Those little packs have 2 of the 1100mah cells in them.

1100 cells (VPX Black and Decker)

Walmart had dropped the price to like 17.88 or something like that, but now it's back to 20 bucks again.

I'm using the 1100 cells for a special light I use at work... but I have been wanting to try a 2s2p or 2s3p pack in a 1/10 car just for kicks.

next time Lowes sends me a $10 off coupon I might pick up another pack or two.

I wouldn't use the 1100mah cells in racing though. Just stick with the 2300mah cells.

I have newer SC cell 950mah and run 6.4V 2900mah 2s3p
and soon i test 2s2p or 4s1p with esc same side of my pack

for offroad i think it was better than lipo

same speed with good gearing but little less torque on start

better smooth start and more smooth on slipper and drive shaft

you need to make small adapter with 6 A diode to lower voltage of lipo charger to 3.6 - 3.8V best for lifepo4 cell

the big diiferency is the power up at the middle of the race same with the temp of the cell

you can wire the 1100s up in parallel to make a 3300 pack.

i have a 1100 mah Black and decker battery that i've experimented with, and its pretty damn durable!

i've overcharged it, over discharged it, and even (accidentally) shorted it! and yet it still works. I am just running 2s1p, and it runs OK, but thats because its too much amperage for it to handle (thus votage dips). i'm sure if you hooked two up in parrallel, it would work much better.

i was thinking this battery would be good for a "spec" class, both on and off road. cant gear too much, and since its such low power, brushes dont wear as fast. Plus they come with a hard case (Roar legal?)

Cheers!

What is everyone using to charge these cells? The only lipo charger I have is the Ice.

The chargers used are very similar to traditional lipo's, except the voltage is different. with the cells i use, 3.3v is the max charge voltage.

I dont have an official charger, but i use the motor break-in feature on my 989 to supply 6.6v (3.3v/c) at X amperage. when it reaches 3.3v, it will reduce charge current to keep it at 3.3v.

cheers!

The motor break in feature sounds like it would work but just seems alittle to advanced for me lol :lol:

good charging method with motor charger

but the final volt is 3.65V to 3.8V

best ajust your charger at 7.3V for two cell

The people investing their lively hood into r/c do not want to see a true spec class. However, I also believe that these new technologies can help r/c racing to boom since you no longer need to spend $500 on battery tech.

ok so if i get a123 cells do i need a balancer, and will ithave longer runtimes like lipos give you? and where is the cheapest that i can get them

If you want the 2300cells then purchase a dewalt 36volt pack. They have 10 cells in them & can be purchased for like $120 off of ebay. For the 1100 cells purchase the black & decks packs. A ballancer is not a must, but I would recomend using one. If you want alot of run time then wire them in parallel.

can i charge these with a lab power supply? it would be constant voltage, so as the batteries hit full charge it SHOULD srop to about 15mah or whatever the cells need to overcome internal resistance.

The only other charging method I have heard of is what people car zip charging where they some how hook their packs up to a car batter & charge them in like 5 minutes.
