Mini Inferno Threaded Shocks

ok i have a battery charger at home, so i bought the GP1800 to recharge lor.

i try to test it out 1st then see how

I don't really know or understand the science involved in a Electric Motor/ESC/Charger/Batts set up. (i like the smell of nitro more. )

I think (and this is pure speculation on my part) the punch comes from the ability for your cells to discharge. That is the amount of current the cells can pump out at one go. The more amps the more torque thus more punch.

I was told that the harder you charge your cells (ie at a higher amp aka quick charge) the bigger the amount of amps your cells can discharge. Thus you should set your charger amp as high as the temperature of your cells will allow you to.

that is what i always think so, till someone tell me otherwise.

Think you're right there but AA cells as a whole, still has dismal discharge rates. That's why even with 2500mA of storage capacity, you won't see ppl use AA rechargable cells to power their 1/10 EPs.

Not sure about your 'the more amps the more torque thus more punch' statement, though. IMO, it should be the higher the rate of amps discharged, the more torque thus more punch.

No matter how dismal the discharge rate of the AA are, They are heaps better the dry cells. Won't be able to load/fit 1/10 C cells on a half 8. So that was out of the question.

2/3A cells soldered in packs of 8 was an option i considered but the dicharge rate won't be much higher then AA. Also I had problem locating single cells in the 2/3A size. I could have gotten RX pack and rebuid them into 8 cells pack but that was not cost effective. I might try them if i can find some decent priced 2/3A cells of decent amps. Currently simlim sells gp one for 5 bucks each and they are onli 900mAh.

Does anyone know how are lipo's discharge rate compared to NiMh? Was told they dischagre at a much lower rate tht is why using them as Rx packs may not be good.

Yah, sub c cells are out of the question for H8.

I think the 2/3A discharge rate is not much higher than AA cells. KAN 1050 has 20A discharge rate while GP1100 apparently can go as high as 40A!

Yah, it IS a problem getting the 2/3 cells here. Anyway, if you are interested, I know X34 has some GP1100 cells to let go at $4 a piece. Dunno if he still has stock.

Else you can order some KAN1050 from ACW at USD$1.75 a piece. Small parcel post is USD$2.50 so it's not that bad.

LiPos, IMO, is very diverse in capacity and discharge. For example, the ETEC 2S1P 1250HP has a discharge rate of 10 - 12C continuous, and 20C surge. That's 12.5A - 15A continuous and 25A surge.

Just be careful when you get LiPo, dimension is a very important consideration. Currently there's no standard so LiPos come in various sizes, so getting one that fits into the batt compartment of the H8 is very important.

Cheers!

Shoot! Write wrongly and can't edit!

I meant to write I think the discharge rate of 2/3A is significantly higher than NiMh AA cells. Don't have any discharge info of the AA cells though.

[yehyeh]

Given the cost of the 2/3A it would be better off the buy lipo packs instead. The kyosho 2/3A pack is SGD 96.00 each. You be better off getting 2S2P of 1700mAh....must longer runs and more POWER.

hi mad armour, But with the high discharge rate of Lipo, will it cause harm to the motor?

According to Mad Armour isn't the discharge rate of Lipo (That's 12.5A - 15A continuous and 25A surge.) lower the NiMh (GP1100 apparently can go as high as 40A!).

If you bring it in from HKG, it's $50 including shipping. Wah, I thot it's already expensive for a pack of batt, the Kyosho one is even more ex!

Dinball

Buy KAN1050 cells from ACW and DIY. USD$1.75 x 8 oni. Think shipping is $2.50. Share and buy a few sets, then DIY. Total cost can be <$30 per pack.

Cheers!

I've been using 2S1P to run my Mini-T and Duratrax MiniQuake. So far no problem.

For Mini-T, it's stock electronics, while for MiniQuake, it's stock motor only.

[yehyeh]

Mad armour, good idea maybe we should buy a set each and try out the KAN1050 cells, for
hey Maddy..pls. start a group buy lay...provided shipping is only USD 2.50

"Parcel Post
The "Small Packet" Parcel Post service (from $2.50) is extremely reliable to USA and Australia, and is insured up to $250.00.
More than 90% of Parcel Post shipments arrive in seven days or less, with many of those taking four to five days. About 9% take seven to fifteen days to arrive, and less than one percent take twelve to twenty-five days in total. Worst case delivery is 4 weeks.
(statistics for USA and Australia only - all other countries could take 1-8 weeks).

Except for USA and Australia, there is no insurance available for Parcel Post, and you may have to wait 8 weeks or more. It really depends on the country. Belgium, for example, often takes 5-8 weeks. Virtually all packages eventually arrive, but yours may take a long time to arrive in the worst case."

Orders above $250 is required to shipped by EMS, which is more ex.

This is my self-made pack.

NICE WORK!!!!

How much did you made that for?
