Default What's your charger? Thoughts on best charger for lithium conversion?

I have seen TC and Chargerys. A few folks indicated they are still using the lead acid chargers. Third options a cheap lower amp ebike charger. What's best or why or why not use something?

It is critical that your charger is designed for the pack voltage - number of cells you have. You can use an Ebike charger if it's set up for the same number of cells you have but it will probably charge at a fairly low rate. My Ebike charger goes to 5 amps. My cart charger goes to 17 amps so it charges more than 3 times as quickly. Both are set up for 14 cells so I can use my Ebike charger on my cart in a pinch.

VA, what charger did you find for your ebike that you can use on your cart? Did you have to mod the e-bike charger?

All the small ones I saw weren't adjustable for the output V and they all wanted to push the cells right up to 4.2v.

It'd be nice to find a cheap e-bike charger that's adjustable or has a fixed V somewhere between 54 and 57v so I can leave it in the cart and not worry if someone takes it.

I bought one of these as a temporary until I decided which charger (15 amp) I was ultimately going to use was ordered programmed shipped. Since I installed it a couple months ago its worked fine. It outputs just under 10 amps and charges the pack just fine overnight. I just installed the second pack into my other cart today and may just get a second one of these...

I got my charger from Luna Cycles. It's a 300W charger with settings from 1Amp to 5 AMP and 80, 90, 100% charge. It is only for a 52V (14cell) pack. I have two Ebikes with 52V packs and my cart has a 52V Leaf pack.

I use a cheaper ebike charger that is 1000watts. When I order it I just let them know the number of cells and battery type. There is no real information out there, but most of the chargers have 3 pots that can be adjusted for constant voltage, constant current, and current cutoff. I have used the pots to adjust voltage and amps because I built a 12s instead of a 14s.

what is your battery config. right now? (12s1p, 12s2p, 20s1p, or 20s1p?) Either way how long does it take to charge it?

And were do you purchase said charger?
