the wiring isn't damaged, was just a little flattened. and anyway, I'm pretty sure its a single cell causing all the issues (its discharging fine and linear but the recharging is erratic to say the least!) but when i look at the price of the single cell and the new soldering iron i would need, just makes sense to go to lipo.
Just wanna check a few things. Lipo's on it's way. I'm guessing u discharge first then balance cycle a few times? And at an event, can you top up the battery after a fight or do they need to be full discharged then recharged?
Don't bother discharging them. Lipos don't like being discharged like nicads and nimh. Just charge them up and the balancer should do it's job on the first charge.
You shouldn't ever need to cycle Li-Po's it won't do them much good either.
It's all finally arrived and as my luck with batteries and chargers isn't amazing I wanna run through a few things first.
1. Will the charge time be the same as previously with a NIMH battery, if everything is constant?
2. The charger has a storage function that seems to want to bring the battery to 3.7v per cell. I'm guessing this is my discharge function? As the discharge function wants to bring the battery to 18v overall?! And that's bad for lipos isn't it? I want to charge the battery up just to check it's all working but I don't want to leave it fully charged (or is that ok for lipos?)
3. Lipos should be stored at 3.7v per cell, correct?
Thanks

I've looked into the storage mode and it does charge/discharge the battery to 22.2v. I just need to know the very rough balance charge time (for the timer cut-off)Originally Posted by Danjr1
thanks
I think storage mode is deigned for when you plan on actually storing you Li-Po, ie. not using it for a long time. What you want is balance mode, just keeps the amps low.
I'm currently charging in balance mode at 1.5A then ill leave it a while and storage discharge it to 22.2v, just wanna check everything is working but the new battery is a beautiful fit my bot!
Also, the difference between the lowest and the highest cell is 0.1v, that good or bad?
Why are you discharging? You should avoid doing that on Li-Po's, just charge until you have 4.2V per cell. They should all be 4.2v.
Try balance charging at 1a, or less.
not discharging yet. I've read that storing them at a full charged state isn't great so i was going to use the storage function which will discharge to 22.2v? i don't want to stop the charge now (but i wish id known! lol) but next time, ill balance charge at 1A
