Hobby charger battery cradle.
« on: August 31, 2014, 02:47:19 AM »
I've used a hobby charger on and off quite awhile now. Because of the frustration of tangled leads and magnets wanting to do what magnets do best, stick to each other and tie the leads in knots, I bought a few normal chargers to charge batteries and used the hobby charger mainly for testing batteries.
With the C83 light I made using four 32650 batteries and only having a three bay charger to charge these batteries I decided I had to revisit using the hobby charger with a cradle that prevented the frustrations.
With no plan in mind the scavenge for want of a better expression, of stuff started. The main platform was originally from a packing crate, the quad I bought twenty years ago for along forgotten job and the aluminium angle was scrounged from somewhere sometime knowing one year it would come in handy.





I have a ICharger 208B which uses a separate balance board. Different looms were made depending on how many batteries are being charged at the time. I do have all the parts ordered including heavier wire to custom make new leads. These were cobbled together while I'm waiting for the parts to come in.



The batteries here are two 18650's and a single 17650. The 25mm quad was spaced so there was no movement of these batteries with them sitting on the base.



The four 32650 batteries that instigated this cradle. I made the cradle to hold six batteries in total.




When the big picture is to big, look for a point you can start at and build from there.

Nice work!  Looks like it's wired for series charging.  That's something I haven't done with mine yet.  I've only charged Parallel.

What set up do you use to charge parallel JM?

I have battery carriers in various sizes that I got from FT a while back.  I have a 3*18650, a 4*18650, and a 4*14500/AA carrier.  All wired in parallel so I can put in as many or as little cells as I want.
