Blueshape Power Station V-Lock Battery Chargers


The BLUESHAPE power station concept is a convenient system to integrate the power of multiple V-lock batteries into a unique source that can be tapped anywhere anytime in a simultaneous dual voltage output.

The 4 available outputs, 2 at 14V (4-pins XLR) and 2 at 28V (3-pins XLR) operate in parallel an share the avaialble power in input: the output power is available simultaneously from all ports.
Due to the highly efficient internal electronics, over the 92% when delivering higher loads, the system remains cool even after hours of operation for a safe and prolonged system reliability.
Depending on which batteries are installed, the quad system can supply power as follows:

Installing 4x BV batteries, HD models (high drain):
up to 280W on the 14V output
up tp 560W on the 28V output
Installing 4x standard BV batteries (normal discharge):
up to 280W on the 14V output
up tp 480W on the 28V output
Batteries are hot-swappable to keep providing constant power without interruption, even when a battery becomes empty and needs replacement (if the remaining batteries are capable to compensate and deliver more current).

– Build in LED light with flashing mode
– Handle elements like a champ, no problem in rain.
– 30k mAh is overrated. IT’s best 15-18K mAh
– Surprisingly lightweight because it’s probably not 30k capacity:)
– 2W panel takes a while to charge battery pack
