I have the H27 version software in my Tekin BC112.

I can choose from the following:

- P
- P2
- CS

My questions are:

- will the "P" mode work fine on 3000 NIMH batteries ?
- will the "P" mode work fine on SCR2400 NICAD batteries ?

P2 is repeak I believe

CS is cold start.

Is it easy to upgrade the software version ?

Thank's

hi,

H27 is fine to charge NiMh, you switch the powerflex off, then select either P or CS. thats what i says in my manual,

For Nicads i personally leave the powerflex on PF3 and then use CS or P.

I occasionally get a false peak with a crap battery if I use P, but I've never had a false peak using CS

have a nice day

I tried P mode a couple of times on some general 1500 NICAD packs and it only went to 1120 mah. Is this a false peak ? Does false peaking occur at the start of the charging process or can occur at the end ?

The PF mode was off.

Hey Schumacher, do you have any NIMH batteries and a H27 version charger ?

Some people are saying that the H27 version is NOT compatible with NIMH batteries. Check this out

Confused ?

hi canuck,

I have H28 software on mine but I KNOW from the Tekin website when it was up that anything with H26 software or above is fine to charge NiMh.

Whoever said you need H28 its BS.

False peaking can occur anywhere during the charge cycle, feel your batteries after the charger has stopped. are they warm? if not then chances are its a false peak.

I would reccommend you use the CS cycle as it uses some algorithim to work out how flat the battery is and it never seems to false peak on mine. in P mode the peak detection is very senstitive.

I have a manual for the Tekin charger on my website as well as a review.

have a nice day

Thank's Sanj. I kind of thought that is was BS ! So many people are quick to give answers but the info is not too precise.

As for your website. I read the review you did on the charger, it's great ! I also have a particular passion for YOKOMO because I just recently acquired a mint Yokomo YR-4M2 with full graphite chassis, graphite front and rear shock towers, full bearing, full cvd's, blue aluminum front and rear arms, blue aluminum front "C" hubs on the car and the rear uprights are also blue aluminum.

I can't find much info on the setup for this car on the net but I have the manual and plenty of spare parts also.

Can't wait till spring !

Hey Sanj, here a photo of my YR-4M2

So far with my H27 software here's what I will use for charging: (any comments or re-ajustments to the values ?)

Nicad 1500mah sport pack: 4.5 A - CS mode - PF2
SCR1700: 4.5 A - CS mode - PF1
SCR2000: 4.5 A - CS mode - PF1
SCR2400: 5.0 A - CS mode - PF1
3000 NIMH SANYO: 5.0 A - CS mode - PF1

schumacher

for the Nimh use PF0 or basically Powerflex is off.

For the other batteries (nicads) I personally use PF3 but PF2 is what it recommends in my manual.

have a nice day

Well on the H27 I have P mode and not P0. So I will use that for the NIMH.

As for the nicads and the Powerflex settings, the PDF manual says the following:

PF1 >> mostly used for SCR cells

PF2 >> normal setting for SCRC, SCE, P-170, 2000 or for general nicad charging. (So I guess it's OK also for SCR NICAD cells ?)

PF3 >> maximum conditioning of cells (I thought this may not be as better as the PF2 ? But you have some experience on this ! Will the pack have less performance on PF3 compared to PF2 ?)

Thank's

Sorry, I just realized that what you said about PF0 is correct !

Get's confusing !

As for the nicads and the Powerflex settings, the PDF manual says the following:

PF1 >> mostly used for SCR cells

PF2 >> normal setting for SCRC, SCE, P-170, 2000 or for general nicad charging. (So I guess it's OK also for SCR NICAD cells ?)

PF3 >> maximum conditioning of cells (I thought this may not be as better as the PF2 ? But you have some experience on this ! Will the pack have less performance on PF3 compared to PF2 ?)

schumacher

when using PF3 or maximum powerflex the burp that it gives the batteries is bigger than on PF1 or PF2,

I just always use PF3 as the cells seem to stay a bit cooler so i think this is a good thing, I don't think there is much difference in it but i'm no electronics expert so can't really say.

have a ncie day

Hey Sanj, I tried the PF2 mode on my SCR1700 pack and it charged to 1400 mah only ! Is it possible that it will need a few burp mode charges to peak back up to 1700 mah ?

Canuck

I also tried the same for a SANYO SCR2400 with PF2 ON and charge rate at 5 amps and I got 2030 mah ! Yesterday I did not use the PF mode and got 2350 mah !

I guess it's looking like the Powerflex does not do a good job !

schumacher

you should take the numbers you get out of the charger with caution. there is likely to be some power left in the cells before you charge them hence the actual power you stick into them will be less.

also unless you equalize your cells, then the peak detect will register as soon as the first couple of cells are done.

just one other thing to note, the reading I get from a millenium charger is 2650mAh into a sanyo 2400. However my tekin only register 2260mAh, having discharged the cells both times, there was almost the same power in each +/- 3%.

I think the tekin has much lower resistance in its output circuitry so there is no power wasted in heat build up hence the lower Ah figure.

just my theory....

have a nice day
