lithium battery charger for small build

[crowTrobot]

AC charger to a 100 AH or 2 100 AH in the future.
my thoughts are maybe just connect it to the bus bar and then plug into a 120 when needed.
My question is what style and type of charger should I get for lithium batteries.

How fast do you want it to charge? What voltage are you talking about?

Your mileage may vary, but I use the 20amp LiTime charger. I use it on a 12v 100ah LiTime mini 12v battery that is my cpap backup. I draw 25% of the battery capacity each night and the charger is plugged into a timer so it comes on between noon and 4pm. Reality is the charger does the job in 1.5 hours.

Whatever charger you end with get one in a metal case with fan.

I didn't tested but I was looking at some 'Golf Cart' type of chargers, such as the HTRC Smart Chargers type (amazon)

- 12V 35A / 24V 18A 14.6V / 29.2V, Lithium, LiFePO4

- 48V 13A / 36V 18A, Lithium, LiFePO4

The description is a bit of a word salad. The low price is enticing but the negative reviews scared me off.

If your budget can stretch I'd suggest a Victron IP22 12/30. Fully configurable by Bluetooth and 5 year warranty.

That won’t work with the OP’s 17-volt battery.

I wonder if there is a 48V version, I noticed only 12V and 24V portable Victron chargers ?

For reliable chargers, I also got recommendation from @sunshine_eggo in a previous thread
to use the following PowerMax Series converters:

PM3 12V Series​

PM3 48V Series​

My first choice would be whatever the battery vendor suggests & sells (they know what bms they used inside). Second choice would be whatever a competing vendor suggests for their own battery lineup (LiTime offers some, via their website, via amazon).

I'd even throw out the NOCO brand of chargers (you pick the amps rating) as a third choice, which are pricey, but which have some nifty features for automatically charging any battery chemistry, and resurrecting some of them (from "zero-charge" state).

I have both LiTime and NOCO chargers, where the former is dedicated to a LiTime battery-bank, and the latter is used for balancing and other such activities among many brands of batteries.

Hope this helps ...

Great suggestion. I used the cheap 20 amp automatic chargers from Amazon at first. Finally bit the bullet and bought an IP 22 and have been very happy. Love the Bluetooth.
