What is the Best Battery

[GorillaMaxx360]

What are the best Ni_Cd battery cells. As for runtime and good puch.

Why would you want to run Nicd? Id take Nimh over Nicd any day.

But to answer your question, probably the Sanyo 2400's. (Not sure if 2200 or 2400).

sorry i ment the other i think the batteries that are like 4300 mah and stuff.

[GorillaMaxx360]

i ment batteries like these

[Sylvester]

You mean Nimh, Than the GP3300 and GP3700 are the best. And if your an IB fan than the IB3800 are also good.

[GorillaMaxx360]

what about the ones i sent the link to they seem to have a high mah level and they are race quality.

[Sylvester]

They are good for runtime but arent the best for dis-charge rates.

A rule on nimh batteries is ; the higher mah a battery contains, the harder and less likely it is to have a good dis-charge rate.

I am not to familiar with batteries so can you elaborate more. does this mean i get long runtimes but it takes for ever to discharge. also with these batteries do i have to discharge them all the way to dead before i can charge them again. is this with all matched batteries. because if it is all about discharge rate then i do not care about how long it take to discharge aslong as they have long run times

I think Sylvester means that they can't cope with high discharge rates. A good battery will maintain its voltage level under heavy current draw. A bad one won't. ie. you pull full throttle and a bad battery will supply less power than a good one.

Never discharge Nimh cells to dead. Even Nicds shouldn't be discharged to dead in a series battery.

The problem with the 4300's that they drop sooner in voltage on a lets say 100A load. the GP33 and 3700's keep a higher voltage on a high load.

the IB3800's deliver impressive power too, but they are not as durable as the GP 33 and 3700

so i should get ib3800 then and i do not discharge them after i am done driving them dead in my car i can charge them again with out discharging. also what kind of runtime and speeds am i looking at in a revo with 51/18 gearing on a 8XL.

You shouldn't even drive them dead in your car. :)

that would depend on how many you go? 14?16? If 16, most likely 20 min or there around. And no, no discharge at all after run, in fact, I would stop after they really get slow and not until they cog, but slow. Otherwise, GO LIPO!!!! LOL

so it would be the same runtime pretty much if i got 16 cells ib3800s as i would the 4800 orion packs. Would i get more power since i have more 14.8 volts like the orions. Also with these batteries(matched 3800s) i should follow the same procedures is i would would stick packs right.

[GorillaMaxx360]

I just was on rc calculations and i put in the items needed the first time around i put in 14.8 volts for the 2 team orion batteries and the second time around i put in 19.2 volts representing 16 cells Nimh the speed almost increased almost 10 mph does this sound right. Also can the 8xl with heatsink and the quark 125b w heatsink handle 16cells. (i think so just making sure). so for my purposes do you guys think nimh will work for me, for many reasons like: Can get like 10 more mph with more cells and voltage, cheaper, more basher friendly, more tolarable, and such what do you think about these batts for my needs. I now you guys like lipo but i will not need more than 15minutes and the ib3800 should do me good and i should get good voltage with not a huge drop of of voltage what do you guys think.
