I have used this very battery on my 964 and it is good as long as you do as you say either use the cut out switch or drip charger each time. If you live in a cold environment especially. I however did not have the cut out switch and would think I would drive enough to keep it charged then three days goes by and the battery is drained. I ended up switching back after six or seven jumps and the fear of being stranded on a road trip. Thanks for video. Good idea for those more conscious to routine than me. Cheers

I've been on road trips with it and when the car was being used every day it was fine.. maybe I was luckier than you? Also I have no radio or any other extra electric drain like air con.. maybe that makes a difference.

2020. I've had an Excide 115AH/205 Reserve Capacity minutes at @20a deep cycle marine ($100 at home depot) in my van for a year now and it's working great. I had to customize my battery tray to hold 13" vs OEM 9". I've been looking at some of the 300AH Lithium batteries out there . the challenge is they are 20" long and they still cost around $3k. But that batteries returns 900 Reserve Capacity minutes @20a which is over 4x longer use. The difference for me would mean i could run a small 200watt AC overnight.

Now the only similar model they have says 480ca instead of cca and 8.0ah instead of 26-35. I have a built Subaru and ran it with a 16 cell ballistic for a while, but it couldn't sit a day or two before the alarm depleted it and eventually wouldn't recover. Cranked the car very quickly though, impressive. I can't run a disconnect switch for my daily, value it not getting stolen too much.

I was always worried about overcharging because these batteries will be in a serious trouble is they're charged as a cell reaches 4.2V.. well, i solved it by myself! Built myself a battery like this, using 3S 18650 li-ions (3000mah per cell) 6P, 18 cells total.. overcharging is solved by a circuit that switch when the battery is charged to 12.6V and all surplus current sends to be "wasted" as heat, i added quite a big heatsink to to the job, it's got half a kilo (aluminium) and all worx awesome.. i have the battery for about 8 years now and it might serve another 20+ years, lost only 10% of it's original capacity!

I have watched a million jump pack tests and even big old V8 engines don't need more than ca 200 A to crank. These batteries are just way more powerful than they have to be, because you might catch them on their bad day, at -30 C, etc... in the UK, this will probably be sufficient three times over, still.

These batteries are designed for use in motorcycles or atv's, are there any drawbacks to using it in a car? Have you had any problems with it or are there certain operating conditions? Can you use it as the primary battery in your daily driver? Just curious how well it works because people spend in excess of $1,000 for a lightweight battery that still weighs double the weight of this.

Your calculations on the available power from the lead acid battery pack is inaccurate. While 20Ah x 72v should = 1.44Kwh, it really doesn't. The amount of usable power stored in a lead acid deep cycle battery is generally expected to be 50%-80% of the rated value and the rated value is at a 20 hour rate... So you can get 50%-80% of the rated capacity but only if you draw that power over 20 hours. The 20 hour rating(and ALL lead acid ratings in general) is misleading. To have any real idea of the available power from a lead acid battery you have to take into account Peukert’s Law. The more current you draw from a lead acid cell the less efficient it becomes. At very high drain rates you will lose a significant amount of power due to this problem with lead acid cells... and cheaper lead acid batteries tend to suffer more from this than better batteries. A Peukert’s Law constant of 1.1 may be seen with VERY high quality batteries, but might 1.4+ on cheap no name lead acid batteries. At a constant of 1.4, drawing 10 amps from a 20Ah battery you'll reach 80% discharge in around 30 minutes... not the 1.5 hours you might expect if not taking Peukert’s Law into account, and not the 2 hours you might expect if not taking into account Peukert’s Law or the maximum depth of discharge. Something else to consider in respect to the depth of discharge in lead acid cells is battery quality... with cheap batteries 50% is recomended since beyond that they begin to see a lot of damage and will have a much shorter life, with good batteries you can usually discharge to 80% and still get the same number of charge cycles as you could on a cheap battery at 50%. Lithium cells don't really have this problem, at least not to the point of being a problem... so you really only need a lithium battery pack rated for around half the rated capacity of the lead acid cells to get similar performance... and as a bonus you don't have the same amount of voltage drop over the discharge range that you do with lead acid batteries. These are just a couple of reasons that lithium batteries are becoming more popular with the RV crowd.
