Batteries blew up! - Charger recommendations

[tarmfield]

Batteries just blew up so springing for a new set of Trojans, on order, and was wondering should i look at a new charger - the cart is a 48v RXV and I will be going for the T1275+ batteries.

My current charger, for some reason, is a Yamaha scr481717 MAC charger and is supposedly a solid charger. I also have a 48v maintainer from Amazon that I use if away for a long period.

Question is should i look at a new charger or will the current one do fine, there are chargers with the maintenance mode available?

If I do get a new charger - which one - looked at the Lester Summit which seems to be about the best, or there is a MODZ Max48 that seems to have the same features but significantly less money - $199 vs $370 - is the Lester worth the extra?

Thanks in advance
