Who using A123 batteries?

[sherman89]

I had my first 123 pak go south on me, after about 60 flights one pak decided not to take it's normal amount of mah's that was expected and when I checked the cell v I found 1 cell at 3.34 and the other cell at it's normal 3.6. The pak only took 39 mah's when it should have taken about 1200 to match the second pak. I cycled the pak twice and now the bad cell will not come up from .55v. These cells all started out as Dewalt paks purchased new. This the first time I have had a problem with several paks in 35% and 40% models. I will not take a chance and the pak will be replaced.

This is my fifth year using Fromeco batteries. Never had a problem either. However, I do replace them after about 2 years. Would be interested to see if balancing the cells prolongs the life of the battery. And what the difference is between the balanced/unbalanced cells.

To balance, I'd have to take off the cowl which of course is a pain in the arse. I never balanced the Li-Ion's and they've given me 3 years of good service.

If you have a charger that connects via the packs power connector (instead of a balance tap), you can just add a balance tap to your A123 pack and attach a "blinky". Then just charge through the charge jack and the blinky will take care of balancing the cells.

(sorry, I haven't read the whole thread)


is anyone familiar with 42% products A123 packs? I'm wondering if I can charge them through the regular lead, or if they have any circuitry built into them to prevent that? (I don't have a balance charger)
