Electron Asset Tracker Battery Type

I want to connect SparkFun’s Sunny Buddy MPPT Solar charger to the LiPo battery I got with my electron’s asset tracker.
However, the sunny buddy spec says it’s only for single cell LiPo batteries.

How many cells is the LiPo battery that comes with the electron asset tracker ?

@dorongutman, the battery is a single cell LiPo :grinning:
