It's difficult to mix different type of batteries.  The lead acid battery has a nominal voltage of 2.1 V per cell, and an end voltage of 1.75 V per cell.  In a typical 6 cell battery, this means 12.6 V charged to 10.5 V discharged.  For a 10 cell NiMH pack, the values are 12 V -&gt; 10 V.  The ranges are close, but you would either need to undercharge your primary SLA battery, or you would be overcharging your NiMH batteries to 12.6 V (about 5% over).  This may progressively shorten the life of the NiMH batteries.

You might consider charging the packs separately, and then connecting (via a switch) the NiMH pack in parallel after the SLA has been run down a little.

Of course, the best option would be to use a second SLA battery.  If the charging circuit is "smart", then it should be able to charge both SLA batteries in parallel.  You could also use them in parallel.

If you are in a sunny area, you could even tie in a PV array designed for 12.6 V parallel applications.</description>

		<description>Ik maak ebike pakken.  en bevestig hen

U kunt geen AA&#039 gebruiken; s voor uw ebike, teveel verbindingen en huidig niet genoeg.

Misschien ??n of andere c&#039; s of subc&#039; s met dubbele soldeersellusjes.  er zijn sommige goede leveranciers.  controle uit 
voor sommige aardige leveranciers.

er zijn heel wat dingen die kunnen worden gedaan waaier verhogen.  Het krijgen van een amp?remeter is altijd een goede stap om te zien waar de grote macht is op uw reizen trekt. de betere banden, goede fiets wijsje-omhoog, allen helpen.  het dragen van een snelle lichtgewichtlader vermindert diepte van lossing.

verstuur me met de elektronische post.

		<description>Nooit geprobeerd, en niet zeker weet wat sla is, maar ik denk niet dat je de diepte van kwijting. Misschien langzaam neer, hoor.</description>
