Just came across this forum, starting to learn a lot! Just got my first cart that came with old dead batteries, and found that the Tech Direct 5-cell pack costs barely more than buying refurb lead acid batteries, so thinking it might be worth a shot. I'm guessing that this stone-age cart doesn't have regen or any fancy controllers, but I can't find much documentation. I have a few questions:

Will pretty much any charger work with these, and the BMS does all the hard work? Or do I need a specific charger?

I've seen some threads about the Tech Direct pack tripping its internal breaker and cutting out at full throttle. But I've also seen some threads about beefing it up with bus bars and heavier gauge cables. Think that would address some of the cutting out?

I see they say "indoor use only"... I don't plan on fording rivers or anything, but is it possible to seal these up without causing overheating concerns?

Or would I be better off just sticking with traditional lead batteries? $1500 for a more advanced lithium battery just isn't in the budget.
