12v K2 battery 12.8v 6,4ah K2B12V7EB
Regular price $29.99
Here are K2 12v batteries with a BMS. These came out of medical applications and were used as backup only so these will work great and are sitting at nominal voltage. The 2nd photo shows the data sheet with dimensions. There is a BMS in these as well. It amazes me that these sell to hospitals new for over $140 each. These have 8x 26650 K2 3200mah cells inside. 8 cells, medical grade BMS, beautiful enclosure, already assembled, plug and play for just $29.99. The BMS can handle 24a continuous or 40a on a pulse.
