Hello. Do i still need to have a solar controller for this? I have a lithium battery that im currently using.
Hi Ramon,
There is an MPPT Solar Controller built into the DC-DC charger on this battery box, so you don't need to add an extra one. You can plug your panels straight into the solar input on the battery box, and your battery will be protected with the MPPT solar controller.
Is this dcdc charger safe for my 2018 auto Hiace? Can a 200ah battery fit in it? Will my hardkorr 170w solar panel be compatible with all the above?
G'day Emma,
The DC-DC charger & battery box will be safe to use with your Hiace battery with some extra cables.
You will need:
Hardkorr 40A DC−DC Charger Wiring Kit
This will connect your Auxiliary battery to the Battery Box to charge while you are driving.
Hardkorr MC4 to Anderson Adaptor Cable 3M
The 170W Solar Panel matches up perfectly using the MC4 to Anderson Cable and the Anderson end will plug into the solar input on the Battery Box Pro. This will allow you to charge the battery with Solar while your vehicle is turned off.
Most 200Ah batteries are too long to fit in this Battery Box, as the max size is 33L x 18W x 24H cm. The largest capacity that fits is the Hardkorr 135Ah Lithium Battery that we sell.
Can you tell me the size of the box at the base? Thanks!
G'day Nicholas,
I've just measured the one on display and the base measures at: 35.3L x 22.2W cm.
