We came to class today only to find that our vehicle lift was sitting in a puddle of hydraulic fluid! The lift has a leaking seal on the hydraulic cylinder. This is a big issue because we can not lift our MR2 up to work on our BMS. We are trying now to find a replacement lift(donation) or to get this one fixed. It is an old lift and may have seen its' better days, so a replacement may be in order.
On the plus side our batteries have all stabilized to 3.37 volts after a long charge period, essentially pre-balancing our pack for when we install the BMS. Of course, we need a lift to do so! Always something.

Today, we began removing all of the Thundersky batteries so we can top balance the entire set in parallel. By doing this, we will have a balanced pack, and the BMS will have an easier job for the initial few charge cycles.
