Battery charger

[grantmac]

So if I have a bike in an underground parking garage where there is no power can anyone recommend me a plug in power option to keep the battery topped up. Note. There is no mains plugs available and generators are not allowed.
Some guy in my block has 2 Ferraris both under tarps and both with special units to keep his battery charged. I need to contact him but any ideas welcome

Deep cycle battery + inverter + motorcycle battery charger

Bring the deep cycle battery somewhere else periodically to charge it.

Can’t help you much, just make sure it’s lithium compatible

something like this https://www.amazon.co.uk/ECOFLOW-Po...ext&ref_=fplfs&smid=A1HGBZZ2G0TL6L&gQT=1&th=1 to power a lithium charger

It says it is rated at 245Wh and an Optimate charger uses an average of 12Wh a day so it should run for 20 days

thing is, it does not need to be on 24/7 so maybe this is overkill and you can buy a cheaper power pack as I just google portable UPS as I thought you don't want to be faffing about with separate inverter and battery.

What Wessie said. On that note, Anker is doing a lot of offers on their new line of portable stations. They seem awesome on paper. A friend just bought one.

If you are going for just a battery or simple power station, keep in mind that DC to DC chargers do exist, and you do not waste the power inverting from 12 to 220 to then get back to 12 again.

Optimate sells them and so does ctek.
