These are 4S1P modules with cells being 4.20V full charged. I also have part of a Chevy Volt battery to group with the Leaf modules. All are the same Voltage cells.
Questions I have are, how can I run what I listed using these modules? Is there a way an un educated in electronics person, can add resistors, or someone build a circuit for me, that I would gladly pay for, or, is there some other way to do this ?
Will the UPS charger be sufficient to charge the packs, because, for now, I still use the battery packs for temporary power.
Soon, I will receive my long awaited crate from the USA, it's IN CR at this time, so I can finish up several charging systems I have started. Right now, I run on 12V or so. I plan to charge 24V packs and split the usage, due to light loads and monitor each split off group.
After the first of the year, I want to buy a dependable Inverter. Then, I can run a fridge and everything else in the house, on DC or 120 AC, depending on how I wire up the house. I have plenty of experience with normal electricity. It's this Low Voltage stuff that throws me.
If photos will help, I can obtain some and post here later today.
Thanks for any and all info, ideas, opinions, etc.
