Charging auxiliary battery while using WFP pumps
« on: September 26, 2016, 05:54:24 pm »
Can you charge an auxiliary battery from the mains while the battery is hooked up and in use? I'm on a large commercial job all week without moving the van during the day. By 1pm today it was starting to lose pressure and displaying battery low on flow controller.

Stick a battery charger on it overnight and it will be fine,

Im using a 140Ah. Charged it all day yesterday. It's only a couple years old  but maybe on its way out. The cells didn't look great when I checked if it needed topping up. Got it on charge again now overnight. It's probably only been charged from mains 3 or 4 times since new as I've been getting by with the split charge relay.

Wouldnt pose a problem for me, as i use a solar panal on top of van and on less sunnier days like today, a back up solar panal that i stick on as well.
Charging whilst working or if ive pulled up for lunch etc, park in direct sunlight and battery nicely topped up by time ive finished my lunch. I dont find i have to worry about the charge in battery.

I think your battery has had it, on an overnight charge you should get a good eight hours or more.

Where did you pick up your solar charger from? Is it a plug and play? Cost? I don't fancy buying a new battery as my van and system comes in February

I have no problem using customers power if/when required to charge the battery and carry on working at the same time if need be.
