Re: Bluetooth DC energy monitor

really excellent work here. I've been looking for bt enabled power meters for years and always thought it was a no brainer. Glad someone is finally doing this.

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

Hey guys. This has been playing on my mind a while. I dont think the circuit for the 80v to 15v is anywhere near as robust as required. With that said i bought an 80v to 15v circuit on alibaba to off load this job from the brain board. I will reiterate i have very limited time to help but i will sen...

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

Id imagine that part of the circuit is only 15v or 5v so 30v should be fine. No idea what went wrong maybe a short somewhere?

Re: 24v 8s lifepo4 pack for camper conversion aux power, how to connect together?

the eyelets may not be copper but they are sold as such. I am going to give it ago, no harm in trying and I have copper lugs as a fall back but wont be anywhere near as neat and tidy if I use them. I have quite a bit of work to do on it this weekend to bring the spare 10 cells which I haven't yet us...

Re: 24v 8s lifepo4 pack for camper conversion aux power, how to connect together?

Just decided on braid, going to use these https://www.etsy.com/uk/listing/584616732/eyelets-135575mm-100pcs-metal-copper to help protect the braid from the screwing of the bolts. so will order 14mm wide braid. question is do I want to double it up or no? I.e. double the current handling capacity. ht...

24v 8s lifepo4 pack for camper conversion aux power, how to connect together?

calb 24volt 8s3p 180ah.png So this is a mockup of the pack as I intend to build it. the copper bars are 275mm long which is annoying as 250mm are far cheaper from china so I will have to either do the parallel and series as separate or buy locally cut more expensive ones already cut to size. all in...

Re: N.E.S.E. the no solder module

very cool agniusm. these are compatible with Lebowski controllers or just using a Arduino to aggregate the temps and cut off controllers if any go too hot.

Re: building first pack using N.E.S.E system 10s8p

sorry I don't and it didn't completely burn. it just shorted until I managed to get the metal which had welded itself between the +ve and -ve to disconnect. after that it was fine (hot but ok) just didn't feel like it was smart to use it so we bought another instead.

My friend Joel and I built the exact NESE pack you are i.e. 10s8p so 80 cells he chose LG INR18650-HG2 3000mAh - 20A as he wanted capacity and current draw. He runs two 250w hub motors the 100h type ones from bms battery. using a server power supply and the cheap step up dcdc which supposedly can do...

Thanks for the update Lebowski. I am still here watching your progress. I sold all my scooters (emax's) recently to refocus my efforts on designing and making (3d printing and CNC) in my garage. I still have bobcs prototype on the mti 6pack chip and one of your newer powerboard designs. At the momen...

Re: Generic-Chinese-Bluetooth-BMS-communication-protocol

I like this a lot. I just installed a 10s one on a friends bike. would be nice to have an Arduino with an oled display for the voltages rather than a phone on the handle bars.

thanks for posting.

Re: jonescg's E-max 110s lithium conversion

Here is a sketchup8 (free version got to oldversion.com) file to help visualise what you can do with the older emax frame. I have one on ebay now if you want to bid on it. it is only at £82 so far. calb pack.jpg emaxBatteryMockups.zip ignore the batteries on racks that was my poor mans power wall.
