Best damn balance charger I ever had

[mistercrash]

You can all agree with everything that anyone who never used this charger as to say. I have been using two of them on a daily basis for the past 4 weeks to recharge my 20S20P, 74V 30Ah battery in my E-Moped and the balance tabs barely become warm. My battery can be separated into four 5S packs fast so I recharge two 5S and then the other two 5S.
Even doing it that way is faster than using two Hyperion 1420i to recharge all at once or two Cellpro 10S to recharge all at once because they always go into a balance charge mode that tries to equalize 30Ah cells with each other at less than 1 amp

Once the charge is done, I checked the voltage of each cell with my Fluke and they all are below 4.205V so no over charging going on here. I did this for the first 5 charges just to find out if the chargers are consistant and they are. That is with the chargers adjusted to charge at 4.2V per cell. That is adjustable to a lower voltage if needed.

So hypothesize all you want, I know what I got and I know it works well Just wanted to share.

Can you charge more than one pack at a time with this?

You could charge multiple packs in series up to 6s (6 total cells) and still reap the benefits of this charger.

Any parallel charging would negate the benefits of individual cell monitoring.

As the charger eases off at the end of the charge the resistance of the wire and connectors will have nil effect and the cell voltage can be read accurately.

I get it you like this charger and I'm not trying to speak out of turn, just seemed like a bit of misunderstanding

Like panda said, Art1ck and Brian were just pontificating and stating facts about electricity.

They said nothing negative of the charger itself, and we all agree individual cell monitoring/charging is the safest and most beneficial to the battery pack.

You're right, they're right, we're all right, just sharing knowledge.

Lol, watched the video, it looks as if you could do two (or more) packs at the same time. At $80.00 two chargers is still less than one Hyperion duo.

But the whole point of this charger is individual cell monitoring. Yes in the video he paralleled a lot of packs, but again, that negates any advantage of this charger.

If you"re going to parallel charge a $30 hobby king charger will do the job just as well as anything else.

Well that's pretty obvious, my point is if I want to go to the track and charge two 5s packs at the same time, then two of these chargers is still less than one Hyperion Duo and I get the magical cell monitoring which must be better than my current duo has been for last five+ years. So if my Hyperion Duo ever dies I may look at two of these.
