many RCU'ers use the imex b6, Ive had one and they are awsome for the money. And yes, it cannot charge above 5amps, so a 6cell lipo it can not charge at a full 1c.
That charger will beep loudly when charging is done and stop on its own.
Lipos can hold a full charge for a good long time. there is no need to keep them on the charger in storage mode. I dont leave mine fully drained for more than a week. But when fully charged I may not use them for a couple of weeks.
Correct me if i'm wrong, but he said the charger specs were .1-5.0 amp charge rate @ 1-6s lipo. That means it can very well charge a 6s lipo at 1c as long as the capacity is below 5000mah....
you are right, got my numbers backwards. If it was a 6cell 6000mah, it wouldnt charge at 1c since the max charge rate is 5amps. but any battey 5000mah or below it can charge at 1c.
also, to Dounut0999:
I wanted to correct the charge time I mentioned earlier. My 2s 5000mah packs take 1 hour to charge. My 3s 5000mah pack takes alittle longer (more cells to keep balanced) and so your 4s 5000mah pack will take a bit more than that. But it still shouldnt be more than 1.5 hours tops.
Again, fast charging will take less time. But I wouldnt use fast charge unless you know the pack is only 50% drained. When a pack is fully used before being put on the charger, the chance is higher that the cells are out of balance. But if the pack still has 50% power, then the cells are most likely closer in voltage so fast charging wont hurt anything.
But you should find that your lipo will get you at least 25 minute runtimes....maybe even more. The runtimes we now get with our brushless/lipo combos is amazing. I remember when my old traxxas brushed models went 25mph top speed and only ran for 8 mins (and the nimh was wicked hot) and it was time to recharge the battery!
Now I run brushless 1/10 models on 2s 5000mah lipos and get 1/2 hour runtimes and speeds around 40mph.
