Battery charger

I have a small 10amp Victron charger, have been happy with it. Mainly use it to top up batteries when the car is sitting around. They do a 30 & 50amp charger.

& they will charge lithium & you have Bluetooth as well.

Two stages is probably sufficient - bulk and float and programmable voltages so it can be set to EXACTLY the battery manager's voltage recommendations.
7 stages is sales BS for any application.
Get the biggest capacity you can afford.
Cheers,

If the 200Ah battery is from Enerdrive, match it with either their DCDC or 240v charger. Assuming a mobile installation, the DCDC is probably all you need. It has a solar MPPT input too.

I have just put in a 240ah Lithium battery, brand is personal choice. Mine is SolarKing reason 5 year warranty. Researched for a long time to get it right.

Be careful as to what is said by sellers some say they just drop in, no hassles or need to change charger, crap. If you research LifePo4 to charge properly you should use a "lithium" charger.

Mine is (Ampton 40ah) algorithm is different (volts amp rate) to normal or smart chargers. Ordinary chargers will work, but you will after a few years probably kill the battery. Also you need a good meter to read what the charge rate and what capacity is in the battery' you cant rely on voltage as lithium don't show volt drop, its a good constant flow.

Good luck and please just be very careful as to what you do as lithium batteries are very expensive.

As I just posted in another thread...

Try Victron. Long reliable history & ours have never missed a beat.

Enerdrive also have a great reputation but are more expensive.

All my electronics is Victron including battery charger & some of it is Bluetooth to track solar etc. No worth the inconvenience in the outback trying to save a few dollars.
