for the 40A, 2 of 20A in parallel will be enough ;-)

: Arrow: 40A is a common power in current cars ...

on my rudder or my volvo, there are several and even 60A,
therefore available without worries in a breakage. : Arrowl:

Thank you, I will opt for a 40A.
How do you advise me to test the intensity coming out of the two batteries in series while the engine is in use, in series on the +, or at the fuse terminal?
This is the last question I ask myself, and this weekend I'm starting the pieces : Cheesy:

I'll be you I'll try with an ammeter clamp, multi / ampere meters in general are not made to take too big amperage, well it depends on the ampere meter but there are many that are limited to 10A when you Connect them live while with an ammeter clamp you can climb much higher (TI principle).

: Arrow: Yes, be careful, not all current clamps measure direct current ...
I got fooled when I bought mine (specification error on the instructions).
Clamps measuring direct currents are a little more expensive ...

My multimeter can measure up to 10A I had not seen, well I will see later to find an ammeter clamp for continuous.
For the charger, I found a 3,7A slow charge car battery charger that would do the trick.

I can't wait to see the result I have a custom made mountainboard designed with solidworks and it's not easy to take and the engine interests me

What is not easy to take? the mountain board?

Mine is a prototype, it will weigh heavily considering the steel parts and the batteries, and not at all made for off-roading.

For the autonomy of my AGM battery the written discharge is for C20, that is to say that 2X12volt 18Ah (c20) in series make 36Ah for 20 hours?
it seems a lot to me :frown:

Well I have to move forward, I still have a little truck to see.

If you have two 2Ah 18V batteries in series.
It gives you 18Ah in 24V. It does not double the capacity but the voltage to put them in series. And 18Ah is equivalent to 1A for 18H or 18A for 1H.

Alors Shadow555 we don't learn our lessons ??? : Lol:

You are incorrigible ... : Lol: : Lol:
On page 1 of this topic, you made the same mistake, repeated by Dirk Pitt and me. As I have just told you again Matt113:

- In series, the voltages are added which increases the speed of rotation but does not change the capacity in Ah.

- At the same time, the Ah are added, which increases the torque

To have 24V 36Ah you need 4 batteries i.e. 2 sets of 2 batteries mounted in series that you connect in //

| battery 1 - __ + battery 2 - |
| battery 3 - __ + battery 4 - |
