This upgraded battery board contains holders for two 18650 unprotected rechargeable lithium cells, which reduces the internal resistance and makes it much more robust to excessive current used by motors and especially the Raspberry Pi 4.
This board is 18mm shorter than the standard board, so is much more compact.
All 10 Smart RGB LEDs are fitted as on the standard battery board, so it is fully interchangeable.
NB: This board is designed for 65mm long, unprotected 18650 cells. Longer cells may not fit and the limiting current may not be high enough to prevent the Raspberry Pi resetting
