Peak Char-G'd!
 

I just used my high-end peak charger to charge a pair of BC-Gs w/ stock 50mAh cells, and the results were staggering! Not only was there more punch (proved by new lap records set with both) but the runtime was just unreal - over 30 minutes - with stock cells - driving flat out the whole time!!! I want to try it with a 150 cell next - I just need to find a 2 hour block of time to spend wearing the cars down!!!

High end peak charger?

Strange that you post this.

I have a second controller that I was going to tear down for the charging pad. I was planning on connecting it to my Tekin BC110 and giving the 'ol MS batts a peak charge. It's nice to know that it works so well.

i.e. that which is used for charging packs on larger RC cars; instead of timed charge, it monitors the cells and charges them properly! :)

That's exactly what I did - took the charging pad from a spare Tx, soldered on some fatter wires, and jacked into into the 1-14 cell charger. I charged at 0.5A - I'm not sure if I want to push it any higher just yet!

Wow, this is nice info. Can I know what model peak charger you use? ,, how much would it be?

hmmmmm SO the Peak charger didn't mess the batteries up??? COol!! How long did you have to charge it for???

Blue bit- peak charges can raange from $30 to $100 maybe even more for high end ones.....they're used for lager RC's like 1/10 and all. I wonder if using a normal 15 minutes charger would work, probably not, you can't set the charge- leve either, i don't think, gott go look at my charger........

thanks:) I've been looking around the net for one, but I want to know what model/make tinyrc used. I never got a chance to get one of these back in my1/10 days (about14 yrs ago). The $30.00 ones I saw I beleive had a constant voltage rating ( I may be wrong)

The charger I used is $140 :eek: - probably not worth it if you only drive Bits, but I now use it for BC-Gs, Epochs, Mini-Zs, Micros, and even the Rx pack on my 1/6th Nitro Elise! If anyone is interested in a new charger, email us at the Shop we can get you a really good one at a discount. Note that it's very hard to find one that will work with a BC-G, because you need fully adjustable charge rate; some will allow a choice of 1A/2A/4A etc., none of which are safe for this size of cell. In addition, most chargers will do 6-7, 5-8, 3-10 or some similar range, but not many go down to a single cell.

I have a super brain 959 peak charger. What amperage did you set your peak charger at, also what charge rate?

I charged at 0.5A, which is a choice on the 959, so you should be okay there - however, the 959 is intended for 3-8 cells; you may be able to use the single cell mode for the 1/3AAA cell, but I would call MRC before attempting this to make sure it's okay. :)

you are right, it's a bit too much for me at this time. But eventually I'll invest in one after i get a miniZ & epoch. But thanks for the info, this is good to know:)

Please post your results with the 150mah nimh's as soon as you get them. This is cool! :)

I've been experimenting with the 50mAH cells, and they've been taking 67mAH or so of charge. The 30-40 minute runtime is starting to make sense. I've been charging at 0.5A and it takes about 6 minutes. This makes perfect sense, since the cell is 0.05AH. In order for the controller to charge the cell fully in 45 seconds, it would need to charge it at 4A! That would explode this tiny little cell! As such, the default charge time must only fill the cell a tiny fraction of the way! I'll do the 150mAH test soon, I just need to set up a relay team because I don't have 2 hours straight to spend wearing it down! :D

So can you reach peak capacity with the controller if you charge long enough?

With the 150mah battery users getting 3x as long run times, it may be b/c they're charging it 3x, expecting the batt to hold the charge. If what you're saying is true, you should have the same results charging the stock 50mah 3x since they never reach capacity. So the increased runtimes are just due to our expectations of increased capacity and our resulting longer charge times? :)

Can you simulate the effects of charging with the controller to find out how long you have to charge to *really* reach capacity?
