Re: bluetooth BMS?

Discharge testing:
Quite an arc disconnecting a 25a 25v load.
I used the manual disconnect in the app. Worked perfectly.
Is it easy to do with the 12s bms too.
That’s one anti-spark solution.

Turn off disch mos when done riding.

Picture the dc equivalent.
Two 12v batteries in series. Middle connection is considered neutral if used as common or ground.

Re: New Chargery balance charger in production

You can certainly do 12s with it. I don't know what the production model will have for sockets and adapters.

They didn't quite finish production before cny.
Some time in March.
I'm hoping it will pop up soon an chargery.com.

Re: Need help with a transformer

It may seem like a dead short. 2kw is a pretty big surge load. Make sure all the other jumpers are open. Primary and secondary. If it still kicks the breaker use a high watt lamp in series. You need to connect differently for use as an autotransformer. Connect primary windings in series. As shown fo...

Re: LTO Lithium Titanium Oxide (Titanate) Battery 30S - Seeking the Ultimate Commuter Battery

Yes, that BT bms is great. I have a 32s connected to my 32s jump pack.
Also have some 24s 100a versions.
I've been running the 24s 300a in my Gem truck for a couple years. 22s 110ah Volt.
The display backlight is flakey. Other than that, fine.
