I balanced my 5 packs of 20p cells to 4.02volts by paralleling them together. All of my cells are new from new replacement laptop batteries and hover board packs. A couple days later one of the packs was at 3.96volts. I thought it was odd at the time but didn't think much more. Yesterday I...

I want to attach a little LED voltmeter to my packs to monitor the voltage of each pack. How do I wire it to each pack so it displays the pack voltage and not overall voltage?

I am looking to the near future and see a Batrium system. My question is on their site all of the "Starter Kits" are for 14s 48volt systems. Is there one for 24 volt or can it be used for a 24 volt setup?

I am considering how I will make my series connections between packs. I like Average Joe's idea of using pluggable connections. Ive got some XT 90 connectors that should be sufficient for this purpose. My question, is there any reason I should not make my connections like this? I plan...

It's not the prettiest but it's my first. All the cells are 1800 mAh new cells. I got cheap replacement laptop batteries.

Could someone please describe top and bottom balancing? I understand what it is to balance packs, but I'm unclear on the meaning and reasons for top or bottom balancing.

I apologize if this has been addressed here before. If so I have been unable to find the thread. I am looking at the different 4 slot charger/discharges, and I can't decide which one to purchase. I have been reading reviews on the lygte-info.dk website and I just can't decide which to get. The...

I've been lurking for a while attempting to learn. I thought it was about time I actually introduced myself. I'm Alec and live in Kansas. I'm a clinical scientist by training and decades of experience, but I now work in health care IT management. I currently have no solar or battery...
