Lithium Batteries

[koko64]

My Shorai battery was discharged under 20% capacity, the Shorai charger will not charge a battery under 20% capacity and will flash a dead battery code. I had to put it on a trickle charger for an hour which raised the battery over the  20% capacity so the Shorai charger could begin to charge it. Something I learned from YouTube!
The new, deltran battery tender for lithium batteries, will sense and charge battery's discharged to 8V!

Who is a good vendor for these Deltran Li chargers? Are they adjustable for time duration when not charging/charging interval and max charge voltage before cut off? Any forum sponsors sell Deltran or Ctek gear?

I think my buddy has a Ctek Lithium charger that's supposed to do what I''ve been doing manually.

Hopefully some of our forum experts on electrickery will chime in.

Optimate TM291 looks good. Antigravity sells them.

I'll look for a list of regular chargers approved by a manufacturer for their LiOn batteries

Thanks mate.
Cheers.

So far I have seen, Deltran, Ctek, Optimate and the Shorai unit which I think is useful, but limited for my purposes.

I have been emailed a list of chargers and had a good think about which ones were recommended and which ones were not..

Put simply, dont use trickle chargers or regular battery chargers with Lithium batteries. Use a non trickle charge Lithium battery specific type charger. Trickle chargers may under charge and regular chargers over charge (with safety risks). I am happy to forward the information for you to decide for yourself, but trickle chargers will generally fail to fully charge a Li battery and shorten its lifespan by only maintaining it at its minimum operating voltage. A regular charger with desulph mode can cook a Li battery quickly with all the potential consequences. Check out the EarthX site for their recommendations.

I only have a basic understanding of "electrickery" and regularly consult others who have an expert understanding. I hope this general guide helps you safely take care of your Lithium battery. They will probably become the norm over time so it is good to learn about handling them.
