    Hi Smigul :) huehuehue. i remember your name on some PH Tamiya Mini 4wd Groups. the one with a captains hat i believe. am i correct?

    well anyway regarding your query. I have a tip for discharging. there is a way to fully drain the energy of the battery to ensure that you can charge it from 0% to 100%. since it is not advisable to charge batteries on and on even though you did not really drain the batteries. there is a multifunction battery charger. i think its the Powerrex charger that has a feature where in it will acually discharge the battery to 0%. doing it this way before charging to 100% is one of the best way to maintain battery performance and life :)

    when using NIMH batteries, Saybi is correct - you want to first get them down to 0% before charging them. They don't have a 'memory' like NiCDs do, but they will only charge part of the way if not fully discharged.

    when we were still using the 'round cells' in 10th scale, we'd even store the 6cell packs dead shorted (discharge to 0% them dead short them, connect the negative to positive). this kept the packs in the best condition.

    if you're going to cycle them - make sure you leave enough time between cycles so that they can cool off before charging them again. 3 or 4 cycles should tell you the good batteries from the weaker ones.. then just match them up accordingly. that's how I used to do my AAA cells for mini-z - 4 cycles, look at the average volts, internal restistence (lower=better), and run-time. then match the closest values together as a 'pack'. these are easier since it only needs 2 cells for a pack, so you won't need as many to find a few good sets. the better the sets because 'race packs', next level would be practice or qualifying packs, and the lowest would strictly be practice packs

    hope that helps

    So, it is advisable to always discharge NIHM batteries before charging and using them?

    i haven't been only because i pre-charge before i go to an event, but you'll get better performance if you did

    Hi...It might be easier and less expensive to go a different route. Go to Amazon and get a cheap timer and multimeter. Go to this website and scroll down to "How to Check Pedego Battery at the Discharge Port" to see how to use the multimeter to check the voltage. This is all really simple; easier to do than to describe. A 48 volt battery reads at 51.5 volts at 80% charge. Experiment a little with the charger that came with your bike to find out how long it takes to get your battery to 80%. Then use the timer -- the one I linked has 15 minute divisions which is close enough, you might be a little over or a little under but with no practical consequences. 15 bucks and you're set up. You might find other uses for the timer and/or the multimeter too, so that's a bonus.
