Small size, High CCA battery

Recommended Posts

Instructions for my one say you can use any charger as long as it supplies a constant charge (doesn't increase as the battery charges)

My charger has the desulphating pulse for lead acid, but also has "gel" and "calcium" modes too.

Thread dredge.

I'm thinking that a lot of my mounting issues will evaporate if I buy a small battery.  2000cc engine. Very few accessories.

What car is it for? I run a small Shorai in my racecar and it's never had problems starting the car. My friend was running an aliexpress LiFePo4 in his K24A integra and it also worked well for a few years until the alarm flattened it a couple of times due to parking the car up for more than a month each time (they don't like being run flat).

Here's the new one that Murray just bought for his Integra. This is bigger than his original and has a few extra features:

it's got double the capacity of the last one (14ah over 7.5) volt reading on top,  and low voltage cut off at 8v (2v per cell which is their min) so it doesn't kill the battery

My brother has some tiny little helicopter battery in his Superstock. Was hellishly expensive. Cranks a fairly hot 1UZ easily.

Just bumping this thread as have been on the same mission.

Was looking at Shorai but mixed reviews.

Seems some people have run for ages no worries. Other people blowing them up regularly.

Was reccomended EarthX batteries as they have good protection onboard for shorting, low voltage, over charging, cell balancing etc.

Expensive but has a 2 year warranty which put my mind at ease compared to other options which were 6 months or a year.

If you have no parasitic load and a car you don't use regularly (like a race car with an isolator) the likes of a shorai are great.. I have one in my honda. Easily 3 months of ignoring the car and it'll fire up.. 

 

For a daily drive with stereo or alarm I would steer clear, due to the risk of bricking an expensive battery with a deep discharge...

@ Simpson I have run for the last 5 years and in the new car a Vision Battery, gel type

The first one lasted 2 years including the sitting around in the offseason's, with a mig splatter hole through the top..

They're only about $105

Aah yes vision, I have a wheelchair spec agm vision battery for my Starlet, it must be 6 or 7 years old and cheap as chips, it performs well.. 

 

I have this one in my mx5, it could be my install or cabling, but it's a little bit weak in my opinion..

I have that running a 247ci Falcon

I'd say for race uses just replace them every season or two?
