Are these batteries shipped with the lead post adaptors for Model 3?

They sure do! They are ready to rock and roll right out of the box, nothing else needed but a 10mm wrench to do the swap (Model 3 swap is really easy to do!)

Does bms stop charging below 0 degrees c?

From the manufacturer website: Thermal chambers allow simulation of extreme heat and extreme cold conditions. Our in-house Thermotron chamber allows us to push the envelope with capabilities of reaching down to -70° Celsius (-94° F) on the low side and up to 185° Celsius (365° F) on the high side. Testing has been performed on all products we sell (per IEC 60068-2-1) so we can stand behind our batteries 100%.

Can they be put in series for a 24v system? How many cycles?

They can be put in series, 24V system is no problem for 2 of these to run. Cycle life depends on a variety of factors (depth of discharge, charge and discharge rates as well as temperatures) but in ideal conditions we get 4000+ cycles from these units. In less than ideal 2000+ cycles is expected. In very harsh environment and usage case, 1000+.

Where are the fine prints for the warranty? ohmmu.com has 0 warranty info. Considering one of the review below, that's not a good sign.

Our apologies, our warranty is 48 months from purchase date and it is 100% coverage, any issues and we replace it. To start the replacement process you contact us via our website (pop-up chat) and we will ship a replacement same-day with a return label for you to send back your defective unit. We are working on the “legal language” way to say all this and will then have it posted on our site more clearly and detailed. Thank you!
