Hi all, I would need your 2 cents on a good controller where I can tune some basic parameters. I have been on EB309s until now from EM3EV (with IRFB4110 FETs for those playing long at home) and absolutely love the XPD interface. As you may guess by now, I was surprised as heck that these...

Any news? Thanks for all the data

Thanks for the amazing suggestions. I moved house 10 days ago and I have just gotten around to the hobbies. Passive BMS is not my forst option, but look, if I have to leave the pack overnight or over the weekend to balance (however slowly) no big issue, as long as it gets there. In order to...

Thanks for the suggestions. I want to make a very lightweight ebike pack: 14S1P Molicel 45B. Max current would be some 20A, continuous discharge around 5A Some for of Bluetooth / app for data logging would be appreciated

Hi all, what options would you recommend for a 14S BMS? It just needs to have some form of balancing. Not sure if it is realistic to aim for active balancing, thoughts?

Thanks guys, there are some pretty good ideas. In the mean time I found a junkyard site that seems to ship to Sweden and Norway, maybe others too, here's my search...

Hello my friends, looking for some advice on a DIY energy storage project up to 20kWh (as close to) I've been looking to build an energy storage project for years, now I have some time. I have built ebike battery packs, and am working on 800V packs for work, so I have some idea how to keep...

Thanks dominik, that looks like a great shout. When they say 36V, I suppose they actually mean 36V, not some weird range like for li-ion cell packs, right?

Hi all, I'm looking for a AC mains to DC power supply of about 70V (min 66V) to power a 360W FRNSI DC6006L adjustable PSU. I'm not sure what is the maximum it can take, need to open it up, but spec says 70V. I have to assume it has 80V caps, but I'll check. After googling, ebay and alibaba...

Hi Magsy, thanks for the idea, glad to know nothing really changed from us user's point of view. About the bustoms bit, a friend of mine has a resonable big order from bmsbattery stuck in costoms for several weeks already. Not great TBH

Hi all, I have a somewhat obscure question. Turns out due to Bxit, starting in 2021 when buying stuff from the continent, we need to pay VAT. I have purchased previously battery cells only from nkon.nl, and had very good experience with good quality cells, reasonably fast shipping and very good...

Hi amberwolf, thanks for the reply. Here's my late feedback. Turns out the S09S doesn't work below around 23V without mods. I have checked with a PSU, trimming down the voltage until I got a cut. Exactly why it cuts, I'm not sure yet. Could be software limits, or as you say, could be hardware...

Thanks amberwolf, makes sense. The controller is meant for 36/48V. Any way I could modify the LVC in the BMS Battery S09S controller? I have a lot of experience with Infineon-s and XPD, but not with this.

Hi all, as the title says, I have a bit of an issue with my new setup. It's my first time using the S09S sensorless controller. Motor is a Q128 36V and 201RPM winding on a (for now) 24V battery. Top speed is a bit low as you would imagine, but the battery is capable of 7-800W in a pinch. I...
