tortron Posted January 4, 2020 Share Posted January 4, 2020 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) Quote Link to comment Share on other sites More sharing options...
Roman Posted January 6, 2020 Share Posted January 6, 2020 Yeah and no desulphating thingy built into the charger either. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted September 2, 2020 Share Posted September 2, 2020 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. Quote Link to comment Share on other sites More sharing options...

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). 1 Quote Link to comment Share on other sites More sharing options...

Truenotch Posted September 2, 2020 Share Posted September 2, 2020 Here's the new one that Murray just bought for his Integra. This is bigger than his original and has a few extra features: Quote 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 https://www.aliexpress.com/item/33022941096.html?spm=a2g0s.9042311.0.0.a8ef4c4d8WUncV 1 1 Quote Link to comment Share on other sites More sharing options...

MACKAZ Posted September 3, 2020 Share Posted September 3, 2020 My brother has some tiny little helicopter battery in his Superstock. Was hellishly expensive. Cranks a fairly hot 1UZ easily. Quote Link to comment Share on other sites More sharing options...

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. https://earthxbatteries.com/our-batteries/lithium-battery-technology 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... 1 Quote Link to comment Share on other sites More sharing options...
CUL8R Posted September 3, 2020 Share Posted September 3, 2020 @ 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 2 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted September 3, 2020 Share Posted September 3, 2020 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.. https://yhipower.co.nz/catalog/vision---hp-102378.htmx?selectedProduct=856 Quote Link to comment Share on other sites More sharing options...
CUL8R Posted September 3, 2020 Share Posted September 3, 2020 I have that running a 247ci Falcon I'd say for race uses just replace them every season or two? Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted September 3, 2020 Share Posted September 3, 2020 Because modified cars love to let the smoke out, I'm going to be fitting an isolator 100%. Quote Link to comment Share on other sites More sharing options...
h4nd Posted April 30, 2022 Share Posted April 30, 2022 Rebumping the thread. My old GSXR battery has gone open cct. Unsure if overcharged by by the 2W solar I have, but seems unlikely, the volts looked ok when I semi-regularly checked it. No joy bringing it back by borrowing smart chargers from @RUNAMUCK and @ajg193 It's motobatt MBTX14AU https://www.tayna.co.uk/motorcycle-batteries/f/suzuki/gsx-r-1100-g-n/ and I was considering something from a local supplier like https://www.mrpositive.co.nz/shorai-lfx14l5-bs12-210cca-high-performance-lithium-battery/ (14Ah, 210CCA $332) But reading the thread, it's Shorei, as @Roman mentioned had mixed reviews. That earlier ali link now does not deliver to NZ. Racetek is not a good mechanical fit, and $1100 for 10Ah (not 14Ah). Am trolling thru Ali Express, and seeing a number of sellers who don't ship, and bad spellerings on batteries and info sheets. Update: digging into the data sheet here https://shoraipower.com/battery-specifications The Shorei battery 14Ah only accepts a 14A charge. The LiFePo4 cells are lower impedance than the PbSO4, and will probably hoover up current faster. GSXR is 405W alternator, so assuming at 13.8V (worst case?), so maybe 30A+ (with the lights off). This might explain some failures folks are seeing. Re-update: This series, with the terrible spelling etc, claims 10C charging (so 100A for a 10Ah battery) https://www.aliexpress.com/item/1005002564457369.html Quote Link to comment Share on other sites More sharing options...

governorsam Posted April 30, 2022 Share Posted April 30, 2022 Have had a few motobatt batteries die on me. have gone back to normal lead acid and no more problems. bonneville and goldwing ate motobatts. have a hookup for katana brand battery’s through work. (Century batterys) han no problems with them. heard a few bike shops stopped stocking yellow motobatts due to the number of claims. 1 Quote Link to comment Share on other sites More sharing options...
kicker Posted April 30, 2022 Share Posted April 30, 2022 My local shop stopped stocking motobatt for that reason, they sell the Poweroad brand now instead. 1 Quote Link to comment Share on other sites More sharing options...
h4nd Posted April 30, 2022 Share Posted April 30, 2022 I may try a LiFePo4 even though it's only 8Ah, it'll crank harder, and if it can't crank long enough I have other uses for it (and should refurb / tune the bike). Come to think of it, I should carefully check the alternator before I order. I built an alarm one time for the bike which ran on almost zero standby current. The flashing LED warning LED drained the drained the batt in a couple of days though. Quote Link to comment Share on other sites More sharing options...
