Got to put energy into that battery before it can work. We are trying so much to improve battery tech, when we should be working to generate electricity more efficiently

I'm new to all this, but curious because I need to replace the battery in an old hot rod that I only drive once a week. If I bought this battery and the BMS, could I replace my lead acid? Or do I need something additional so it charges properly or whatever! Thank you.

yep this should be a much better better replacement since it has more capacity than your regular battery, be sure to have it installed in a suitable location because of its dimension

Would like to do a lev60 48volt for golf cart 600 amp controller with 5KW motor separately excited sep-ex do you recommend a kit for this? the cart used 6x8Volt lead acid
This would already be ok for a starting battery of a small engine. 12v 36/40ah lead now. What be the cheap/small minimum (weight) way to do that. Maybe add a big capacitor, for help with starting.

These cells are in many 12v batteries in bmw cars, they don’t need aditional capacitors

How long would it run a 1500watt power inverter for?
@paulbarrette2557

Full load of 1500 watts would be about 30 minutes.

@paulbarrette2557 what's the formula you used to figure that out? Do you use the input voltage or output voltage? If useing omhs law I may just done it incorrectly useing output not input. I actually used it with car/truck battery had sitting around and got about 90m running it at somewhere around 1250-1350 watt output (would ran longer but shuts off after voltage dropped below 10volts. Thanks again for your answer and any further assistance you may give. 30 yrs since learned about it in high school so a bit rusty on it trying to bring myself up to speed again. Is this correct if have 72amp hours in a battery then could run 10amps for 7.2 hours?

My answer was a quick estimation based on your 1500 watt load comment. Nominal voltage of the pack is 12.8v and the pack is 74ah. So volts X amp hours = watt hours. 12.8 X 74 = About 950 watt hours. You mentioned initially that you load was 1500 watts... 950 watt hours / 1500 watts = 0.63 hours or about 38 minutes.

Do not use this to replace a lead acid battery in a vehicle if you live in an area that gets below freezing. These batteries will go bad if charging when below freezing.
