Lithium charger

[Toolman]

I have 2 of those HAO2 units coming to try on my 24v pack, not too much to loose

The system we make is full auto, 4 levels of protection with the final level being battery disconnect to save it from damage. I've never tried putting damaged cells with new cells, but if the cells hold voltage then I can't see a problem. The new cells will be doing all the heavy work though so just one new cell and one damaged cell might be a bit much where 2 new cells and a damaged cell would probably be ok.

Any more information on the system you make Terry?

Cheers.

It is based around cell voltage monitoring, charge cut until the high cell voltage drops, warning alarms if battery voltage goes high because something in the automated system has failed, warning alarms if the battery is drained to a level that requires careful energy use until recharging can occur so essential loads like the fridge and lights still work, a warning alarm if the battery voltage drops but the state of charge hadn't triggered an alarm, and the final protection is battery isolation if either the high or low voltage or an even lower state of charge was reached. All this is in one box that also integrates any existing charging equipment you might already have, so parts are custom designed/built to suit the particular set up. They are all open ended regarding capacity of both battery Ah and solar output so upgrades do not require a new system and minor changes can be made to suit different chargers being fitted at a later day. The idea behind the design was to use what is already there and make it future proof yet simple to diagnose and repair on the road via emails or on the phone.

Gawd, sounds like a sales pitch from a used car salesman or politician, I will go and stand in the corner as punishment, please don't ban me boss, it wasn't really product placement..... well maybe a little bit

I think you have contributed more than enough to deserve a freebie!

Well i'm interested. You already have my PM.

I only fit them as part of a system install, I don't sell them for others to install any more, it was just too hard and I really don't have the time spare now as they took twice as long to build and 4 times as long to install if you include all the emails and phone calls. I might build a plug and play box some where up the track but just at the moment, not much hope I'm afraid.

Understood. Cheers.
