@@Short-Builds-cs4uq I bought one of those starting aids that fits in your hand, light and compact, some smaller than 10 inches. It seems to work very well, I tested it by starting the vehicle 5 or 6 times, one after the other, in the car without a battery. The technological advancement of electric current accumulators is incredible, even more fantastic things should come in the coming years.
well actually, the average of these 1 battery is 3.7v .So this can run on any devices because its actually not 12v i think, if you count, its 77.7v .The downside is, u need to be careful with this kind of battery pack as it could catch on fire if it were falsely used.
@@fotoradiasi8340That's not how battery packs work... it's 21 x 3.7v batteries, but there are 7 in parallel (giving 7x the capacity) and then 3 sets of 7 in series (giving 3x the voltage). That's what gives the 12.6V. It's not 77V lol, you can't run anything on this battery over 12.6V (at full power).
just did the math, at $3 per cell it would be $36 per AH @12 volt. That would be $3600 for a 100 AH 12 volt battery. since they sell these in the $700 range it makes this build pretty counterproductive.
you can get them for 1-2$ with 3000mAh@3.2V would equal to exactly 125 cells for 100Ah@12V which would cost around 125-250$ not sure how you got that 3600$ number... (one cell is roughly 9.6Wh, to get to your theoretical value of $ per Ah@12V you would have around 1.25-2.5$ per Ah@12V)
can someone who know about batteries tell me if its ok to build 13s 4p that normally needs 52 batteries with just 45 batteries . That mean the last set only will have 6 batteries connectes in series with each other and in parallel with other 3 sets of 13s ????
If this is your business, hope it strives. Looks very clean.

Price ?
But 12.8V is the maximum voltage at full charge right? Wont it drop to 9-10V as the battery runs low? Is that enough to run 12V devices?

ideally your want the same voltage throughout the cells and having some in parallel and some in series would fuck up charging
Can parallel both 12v battery pack to increase aH?
Parallel connection can increase AH

You could use it to top off the car battery and start is that way if you had to.
