Guys I am using an ANT BMS with a 18 AMP 48 V battery pack to drive a 1000 w bicycle motor. If I start and run the motor in the air I have no problem running it. However when I sit on the bicycle and try to power up my BMS errors out with a short circuit message. (And no comments about me being...
OK, you are a bunch of smart techies, I have an old radio in my office that has a really lovely sound to it. Unfortunately the FM reception where is is sucks. Can anyone recommend some kind of way to boost the FM signal without having a bunch of cords lying around. All advice appreciated.
This where my understanding of electricity gets hazy. By my understanding a resistor is a load and therefore theoretically would not short. However I presume a low value resistor is really not a load at all and this is when a short occurs. I'm sure there is some fancy math to determine when a...
Ok so this is what I am thinking of doing 16S pack
Connect all positive leads of active balancer to each cell (Sam as BMS)
Connect negative lead of cell to resistor I have a 6.8 ohm at hand. Is that too low
Connect negative lead to battery
Let me know if this sounds right
I need help with My ANT BNS Settings. Specifically these 2 screens. One is the connect resistance and one is the Hall speed sensor. For the resistance I presume I shoudl measure each cell and use that or use the spec supplied by manufacturer. On the hall sensor I have no idea
All help appeciated
Mike,
How would a a battery charger be different and provide a better alternative? I imagine a battery charger would also have a a hard time determining SOC.
Hi Mike, I'm intending to use it as a battery charger as I like if for the following Reasons
1) You can set a high voltage cutoff independent of the use selectable high voltage
2) I intend to use it to charge my 48 v to power my yacht motor. As such I want to be able use it to top the...
Guys, I would like to put a Diode in series for charging my 48V Bank. Charger will be a Xantrex XFR 60-20 pushing out 20 Amps. Can anyone give me the specs of the diode I should use ?
Im using a Xantrax XHR 20-50. Max Amps is 50. Batteries are 200AH with 1C. Am I right in that .2c would be 40 Amps multiplied by 20 batteries = 800Amps?
Couple of novice questions regarding balancing
1) Im balancing 20 cells in parallel. Surely the voltage at the furthest terminal from my power supply will end up with less voltage due to resistance on my busbars. How do i solve for this?
2) Related to this, how tight do I need to make my...
