Re: 14....or 16s balance charger?

Re: 14....or 16s balance charger?

? Balance charger as a daily charger for R/C lipo only. Daily ever time all time . A battery build right used right will work right. A junk battery is junk. Don't build junk. What battery cells you using ?

Re: 14....or 16s balance charger?

Close is a un9plus+ a 9s charger times two is 18s and a 16s is two plugs. If you have a working battery it does not need balancing a shitty or wrongly used battery DOES. I had both 1429 and two 1220 done no support. Jumk.

Re: Balancing a 20s battery back

Yes and the closer you get to end voltage the more you see diversity in the voltage number. Meaning at 3.9v they are all at 3.9v and may only show voltage more different at top of voltage and at 4.3v only one will race to 4.5v and above. Meaning you will drive out the weak cell at lvc and hvc andabo...

Re: Balancing a 20s battery back

It's about how low you go or how hard you hit them. This is when unbalance starts. Can you put an alarm for lbefore lvc on your uni. Pic of uni.
You have a unicycle like Justin ( are leader ) 30mph ? You bulk charge with what ?

Re: Balancing a 20s battery back

I did have the hyperion 1420 it was 14s and it broke. I bought a Thunder Power 1220 12s charger it broke. Yeah so bought another one and it broke. They don't sell either one of these Chargers anymore probably because they break. If you're using the battery pack properly it should not go out of balan...

So you can plug in eight 6s or eight 5s. It charges...

Did you buy it online ? Contact suppler for replacement. Such a new bike I would think would have a cassette and not a Freewheel on the rear.
