Lawnmower , Marine SLA batteries ?

[samsam]

Hi , I m just orderring new crystal convertion kit , coming soon on a few week , & i have a question Can i use the SLA batteries ( Lawnmowers , Marine batteries ... ) for my coming 36v , 400w kit , because i saw at Walmart store lastweek ,they very cheap ( 12v , 200 cca ) on sale for 25$ each .

Thank you for all help , have a nice day

Sure.

Those batteries might be mighty heavy though. If your bike can handle the weight and you don't have big hills to climb, you will have tremendous range.

200cca being Cold Cracking Amps, do you know what the AH (amp hour) rating is? That will give you a better idea of the range.

I asked a very similar question to the guy at my local Battery Plus store, he told me to avoid them for 2 reasons.

the first being they don't like to be deep cycled at all, and the plates will be damaged if you try to use them like the normal SLAs for scooters or bikes

The other is they are designed for maximum discharge. they can deliver 200 cranking amps for 30 seconds or so, then they are dead. Thats less than 2 amp hours capacity, just a super high discharge rate.

the ~$42.96 marine deep cycle is the only one i'd buy there, size 24

Several years ago when I was looking for longer range on my Z.A.P. friction drive motor I explored the option of lawnmower batteries. I went ahead and bought one, stopped at an auto parts store and bought sufficient stuff to make a second switch, and wired the lawnmower battery placing it in the front basket on my bike.

It worked. The Z.A.P. with the factory 12 volt 21 AH battery would propel the bike, without peddling at 8 - 9 MPH, I have no idea how far as I always pedaled. The lawnmower battery propelled the bike at less than two MPH! This was with a heavier battery, by far, and with what I thought would be good AH but were in fact CCA.

Since I had no further use for the battery it sat in my workshop for several years before I eventually threw it away. I did wind up buying the much more expensive Z.A.P. replacement battery and used that and it worked great extending my range to 30 - 35 miles with pedal assist and a quick stop to change the wires over.

So, IMHO, you had a good idea but been there, done that, got the T shirt and it didn't work.

Bite the bullet, BB 12 V 12 AH batteries aren't that expensive, especially if you shop around and they will last quite awhile or at least long enough for you to do all the research you want before investing in more expensive batteries.
