Sterling power is an established small company specialising in RV and marine battery and charging systems.
Roamer and KS are small start up companies only supplying batteries.
All 3 import from China.
I am aware that there have been instances where batteries from these companies have not performed as expected due to cell inbalance .
In all cases faulty batteries have been replaced free of charge promptly.
Sterling and Roamer use prismatic cells, KS uses cylindrical cells ( similar to Battleborn).
