Re: Anyone dealt with Tech Direct Inc. LG Chem Modules

I haven’t dealt with them for LG chem, but I bought 14 leaf modules from them in March and finally got to the point of getting my motorcycle rideable only to find out the “7kwh” pack is only useable to about 3700wh. I’m very suspicious that they sold me more like 50% capacity batteries rather than t...

Re: Running 2 or more BMS in series

What BMS were you using in that photo of the five stacked? And do you have a small display next to it or is that something separate?

Re: 5-16S Smart Tiny BMS preorder - 30/150/750A rated

Has anyone installed two of these to manage higher pack voltages? Circuit repeatedly said that no more than 48V is necessary, which is fine for electric bikes but I'm building a 28S nissan leaf powered motorcycle and am having a hell of a time finding a bms system for less than $1000. I would be mor...

Re: Kelly Controllers Configuration Program - a Definitive Translation

Hey all, I have a brand new KDHE 600 amp controller and was browsing this thread to find out more about programming it once everything is wired up. I noticed the delay function talked about for contactor opening and just wanted to let you know that I've been informed by Kelly (after purchase...) tha...

Re: ULtra Compact 1800W charger + Eltek programming

Has anyone used CAN to program two of these at once? I'd like to program the bottom half of my 2s2p stack using one arduino/CAN shield pair and the top half with another pair, but I don't know how to use CAN appropriately to communicate with multiple chargers and can't easily find other people's pos...

Re: ULtra Compact 1800W charger + Eltek programming

Yup that’s the c13/c14 standard. I’m running a similar port but specd for 20 amps and a panel mount snap in rather than bolts. Easy removal and replaceable nearly anywhere. If I can figure out how to upload a photo through my phone later I will.

Re: ULtra Compact 1800W charger + Eltek programming

If you give me dimensions for the smartpack and the S I could probably work something out. The difficulty there will be extra open space around the units. The side by side is definitely doable as are the separate input circuits. The design was originally for two C13 plugs, so 10 amp max per plug and...

Re: ULtra Compact 1800W charger + Eltek programming

EDIT: Per I don't mean to step on your toes with boards here. As an FYI I ordered a board from Per and it was very good quality and I would recommend them highly. I chose to redesign and tighten up the footprint because the housing pictured below was quite constrained. END EDIT Would any of you be i...

WTB ME1003 or similar (ME709)

Hi All, I'm working on converting a suzuki RF600 for a senior design project in college and am in need of a motor. Our budget is fairly slim but we've been lucky to run into deals and generous people so far, so if any of you have an ME1003 or ME709 that needs a new home for a good price please send ...
