Pulse Charging, also known as burp charging has a very small dishcarge pulse every second. The theory is that it helps to break down the crystaline structure which forma in the cell over time. I read an interesting Nasa study about it a while ago. They found that it really helped to extend the lifecycle of the cell. I'd like to do extended cycles for things like this but I don't have a charger to dedicate to it for 6 months and I certainly don't have the cells to throw away.

I thought this wasn't supposed to be good for Nimh cells? Has anyone done this on their 3000 or 3300's?

I think it's also known as flex charging, and as far as i remember none of my chargers recommend that for NiMh..
Is it recommended in your Pro-Trak?

lee,

It's more of a personal preference thing, if it works for you go for it. It's available with Pro Trak, whichever you use is up to you. I did not get good result with it comparing end data. I had better results with Hard pulse and Multi Phasic Charging. I do still use linear when racing though, I want some more good results to come in before I start using different charge methods.

Adam, you should have talked to me dude. I am sposored by SURGE and I would have recommended the best cells for you to get from SURGE.

Oh well never mind.

If you cycle a pack on a turbo 30 with pulse or flex charge, the numbers will go way up.. but the pack will run flatter then a prctice pack... a true linear charge is and always seems to be best... ive tried both.. and with the flex i was almost a full lap off the pace... these are just my findings, but i know others who have tried it with the same results... ill take mad rip over life cycle of a pack...

Burbs,

I agree, I do not get good results from repulse charging, much better by the numbers is hard pulse or multi Phase charging though I have not tried it on the track. I'd guess that the turbo thirty does not take into account the discharge spike when calculating the Mah.

One thing I do though. If I'm charged way early before my race (say more than 20 minutes) before peaking I set a discharge for 20 or 30 seconds first, really wakes up the cells as compared to just a straight repeak. I have found that repeaked cells can feel flat sometimes. This does help.

Chris.
