The Fogstar Drift 12V 172Ah DIN Fit is the simplest lithium upgrade for any campervan or motorhome that came with a standard lead-acid leisure battery. If it fits an H8 tray, this drops straight in — no bracket modification, no rewiring, no custom fabrication.

Built to the H8 / L5 DIN footprint (358.8mm x 177.3mm x 187.6mm), it replaces the typical 80–110Ah AGM at around half the weight and gives you 172Ah of full, usable LiFePO4 capacity in return. It also arrives with the full Gen2 feature set: Bluetooth monitoring, Victron CANbus, active cell balancing, and a built-in heater that keeps it charging down to -20°C.

Key features:

  
172Ah / 2,201Wh capacity in a standard H8 DIN case — true drop-in replacement
  
Fits any battery tray designed for H8 / L5 lead-acid batteries
  
250A Smart BMS with active cell balancing
