The batteries all have ideal diode's.I have a 12v/3p 13s battery I did for 12v compressor ect.I would like to try it in series with a 48v battery.The controller has 100v caps.This is for a Dapu 36v/350 watt geared hub motor
Do you mean a 3s 13p? Even then, 3s would barely get you 12v @ full charge (4.2 x 3 = 12.6).I have a 12v/3p 13s battery I did for 12v compressor
So you want to get higher voltage?I would like to try it in series with a 48v battery
To be clear, the motor itself doesn't really care what voltage you feed it (for all intents and purposes here). It'll care how many amps you put through it (because that'll be heat; which too much of will be smokey burnt up motor).This is for a Dapu 36v/350 watt geared hub motor
This sentence...doesn't make sense. What does reversing polarity have to do with anything? And, no, I don't believe there's an "adapter" that can swap around all the series/parallel connections on a battery by, like, flipping a switch.I want to series batteries. I currently have it wired for parallel. Can I make a adapter to reverse the polarity when going from parallel to series?
and second guess yourself while you anticipate a BIG BANG! on first test..With a four pole double throw switch, you could rig 3 batteries to be in series or in parallel. It has to be a break-before-make type switch. Each battery needs its own BMS, and the BMS has to handle the combined voltage of all three. Sit down with a pencil/paper and you can figure it out,
That's why we let him figure it out.and second guess yourself while you anticipate a BIG BANG! on first test..
Series not parallel. I use 2 48v in paralleland second guess yourself while you anticipate a BIG BANG! on first test..
Whats the use case for connecting a 12v? and 48v battery in parallel other than danger?
I did but I don't want to redo the wiring just to check out 60v.That's why we let him figure it out.
I am curious about 60v performance but it's more hassle than I am willing to endure just for curiosity. 48v is pretty impressive with this motorI wouldn't bother with it.
You have a lot of new problems doing this with a battery that has a BMS.
The end solution would be expensive, heavy, and complex.
RC Lipos with series/parallel adapters might be more ideal. You can play with increments of 8-22v. But there is an art to using them safely without burning your house down.
