So i have been working on my brat build for a while now and i want to have the naked look so i need to get a smaller battery or one that will be able to lay down to better hide it in the bike. i have been looking for comparable batteries but am kind of green when it comes to power supplies. the battery i currently have is a lead acid 12n12a-4a-1 battery. are the only requirement of a replacement battery that it will need 12Ah? how many CCA do i need?
I have a shorai lithium battery on my 81 xj550 maxim. Lfx14a2 BS12. It has 210cca. Probably more than I need. It can handle a charging system output of 15.2, that's one thing to check. Other than that, it's a great battery, light, super small and can be installed on its side etc. Been running this brand on different bikes and no issues. Just a bit on the expensive side and should be charged with a special charger. I like that it comes with a dedicated charging port so there is no need to disconnect battery to charge.
Check the voltage with the bike running. Check at idle, 2,000 RPM, and above 3,500 RPM. Voltage should rise steadly to no more than 14.8 volts.
I have a friend that runs that runs a battery tender lithium ion battery in his 750 Shadow and he has had really good luck out of it. When I get my when I get my 650 Maxim put back together I had contemplated putting a lithium ion battery in it along with a battery tender for the winter time. is there any other is there any other brands of those Lithium-ion batteries that everybody recommends?
Have fun trying to start it after a day or two. Capacitors work fine with kickstart bikes, but electric-only not so much. A capacitor has a very fast self-discharge rate.
you need a kick start for the caps conversion . first press of the starter button will discharge the caps
Battery management system In-built Battery Management Systems - extends the life of your battery by years If LiFePo4 batteries are charged without a BMS (Battery Management System) the internal cells do not charge evenly. This can leads to a greatly reduced lifespan. If you only need the battery to last 2-3 years this is probably not an issue. But a lithium battery with an inbuilt BMS should have a lifespan of between 5 and 10 years. Vendors whose batteries do not have an inbuilt BMS recommend that you also purchase an expensive mains powered BMS charger and periodically re-balance the charge of the cells with this to extend the life of your battery. Ultrabatt avoids this hassle (and less than perfect solution) with an inbuilt microchip controlled Battery Management System that ensures that your cells are balance charged while you are riding your bike. With a Ultrabatt battery the extra cost of an external BMS is unnecessary. Each multiMIGHTY PowerBlade has a microchip controlled BMS in it to ensure near perfect balanced cell charging and extend the life of your battery by years.
