Re: Friendly reminder. Winter (@northern hemisphere) is kickin' in.

Is it really that bad? Thousands of power tools are used and stored in unheated areas all winter. I have a dmm that lives in my car year round and it's still working. Where I work, we have to leave our phones in the vehicle so after a 12 hour night shift at -20 my phone isn't too happy but it's sti...

Do not charge your li-ion cells below 10 degrees Celsius.

Re: LG Chem 10S2P battery modules - 37V30Ah - 1100 wh [EU] UPDATE NOV 18

Hello, I ordered you 4 modules 10s2p-37V30Ah last night. Currently I use two packs Li-po 16s10c16Ah. To have the same configuration to get the same voltage on my vehicle. I need to turn the 10s modules into 8s. This seems possible to do or is it too complicated ? Thank you in advance Peter Hi Peter...

Are the black plastic dividers bonded together and difficult to separate? Or are only the tabs welded together to make the electrical connections? There is some overlaying plastic protection you need to get rid off but generally speaking the dividers are seperate. The cells on their own are physica...

Re: LG Chem 10S2P battery modules - 37V30Ah - 1100 wh [EU] UPDATE NOV 18

Hello Can you think it's possible to disassembled for build 14s battery? Yes, as mentioned above, it is possible but not in a 'bolt-off bolt-on' way. The relative easy way is that you dissect two modules in 7s and 3s and make a new connection between two 7S sections. Leaving two 3s modules spare. T...

Thanks, no worries I think it will all be good. I don't think the balancing loads will ever be higher than the balance cables can handle during discharge. Except for total cell loss perhaps. I will just Y-wire the balance cables. Two strings with two BMS is madness and only good and safe under cert...

Man, sucks these are not available in the US. I’ve been trying to figure out an easy 20s pack from used ev modules. These are perfect and a great deal!
Sorry to hear.
Follow Jehu Garcia (jehugarcia) on Youtube. He is from the USA and posts leads to good batteries regularly.

Re: EU - Group buy - all QS Motors' offer

I ordered five hub motors at once in a QS groupbuy but they all were slightly different in specs.
My experience was that they dont really offer interesting discounts if you order different items in small numbers.
You only benefit in transport costs.
