yoyoman wrote:not a very good ride to work today after reviving the batteries. I started out with the watt's up reading 40.25, and when I got to work, it read 30.5! I could tell along the way that it was not performing well.
When I got to work, battery A read 39.5V, but battery B read 30.5. Yikes! I had charged both a few days ago until the charger stopped, which was around 40.x V.
Do these need to be reconditioned with some short rides, charges before riding them hard again? I wouldn't say my ride is that hard ...
Update: I just charged the low battery on the stock charger. It went to 40.6V in less than 30 minutes. Does this seem too fast?

Then you could leave the slot connector on one end of your pack, maybe even include the status of charge indicator. It would probably take 6hrs for a full charge, but slow charging and the more conservative charge level of 40.5V will make them last longer.

If i make the final voltage not more then 41v by puting enough diodes in or tweeking the SLA charger TRIMPOTS can i leave it on charge indefinetly ? or does it still need a timer to stop it ? isnt it the case if the final voltage of the batt is 41v and the charger is 41v then no voltage will flow henc not a problem?
If i can't use the SLA chargers easily is their any cheap off the shelf 36v Charger to suit these bat 836 batts for 240v input? i don't want to use the bosch chargers
I have been reading in this thread that these konions need a 3.0v Cutout hence for 10 cells in the fat pack thats 30v, how is this LVC cutout done in the bosch tools ? the battery has that volt meter on it what output does that give the drill to tell it to stop ?
