Maisheng MP10010D 0-100v 0-10a 1000w Adjustable Charger
These chargers are the best adjustable charger that works for all batteries from 0-100v. You can adjust the amps from 0-10a as well. These are very popular in battery labs. We have used this model charger for many years and never had any issues.
These chargers in particular we used a few times but since we got our full cabinets in we haven't used them so we are selling our inventory. We paid around $300 for these. The plug is included. Works for any 110v standard outlet. You can also use with 220v but you will need to change the plug and switch the red lever to 220v instead of 110v. You can add wire with alligator clips or whatever connector you want. On the back of the unit there is also another set of posts that you can connect ring terminals to.
I personally tested each one at different voltages so they are fully functional.
