Question 1

What's the difference between this and the jac0348man?

Accepted Answer

So, this is a good question. 
This JAC0348-R is a 3-stage fully automatic CHARGER. It is designed to be the only charger & maintainer you need for 48V battery systems that are up to 40AH capacity. Since most people asking about this are looking at a golf cart battery application, it means that this charger is NOT designed for golf carts. Quite simply, golf cart batteries are too large for this charger (typically about 150-200AH) and it will not be able to charge them enough to achieve float voltage - and it will burn itself up trying. You might get away with it for a while if you are meticulous about keeping your batteries fully charged before connecting it, but eventually you will probably burn it up.

On the other hand, the JAC0348MAN is DESIGNED to be a MAINTAINER for 48V battery systems up to 300AH - NOT a charger. In other words - you still need a primary charger for your golf cart, but after the batteries are fully charged, you can leave the JAC0348MAN connected for an indefinite period and it will maintain the batteries. Technically, it is a 2-stage design that bulk charges below a set voltage, then transitions to float/maintenance output. If the voltage falls below the set-point, it reverts to bulk charge mode and repeats the cycle in order to keep the batteries at a healthy voltage.

Bottom line - if it's for a golf cart, get the model that's designed for the task - the JAC0348MAN. They are approximately the same price anyway.

Question 2

My chart has 7 6 volt batteries I think I need a 42 volt maintainer and do you make one I could buy

Accepted Answer

Hi,
Yes, we have a Schauer 42 volt maintainer for golf carts. The golf cart maintainer specs are slightly different from this charger (this unit is for smaller battery systems, only for 40 amp hour capacity or less). The maintainer you need is similar to the JAC0348MAN that you can find here on Amazon, which is a 48V unit. We do not sell the 42V maintainer on Amazon, but you can call PLP Battery Supply to order at 800-642-3451. You can also find it on the PLP Battery website, search for JAC0342MAN. Hope this info helps.
Thanks,

Question 3

I have 4- 12  volt 12 ah batteries I use for a handicap scooter. I want to maintain a charge in the winter so the batteries dont die out. Is this good

Accepted Answer

Yes, this would be an excellent charger for your scooter. It may be left connected to the batteries indefinitely, maintaining the batteries at a healthy voltage during storage - it will not damage the batteries or charger.
