Which Battery and why
Can someone please explain the difference between these two batteries and why I should pay more for the one

RE: Which Battery and why
Before you invest in a new nimh pack, you should look at the 2300 mah A123 battery pack. Take a look at www.hangtimes.com to understand the A123. You won't regret it.

RE: Which Battery and why
Hopefully someone will answer the question though.... both 2000mah packs and one considerably more expensive than the other..... ?

RE: Which Battery and why
Well I don't know a ton about these things, but:
The Panasonic cells are smaller and have the same capacity, thus they are more expensive. It is important to note that the 4/5A pack is NOT recommended for high discharge rates associated with digital servos - they will draw too much current and drop the voltage below a safe operating level. The Sanyo cell pack is larger but is also lighter. It is approved for high discharge rates as stated on the page. Lucky you, you need/want the less expensive AND LIGHTER pack;) |

Is there any difference between 4/5a packs and AA packs besides size/weight? TIA Dan |
RE: Which Battery and why
Actually, the Panasonic is a 4/5A is a shorter fatter cell, the AA cell is longer and thinner.
|
RE: Which Battery and why
Unless the small increase in weight and size is critical, for high current operations you are better of with NiCad rather than NiMh as they have a lower internal impedance and will give you twice the liftetime (number of charge/discharge cycles).

RE: Which Battery and why
Save your money and make your own packs. I use DURACEL 2650 MAH from WALMART and the work just fine.;)
|
RE: Which Battery and why
How are you going about soldering them together?
Thanks, Ernie |
RE: Which Battery and why
Making your own battery pace is easy. Use a 100 wat soldering gun. scuff the ends of the cells, apply a little flux, then a small drop of solder. You can us Ks brass material for bars between the batteries.:D..
|
RE: Which Battery and why
Ahhh the 100 W soldering does the job FAST so as not to overheat the battery internals I bet. Great idea. I once thought it might be a good idea to put a piece of flexible wire between the cells so you could cram them into the tight places like way back into the tail or something.
